The Cisco AS5800 Universal Access Server is equipped with modem cards for converting analog pulse code modulation (PCM) bitstreams to digital data. There are 2 types of modem cards currently supported on your access server---Cisco's Modem ISDN Channel Aggregation (MICA) hex modem modules (HMMs) and double-density modem modules (DMMs).
This document explains how to remove and replace the double-density modem card in the Cisco 5814 dial shelf. It also includes steps for configuring your software, and verifying and troubleshooting your modem card installation.
The following sections are included in this document:
For information regarding the Cisco AS5800 Universal Access Server that is beyond the scope of this document or for additional information, use the following resources:
The Cisco AS5800 Universal Access Server is a high-density, ISDN and modem WAN aggregation system that provides both digital and analog call termination. It is intended to be used in service provider dial point-of-presence (POP), or centralized enterprise dial environments.
The access server can handle all-analog or all-digital calls, or any combination of analog and digital calls. There is no need to build configurations that trade off analog and digital ports. All modem standards (V.34, V.42bis, and so forth) and features are supported, including dial-in and dial-out.
The access server chassis components include a Cisco 5814 dial shelf and a Cisco 7206 router shelf. An optional AC power shelf is also available. The dial shelf and router shelf are bundled, and can be ordered to support either AC or DC power. Included in the dial shelf is a blower assembly, filter module, and DC power entry modules (PEMs). Also included in the bundled system are ingress trunk cards, modem cards, dial shelf controller cards, Flash memory PCMCIA cards, cables, and Cisco IOS software. The dial shelf feature cards and host router shelf communicate via a dial shelf interconnect cable.
The router shelf supports the dial shelf and performs all routing and packet processing. The router shelf also houses the main system software images.
The dial shelf contains 14 slots and supports up to 10 modem cards that provide the following functions:
Figure 1 shows the front view of a fully configured Cisco AS5800 Universal Access Server.
Figure 2 shows the rear view of a fully configured Cisco AS5800 Universal Access Server.
The Cisco AS5800 Universal Access Server is equipped with a maximum of 10 modem cards that use Cisco's Modem ISDN Channel Aggregation (MICA) technology with upgradeable firmware. Each modem card plugs directly into the dial shelf backplane and has no external connections. Each modem card has 5 LEDs, which indicate modem card status.
The Cisco AS5800 Universal Access Server has the capability of terminating up to 1,344 modem connections when equipped with 10 double-density modem cards and 2 CT3 trunk cards.
Each double-density modem card contains 12 DMM SIMMS. Each DMM SIMM contains 12 digital modems.
Figure 3 shows the double-density modem card components.
The double-density modem card performs the following functions:
Modem cards can be installed in slots numbered slots 0-11on the dial shelf backplane; however, Cisco recommends you install modem cards in dial shelf slots 2-11 and reserve slots 0 and 1 for trunk cards. (Trunk cards are required for call termination and can only operate in slots 0 through 5.)
Figure 4 shows a fully configured Cisco 5814 dial shelf with 10 modem cards installed.
The double-density modem card has 5 LEDs (see Figure 5) to indicate modem card status.
During normal operation, all 5 LEDs light when the system is powered ON and the modem cards are ready. When the modem card CPU software image starts running, it shuts off all LEDs except the power LED. Modem card LEDs are listed in Table 1.
| Name | Color | Description |
|---|---|---|
PWR LED | Green | Power LED---Lights when card is powered ON. |
Maint LED | Yellow | Maintenance LED---Lights when there are no active calls on the card, and you have completed a card-level software busyout. Indicates the card is ready to be removed. |
HCPU LED | Green | Host CPU LED---Lights when the modem card passes diagnostics and the modem card CPU is operating properly. |
Modems LED | Green | Modem LED---Lights when all modem modules present have passed diagnostics and are operating properly. Remains OFF if 1 or more modem modules are absent on the card or if 1 or more modems fails diagnostics. |
Calls LED | Green | Calls LED---Lights when at least 1 active call is switched through the modem card. |
Modem card software is automatically downloaded to a modem card from the router shelf when you boot the system for the first time, or when you insert a modem card while the system is operating. When you insert modem cards while the system is operating, the system software recognizes the cards, and the router shelf downloads the required Cisco IOS image to the cards.
The modem firmware image (also known as portware) is bundled with the Cisco IOS modem card image. The firmware image uses an auto detect mechanism, which enables the modem to service multiple modem call types. A modem detects the call type and automatically configures itself for that operation.
The modems can be programmed to collect the ANI (calling number) and DNIS (called number) digits for caller identification information. This occurs only when the trunk cards are configured in Channel Associated Signaling (CAS) mode. The modem passes the ANI/DNIS information to the modem card software via a portware mailbox message.
The modem cards support the modem standards and features listed in Table 2:

Your Cisco AS5800 Universal Access Server supports online insertion and removal (OIR). This feature allows you to remove and replace a feature card (trunk card or modem card) or dial shelf controller card while the system is operating, without affecting system operation.
Each dial shelf controller card and feature card contains a female connector with which it connects to the system backplane. Each male backplane connector comprises a set of tiered pins in 2 lengths. The backplane pins send specific signals to the system as they make contact with the card connectors. The system assesses the signals it receives and the order in which it receives them to determine what event is occurring and what task it needs to perform, such as reinitializing new interfaces or shutting down removed ones.
Each dial shelf controller card and feature card is designed with 2 ejector levers to be used when you install or remove a card, as shown in Figure 7. The function of the ejector levers is to align and securely seat the card connectors in the backplane.
Do not force the dial shelf controller cards or feature cards into a slot, as you can damage the backplane connector pins if they are not aligned properly with the card connectors.
To avoid erroneous failure messages, you must allow at least 15 seconds for the system to reinitialize and note current interface configurations before you remove or insert a dial shelf controller card or feature card in the dial shelf.
This section provides safety and ESD-prevention guidelines to help you avoid injury to yourself and avoid damage to the equipment. Cisco recommends the following safety guidelines when working with any equipment that connects to electrical power or telephone wiring:
Cisco recommends the following guidelines when working with any equipment that is connected to telephone wiring or to other network cabling:
Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit cards are improperly handled and results in complete or intermittent failures.
The system feature cards and dial shelf controller cards consist of a printed circuit card that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and ejector levers are integral components of the carrier. Handle cards by their carrier edges or ejector levers only; never touch the printed circuitry, card components, or connector pins.
Although the metal carrier helps to protect the printed circuitry from ESD, you should wear a preventive antistatic strap whenever handling the feature cards or dial shelf controller cards. Ensure that the strap makes good skin contact and connect the strap's clip to an unpainted chassis surface to safely channel unwanted ESD voltages to ground.
If no wrist strap is available, ground yourself by touching the metal part of the chassis.
Following are guidelines for preventing ESD damage:
 | Caution Periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms. |

Depending on your configuration requirements, you might need to replace or install new modem cards in your Cisco 5814 dial shelf. Although slot 0 through slot 11 accept modem cards, Cisco recommends you install modem cards in slot 2 through slot 11 and reserve slot 0 and slot 1 for trunk cards. (Trunk cards are required for call termination and can only operate in slot 0 through slot 5.)
This section describes the steps to remove and replace a modem card from the dial shelf, and includes the following items:
If you are replacing a modem card with a new modem card of the same type in the same slot, the system software recognizes the new modem card interfaces and brings them up automatically. No additional configuration is needed.
If you are replacing an HMM SIMM modem card with a double-density modem card (or vice versa), you need to modify your running configuration file. Software configuration commands are defined in the section "Configuring the Modems" section.
For additional software configuration information, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide that shipped with your system.
| Caution To avoid erroneous failure messages, remove or insert only one modem card at a time. Also, after inserting or removing a modem card, allow at least 15 seconds before removing or inserting another modem card so that the system can reinitialize and note the current configuration of all interfaces. |
To remove an individual modem without dropping calls or connections, you must first take the modem out of service by using the busyout command to busyout DS0s and modem resources as calls are completed. The busyout command is executed on a per-card (slot) basis.
The busyout command has the format busyout shelf-number/slot-number, where shelf number is a user-designated value from 0-9999, and slot number is 0-11. The user designated value is generally configured during the initial setup configuration process.
Table 3 lists the command lines used to busyout a modem card located in slot 2 of dial shelf 5. To input the busyout command, you must be in privileged EXEC mode.
| Step | Command1 | Description | ||
|---|---|---|---|---|
|
| Enter the enable command. Enter your password. You are in privileged EXEC mode when the prompt changes to | ||
|
| Enter global configuration mode by typing the configure command. The example is using the terminal configuration option. You are in global configuration mode when the prompt changes to | ||
| | Set the low free modem threshold. This ensures that the corresponding DSOs are busied out when the modem resources are busied out. | ||
|
| Type the exit command to exit out of line configuration mode [or] Press the return key to verify your command registers, then type Ctrl-Z to return to privileged EXEC mode.
| ||
| | Busy out the modem resources and DSOs of slot 2 in dial shelf 5. | ||
| | Display the busyout list. Verify that slot 2 has been busied out and that there are no active calls before removing the double density modem card. Example: Slot 5/2: Busyout (no calls incoming) |
The following parts and tools are required to remove and replace the double-density modem card. If you need additional equipment, contact a service representative for ordering information.
To remove a modem card from the Cisco 5814 dial shelf chassis, follow these steps:
| Caution Double-density modem cards weigh 8.0 lb (3.6 kg) each. Use both hands when removing or replacing a modem card. |
Step 1 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
Step 2 Initialize the software busyout procedure by entering the busyout command (see the section "The Busyout Command-Line Interface").
Step 3 Verify the yellow maintenance LED on the modem card front panel lights, which indicates the card is offline and ready to be removed.
| Caution To prevent ESD damage, handle modem cards by ejector levers and carrier edges only, and use an ESD-preventive wrist strap or other grounding device. |
Step 4 Using a Number 2 Phillips screwdriver, loosen the panel fasteners on the modem card front panel.
Step 5 Pull either the top or bottom ejector lever away from the modem card front panel to disengage the modem card from the backplane connector, as shown in Figure 6.
| Caution Always use the ejector levers to disengage or seat trunk cards, modem cards, or dial shelf controller cards in the dial shelf backplane. Failure to do so can cause erroneous system error messages indicating a card failure. However, do not use the ejector levers to lift or support the weight of the cards. |
Step 6 Grasp the ejector levers and pull the modem card partially out of the dial shelf slot until you can grasp the modem card front panel with one hand. Place your other hand under the modem card to balance the weight of the card as you pull it from the slot, as shown in Figure 7.
Step 7 Pull the modem card straight out of the slot. Avoid touching the circuitry or any connector pins.
Step 8 Place the removed card on an antistatic mat or foam pad until you are ready to reinstall it in the chassis. If you plan to return the card to the factory, place it in an antistatic bag.
| Caution To prevent the overheating of internal components, always install blank filler cards (DS58-BLANK=) in empty slots to maintain the proper airflow across the cards. |
| Caution To avoid erroneous failure messages, remove or insert only one modem card at a time. Also, after inserting or removing a modem card, allow at least 15 seconds before removing or inserting another modem card so that the system can reinitialize and note the current configuration of all interfaces. |
This completes the modem card removal procedure. To install or replace a modem card, proceed to the section "Replacing a Modem Card."
To replace or install the modem card in the Cisco 5814 dial shelf, follow these steps:

| Caution To prevent ESD damage, handle modem cards by ejector levers and carrier edges only, and use an ESD-preventive wrist strap or other grounding device. |
Step 2 Carefully align the modem card carrier guides with top and bottom grooves in the slot. Avoid touching the circuitry or any connector pins.
Step 3 Slide the carrier into the slot until the ejector levers make contact with the chassis frame.
Step 4 Seat the modem card in the backplane by pushing the card firmly until the ejector levers fold in toward the modem card front panel, and the front panel is flush with the chassis frame.
| Caution Always use the ejector levers to disengage or seat trunk cards, modem cards, or dial shelf controller cards in the dial shelf backplane. Failure to do so can cause erroneous system error messages indicating a card failure. However, do not use the ejector levers to lift or support the weight of the cards. |
Step 5 Tighten the panel fasteners using a Number 2 Phillips screwdriver. This secures the backplane connection and ensures proper EMI shielding.
| Caution Always tighten the panel fasteners on modem cards. These screws prevent accidental removal and provide proper grounding for the system. |
Step 6 Disengage software busyout using the busyout command. See the section "The Busyout Command-Line Interface" for further instruction.
Step 7 Repeat Step 2 through Step 6 for any other modem cards you want to install.
| Caution To avoid erroneous failure messages, remove or insert only one modem card at a time. Also, after inserting or removing a modem card, allow at least 15 seconds before removing or inserting another modem card so that the system can reinitialize and note the current configuration of all interfaces. |
Step 8 Install a blank filler card (DS58-BLANK=) in all empty card slots to keep the chassis dust free and to maintain proper airflow.
| Caution To prevent the overheating of internal components, always install blank filler cards (DS58-BLANK=) in empty slots to maintain the proper airflow across the cards. |
This completes the modem card replacement procedure. Proceed to the section "Verifying and Troubleshooting the Installation."
During normal operation, all 5 modem card LEDs light when the modem card is powered ON. When the modem card CPU software starts running, it shuts off all LEDs except the power LED. Later, LEDs light again as described in earlier in this document.
To complete the installation, verify the LEDs operate properly by observing the following LED states on the modem card:
For further installation troubleshooting information, refer to the Cisco AS5800 Universal Access Server Hardware Installation and Configuration Guide. If you have any questions or need assistance, proceed to the section "Cisco Connection Online."
The Cisco 5814 dial shelf is designed to recognize modem cards in slot 0 through slot 11 within the dial shelf chassis. If you are installing 10 modem cards in the dial shelf chassis, Cisco recommends you install modem cards in slot 2 through slot 11 and reserve slot 0 and slot 1 for trunk cards.
If you are replacing a modem card in the same slot as the one you just removed, the system automatically recognizes the previous system configuration; no other configuration is needed.
