This document explains how to remove and replace the dial shelf controller card in the Cisco 5814 dial shelf chassis in the Cisco AS5800 Universal Access Server. Also included are instructions for verifying the installation. The dial shelf controller card serves as the interface between the dial shelf and the Cisco 7206 router shelf.
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 Cisco AS5800 Universal 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-input 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 dial shelf contains 14 slots (numbered 0 through 13 on the backplane) and can support up to 10 modem cards, 2 trunk cards, and 2 dial shelf controller cards. Slots 12 and 13 are dedicated slots for the dial shelf controller card(s). A single dial shelf controller card can be installed in either slot 12 or slot 13.
Redundancy is provided when 2 Dial Shelf Controllers (DSCs) are installed in the Dial Shelf. One DSC functions as a master. The master DCS provides all of the DCS functionality (master clock, environmental monitoring, etc.) for the Dial Shelf. The 2nd DSC functions as a slave that monitors the master DSC. The slave DSC takes over DSC functionality when it detects a serious failure in the master DSC.
The router shelf supports the dial shelf and performs all routing and packet processing. The router shelf also houses the main system software images.
Figure 1 shows a front view of a fully configured Cisco AS5800 Universal Access Server. Figure 3 shows a rear view.
The dial shelf controller card is the main processor card for the dial shelf, and it performs the following functions:
You install the dial shelf controller card in the Cisco 5814 dial shelf in either of the 2 far-right slots (numbered on the backplane as 12 and 13). The card plugs directly into the backplane.
The dial shelf controller card consists of the following components:

Each dial shelf controller card contains a block of logic referred to as the common logic and system clocks. This block generates the backplane Stratum-4 compliant 4-MHz and 8-KHz clocks used for interface timing and for the TDM bus data movement. The common logic can use a variety of sources to generate this system timing, including an E1 or T1 signal input from the BNC connector on the dial shelf controller card front panel.
Only one common logic is active a time, indicated by the CLK (clock) LED on the dial shelf controller card front panel. The active common logic is user-selectable and is independent from each dial shelf controller card. This assures that if you need to replace a dial shelf controller card, or if the slave dial shelf controller card becomes the master, clocking remains stable. The selected common logic should not be changed during normal operation unless a hardware failure in the dial shelf controller card is suspected or diagnosed.
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 equipment that connects to electrical power or telephone wiring:
Electrostatic discharge (ESD) damages equipment and impairs electrical circuitry. ESD occurs when printed circuit boards are improperly handled and results in complete or intermittent failures.
The system feature cards and dial shelf controller cards consist of a printed circuit board that is fixed in a metal carrier. Electromagnetic interference (EMI) shielding, connectors, and a handle are integral components of the carrier. Handle the system feature cards and dial shelf controller cards by their carrier edges and handle only; never touch the printed circuit board components or connector pins.
Although the metal carrier helps to protect the printed circuit boards from ESD, wear a preventive antistatic strap whenever handling the dial shelf feature cards or dial shelf controller cards, or router shelf network processing engine, I/O controller, or port adapters. 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.
Cisco recommends the following guidelines to prevent ESD damage:
| Caution Periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms. |

The Cisco AS5800 Universal Access Server supports online insertion and removal (OIR), which allows you to remove and replace a dial shelf controller card or feature card while the system is operating, without affecting system operation.
Each dial shelf controller card and feature card contains female connectors that connect to the system backplane. Each male backplane connector comprises a set of tiered pins, in 3 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 whether to initialize a start-up or shutdown procedure.
Each dial shelf controller card and feature card is designed with two ejector levers to be used when you install or remove a card. The function of the ejector levers (see Figure 9) is to align and securely seat the card connectors in the backplane, and to facilitate the installation and removal process.
Do not force the dial shelf controller cards or feature cards into the slot, as this can damage the card 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 another dial shelf controller card or feature card in the dial shelf.
This section lists tools and parts you need, and explains how to remove and replace a dial shelf controller card in the Cisco 5814 dial shelf chassis.
In most cases, the Cisco 5814 dial shelf chassis is shipped with the dial shelf controller card already installed. When installing your Cisco 5814 dial shelf chassis in a rack, Cisco recommends you first remove all feature cards and dial shelf controller cards to reduce the overall chassis weight.
If your Cisco 5814 dial shelf chassis, feature cards, and dial shelf controller cards have been shipped separately, proceed to the section "Replacing a Dial Shelf Controller Card."
| Caution
If your system is equipped with dual DSCs, Cisco recommends that you perform DSC card replacements during low traffic periods. Use the hw-module <shelf-id>/<slot-num> stop command to stop the backup DSC before you remove the backup (slave) DSC. |
The following parts and tools are required to remove and replace the dial shelf controller card. If you need additional equipment, contact a service representative for ordering information.
If your Cisco AS5800 Universal Access Server is installed in a standard 19-inch, 4-post rack or standard telco rack, cables from other equipment in the rack might obstruct access to the rear of the system. Rack power strips or other permanent fixtures might also cause obstruction.
To ensure easy system access when the Cisco AS5800 Universal Access Server is installed in a rack:
| Caution Dial shelf controller cards weigh 8.5 lb (3.8 kg) each. Use both hands when removing or replacing a dial shelf controller card (see Figure 10). |
| Warning Before working on equipment that is connected to power lines, remove jewelry (including rings, necklaces, and watches). Metal objects will heat up when connected to power and ground and can cause serious burns or weld the metal object to the terminals. |
| Caution
If your system is equipped with dual DSCs, Cisco recommends that you perform DSC card replacements during low traffic periods. Use the hw-module <shelf-id>/<slot-num> stop command to stop the backup DSC before you remove the backup (slave) DSC. |
To remove a dial shelf controller card, complete the following steps:
Step 1 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.
| Caution To prevent ESD damage, handle dial shelf controller cards by ejector levers and carrier edges only, and use an ESD-preventive wrist strap or other grounding device. |
Step 2 Disconnect all cables connected to the dial shelf controller card front panel.
Step 3 Using a number 2 Phillips screwdriver, loosen the 2 panel fasteners on the top and bottom of the dial shelf controller card front panel. (See Figure 9.)
Step 4 Grasp the top and bottom ejector levers (refer to Figure 9) and pull them away from the front panel to disengage the dial shelf controller card from the backplane connectors.
| Caution Do not use the ejector levers as handles to carry the card. They are not designed to support the weight of the card. |
Step 5 Carefully slide the dial shelf controller card partially out of the slot, until you can grasp the card front panel with one hand. Place your other hand under the card to support it. (See Figure 10.)
Step 6 Pull the dial shelf controller card straight out of the slot. Avoid touching the circuitry or any connector pins.
| Caution When inserting or removing the dial shelf controller card, do not use unnecessary force as it can damage the backplane connectors. |
| Caution Never allow anything other than the feature card or dial shelf controller card connectors to make contact with the backplane pins. |
| Caution Never insert any foreign or metallic object into the dial shelf chassis. Also, remove all jewelry and watches prior to placing your hands inside the dial shelf chassis. |
| Caution Dial shelf controller cards weigh 8.5 lb (3.8 kg) each. Use two hands when removing or replacing a dial shelf controller card. (See Figure 10.) |
| Caution
If your system is equipped with dual DSCs, Cisco recommends that you perform DSC card replacements during low traffic periods. Use the hw-module <shelf-id>/<slot-num> stop command to stop the backup DSC before you remove the backup (slave) DSC. |
To replace a dial shelf controller card, complete the following steps:
| Caution Insertion or removal of a second DSC while there is already an active DSC may result in loss of calls. |
Step 1 Ensure your ESD-preventive wrist strap is attached between you and an unpainted chassis surface.
| Caution To prevent ESD damage, handle dial shelf controller cards by ejector levers and carrier edges only, and use an ESD-preventive wrist strap or other grounding device. |
Step 2 Carefully align the dial shelf controller card carrier guides with the top and bottom grooves in the dial shelf slot. Avoid touching the circuitry or any connector pins.
Step 3 Slide the replacement dial shelf controller card into the dial shelf slot until the ejector levers make contact with the chassis frame. (Refer to Figure 10 to orient yourself with the dial shelf and dial shelf controller card.)
| Caution When inserting or removing the dial shelf controller card, do not use unnecessary force as it can damage the backplane connectors. |
Step 4 Seat the dial shelf controller card in the backplane by pushing the card firmly until the ejector levers fold in toward the card front panel, and the front panel is flush with the chassis frame.
Step 5 Using a number 2 Phillips screwdriver, tighten the panel fasteners. This secures the backplane connection and ensures proper EMI shielding.
| Caution Always tighten the panel fasteners on dial shelf controller cards. These fasteners prevent accidental removal and provide proper grounding for the system. |
Step 6 Install a blank filler card (part number DS58-BLANK=) in all empty dial shelf card slots to keep the chassis dust free and to maintain proper air flow.
| Caution To prevent the overheating of internal components, always install blank filler cards in empty slots to maintain the proper flow of cooling air across the cards. |
This completes the steps for removing and replacing a dial shelf controller card. Proceed to the section "Connecting the Cables."
The dial shelf controller card includes a dial shelf interconnect cable to connect the card to the dial shelf interconnect port adapter in the Cisco 7206 router shelf. The connection between the dial shelf controller card and the dial shelf interconnect port adapter uses a single, full-duplex, interconnect cable, as shown in Figure 11.
To connect the dial shelf interconnect cable, complete the following steps:
| Warning Hazardous network voltages are present in WAN ports regardless of whether power to the router is OFF or ON. To avoid electric shock, use caution when working near WAN ports. When detaching cables, detach the end away from the router first. |
Step 1 Attach one end of your interconnect cable to the port labeled "Dial Shelf Interconnect" on the dial shelf controller card front panel. (See Figure 12.)
Step 2 Tighten the jackscrews on either side of the connector.
Step 3 Attach the other end of your cable to the RJ-45 port on the interconnect port adapter in the Cisco 7206 router shelf.
Step 4 Tighten the jackscrews on either side of the connector.
| Caution Never disconnect the interconnect cable while the system is operating (except when replacing a redundant dial shelf controller card) or you will lose all calls. |
| Warning The ports labeled "Network clock," "10BaseT," "Dial Shelf Interconnect," "Console," and "Alarms" are safety extra-low voltage (SELV) circuits. SELV circuits should only be connected to other SELV circuits. Because the E1/T1 circuits are treated like telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV) circuits. |
For more information about the dial shelf interconnect cable and dial shelf interconnect port adapter, refer to the document Cisco AS5800 Universal Access Server Dial Shelf Interconnect Port Adapter Installation and Replacement (Part Number 78-4663-xx).
Verify that your new dial shelf controller card is properly installed and operative by observing the card LEDs as follows:
The Cisco 5814 dial shelf is designed to recognize dial shelf controller cards in specific slots within the dial shelf chassis. The backplane slots numbered 12 and 13 are the designated dial shelf controller card slots. This design supports redundancy features to further eliminate dropped calls.
The following new/modified commands have been added to support redundant DSC equipped systems.
