The interconnect port adapter installs in the router shelf and connects to the dial shelf via a full-duplex, 100-Mbps interconnect cable.
This document provides instructions for removing and replacing the interconnect port adapter and explains how to attach the interconnect cable between the router shelf and the dial 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 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. 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, and Figure 2 shows a rear view.


The Cisco AS5800 Universal Access Server includes a dial shelf interconnect port adapter that connects the Cisco 5814 dial shelf to the Cisco 7206 router shelf. The interconnect port adapter installs in any 7206 router shelf port adapter slot and connects directly to the dial shelf controller card on the dial shelf via a single, full-duplex cable.
The interconnect port adapter allows data transfers between the dial shelf and the router shelf. Data is converted into packets by the feature cards, transmitted to a hub on the dial shelf controller card, and from there sent to the router shelf. Conversely, packets from the router shelf are sent to the dial shelf controller card, where they are transmitted over the backplane to the modem and trunk cards.
The dial shelf interconnect port adapter contains two LEDs: an enabled LED and a link status LED, shown in Figure 3. After system initialization, the enabled LED lights to indicate that the dial shelf interconnect port adapter has been enabled for operation.

The following conditions must be met before the dial shelf interconnect port adapter is enabled:
If any of the above conditions are not met, or initialization fails for other reasons, the enabled LED will remain off.
The link status LED indicates an active connection to the dial shelf. This LED lights when the dial shelf interconnect port adapter is receiving a carrier signal from the dial shelf.
The dial shelf interconnect port adapter contains a single RJ-45 receptacle, which is used to connect the router shelf to the dial shelf. The cable used for this connection is a Cisco proprietary cable, customized with jackscrews to secure the connection. You must use this specially designed cable that shipped with your dial shelf interconnect port adapter to connect the dial shelf to the router shelf.
| Caution Disconnecting this cable while the system is operating will result in a loss of all calls. |
Figure 4 shows the dial shelf interconnect cable with jackscrew connectors.

The dial shelf interconnect port adapter requires that the host Cisco 7206 router shelf is running Cisco IOS Release 11.3(2) AA or later.
Port adapters are rated by data-carrying capacity as either high, medium, or low bandwidth. The host Cisco 7206 router shelf has certain data carrying capacity (or bandwidth) restrictions that affect the number of high bandwidth port adapters you can install. The dial shelf interconnect port adapter is considered to be high bandwidth. Refer to the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines document that shipped with your Cisco 7206 router shelf for more information on port adapter installation restrictions.
This section provides safety and ESD-prevention guidelines to help you avoid injury to yourself and avoid damage to the equipment. The following safety guidelines are recommended when working with any equipment that connects to electrical power or telephone wiring:
Electrostatic discharge (ESD) damage, which can occur when electronic cards or components are improperly handled, results in complete or intermittent failures. Port adapters and processor modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps to protect the board from ESD, use a preventive antistatic strap during handling.
Following are guidelines for preventing ESD damage:
| Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms. |

Step 1 Attach the interconnect cable directly to the RJ-45 port on the interconnect port adapter.
Step 2 Tighten the jackscrews on either side of the connector.
Step 3 Attach the other end of your interconnect cable to the port labeled "Dial Shelf Interconnect" on the Cisco 5814 dial shelf controller card. (See Figure 8.)

| 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 |
Step 4 Tighten the jackscrews on either side of the connector.
Step 5 Reload the system software using the reload command in EXEC mode, or restart the access server to reboot the system software.
This completes the dial shelf interconnect cable installation procedure. To verify the installation, proceed to the section "Verifying and Troubleshooting the Installation."
