Cisco AS5800 Universal Access Server Overview

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.

Dial Shelf Interconnect Port Adapter Overview

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.

LED Indicators

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.


Figure 3: Dial Shelf Interconnect Port Adapter Front Panel


The following conditions must be met before the dial shelf interconnect port adapter is enabled:

  • The dial shelf interconnect port adapter must be correctly connected to the router shelf midplane and receiving power.

  • A valid Cisco IOS software image for the adapter has been downloaded successfully.

  • The system recognizes the adapter.

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.

Receptacles and Cables

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.


Figure 4: Dial Shelf Interconnect Cable with Jackscrew Connectors


Software and Hardware Requirements

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.


Note IOS release 11.3 (5.1) AA or later is required to support two dial shelf interconnect port adapters. Two dial shelf interconnect port adapters are required to support dual dial shelf controllers.

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.

Safety Guidelines

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:

  • Locate the emergency power-off switch for the room in which you are working before beginning any procedures requiring access to the chassis interior.

  • Never work alone when potentially hazardous conditions exist.

  • Never assume that power has been disconnected from a circuit; always check.

  • Never perform any action that creates a potential hazard to people or makes the equipment unsafe.

  • Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.

Preventing Electrostatic Discharge Damage

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:

  • Always use an ESD wrist or ankle strap and ensure that it makes good skin contact.

  • Connect the equipment end of the strap to an unfinished chassis surface.

  • When installing a component, use any available ejector levers or captive installation screws to properly seat the bus connectors in the backplane or midplane. These devices prevent accidental removal, provide proper grounding for the system, and help to ensure that bus connectors are properly seated.

  • When removing a component, use any available ejector levers or captive installation screws to release the bus connectors from the backplane or midplane.

  • Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

  • Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.

  • Avoid contact between the printed circuit boards and clothing. The wrist strap only protects components from ESD voltages on the body; ESD voltages on clothing can still cause damage.

  • Never attempt to remove the printed circuit board from the metal carrier.

Caution For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.

Removing and Replacing the Dial Shelf Interconnect Port Adapter

Depending on your circumstances, you might need to install a new dial shelf interconnect port adapter in a Cisco 7206 router shelf or replace a failed adapter. In either case, no installation tools are necessary; the dial shelf interconnect port adapter connects directly to the router midplane and locks into position by a port adapter lever. The dial shelf interconnect port adapter has no configurable ports.

The Cisco 7206 router shelf supports OIR; however, unless you have installed a second dial shelf interconnect port adapter and established a redundant connection to the dial shelf, you must either reload the entire system software after removing and replacing a dial shelf interconnect port adapter in an operating system, or you must power off the system during the replacement procedure.

You reload the system software at the router shelf console using the reload command. For a detailed description of the reload command, refer to the Configuration Fundamentals Command Reference publication available on the documentation CD-ROM that shipped with your system.


Note When you reload the software, all active calls are lost; any new incoming calls occurring during the reload process are not accepted.

If you power off and restart the system, the system software automatically reboots. For instructions on powering off and powering on the access server, refer to the Cisco AS5800 Universal Access Server Hardware Installation and Configuration Guide that shipped with your system.

Tools and Parts Required

You need the following equipment and parts to install the dial shelf interconnect port adapter. If you need additional equipment, contact a service representative for ordering information.

  • Dial shelf interconnect port adapter (PA-DSIC=)

  • Dial shelf interconnect cable(s) (CAB-DSIC-5= or CAB-DSIC-20=)

  • Blank port adapter, if needed, for unoccupied slots (MAS-72BLANK=)

  • Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, FRUs, and spares

  • An antistatic mat and/or an antistatic shipping container


Note When an adapter slot is not in use, a blank adapter must fill the empty slot to allow the router shelf to conform to EMI emissions requirements and to allow proper air flow across the adapters.

Removing the Dial Shelf Interconnect Port Adapter

Use the following procedure to remove the dial shelf interconnect port adapter from the Cisco 7206 router shelf:

Step 1 Attach an ESD-preventive wrist strap between you and an unfinished chassis surface.

Step 4 Slide the interconnect port adapter into the slot until the connectors are properly seated in the midplane.

Step 5 Place the adapter lever in the locked position, as shown in Figure 5.


Note If the adapter lever does not move to the locked position, the adapter is not completely seated in the midplane. Carefully pull the adapter half way out of the slot, reinsert it, and place the lever in the locked position.

This completes the procedure for installing a new dial shelf interconnect port adapter in the Cisco 7206 router shelf. Proceed to the section "Attaching the Dial Shelf Interconnect Cable."

Attaching the Dial Shelf Interconnect Cable

The interconnect port adapter provides a single dial shelf interconnect receptacle. For a redundant connection to the dial shelf, you need to install a second port adapter.

Caution Do not use the dial shelf interconnect port adapter for any outgoing WAN connections.

Connect the dial shelf interconnect cable as follows:

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.)


Figure 8: Connecting the Dial Shelf Interconnect Cable


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."

Verifying and Troubleshooting the Installation

To complete the installation, verify the LEDs operate properly by observing the following LED states on the dial shelf interconnect port adapter:

  • The power enabled LED is on.

If the enabled LED is off, suspect that the interconnect port adapter has pulled away from the midplane. Reseat the interconnect port adapter in its slot.
If the enabled LED remains off, contact a service representative for assistance.
  • The link LED is on.

If the link LED is off, check the interconnect cable connection and tighten the jackscrews.
  • You can also use the show dsi command in EXEC mode to display information about the dial shelf interconnect port adapter.

This completes the dial shelf interconnect port adapter installation. Refer to the Cisco 7206 Installation and Configuration Guide that shipped with your router shelf for hardware troubleshooting procedures. Refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide that shipped with your Cisco AS5800 Universal Access Server for software verification, configuration procedures, and examples.
