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 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:

  • Recognize analog pulse code modulation (PCM) bitstreams and convert to digital data

  • Recognize multi-frequency (MF) signaling digits for automatic number identification/dialed number identification service (ANI/DNIS) functions

  • Support Point-to-Point Protocol (PPP) and Serial Line Internet Protocol (SLIP) framing

Figure 1 shows a front view of a fully configured system, and Figure 2 shows a rear view.

Modem Card Overview

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 five LEDs, which indicate modem card status.

Figure 3 shows the modem card components.


Figure 3: Modem Card Components



The modem card performs the following functions:

  • Converts pulse code modulation (PCM) analog bitstreams to digital data.

MICA hex modem modules (HMMs) perform the modulation and demodulation of the analog bitstreams. Each HMM comprises six digital modems. There are 12 HMMs on each modem card; thus, a fully configured dial shelf can support a maximum of 720 modems.
  • Forwards converted and packetized data

The modem card forwards data to the dial shelf main processor, which examines the data and forwards it to the router shelf. From the router shelf, the data is routed to the external network.
  • Supports all modem standards (V.34, V.42bis, and so forth) and features including dial-in and dial-out.

  • Supports online insertion and removal (OIR)

The modem card supports online insertion and removal (OIR), a feature that allows you to remove and replace modem cards while the system is operating. Modem cards can be removed without disruption to the operation of other modem cards and their associated calls. If a modem card is removed while the system is operating, connections or current calls on that card are dropped. Calls being handled by other feature cards, however, are not affected.

Modem cards can be installed in slots numbered slots 0-11on the dial shelf backplane; however, we recommend you install modem cards in dial shelf slots 2 through 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.


Figure 4: Cisco 5814 Dial Shelf with Modem Cards Installed



LED Indicators

The modem card has five LEDs (see Figure 5) to indicate modem card status.


Figure 5: Modem Card Front Panel LEDs



During normal operation, all five LEDs light when the modem card is on. When the modem card CPU software image starts running, it shuts off all LEDs except the power LED. Later, LEDs light again, as listed in Table 1.


Table  1: Modem Card LED Descriptions

PWR Green Power. Lights when card is powered on.
Maint Yellow Maintenance. Lights when there are no active calls on the card, and the you have completed a card-level software busyout. Indicates the card is ready to be removed.
HCPU Green Host CPU/card health. Lights when the modem card passes diagnostics and the modem card CPU is operating properly.
Modems Green Modem health. Lights when all HMMs present have passed diagnostics and are operating properly. Off if one or more HMMs are absent on the card or if one or more modems fails diagnostics.
Calls Green Calls present. Lights when at least one active call is switched through the modem card.

Modem Firmware

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 HMM 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, 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 following modem standards and features:

Online Insertion and Removal

The 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.


Note This section describes the mechanical functions of the system components and emphasizes the importance of following the correct procedures to avoid unnecessary circuit card failures. This section is for background information only. Refer to the section "Removing and Replacing a Modem Card" for specific procedures regarding the modem card.

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 two 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 two ejector levers to be used when you install or remove a card (see 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 this 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.

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.

Telephone Wiring Guidelines

The following guidelines are recommended when working with any equipment that is connected to telephone wiring or to other network cabling:

  • Never install telephone wiring during a lightning storm.

  • Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.

  • Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.

  • Always use caution when installing or modifying telephone lines.

Preventing Electrostatic Discharge Damage

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:

  • Always use an ESD wrist strap or ankle strap when installing or replacing modem cards. Ensure that the ESD strap makes contact with your skin.

  • Handle all system components by their metal carrier edges and ejector levers only; avoid touching the printed circuitry, card components, or any connector pins.

  • Place all system components that have been removed on an antistatic surface with the printed circuit card components facing upward, or in a static shielding bag. If you are returning a feature card to the factory, immediately place it in a static shielding bag.

Caution Periodically check the resistance value of the antistatic strap. The measurement should be within the range of 1 and 10 megohms.

Removing and Replacing a Modem Card

Depending on your configuration requirements, you might need to replace or install new modem cards in your Cisco 5814 dial shelf. The dial shelf contains 14 slots total. Slots 0-11 accept modem cards; however, we recommend you install modem cards in dial shelf slots 2 through 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.)

The OIR feature allows you to install and remove a modem card without turning off system power. Refer to the section "Online Insertion and Removal" for a description of OIR.

To remove a modem card without dropping the calls or connections, you must take the modem card out of service by using the busyout command to busyout 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 following example shows how to busyout the modem card in slot 4 on shelf 5:

router# busyout 5/4
router#

If you are replacing a failed modem card, we recommend you proceed as follows:


  1. Busyout the card

  2. Remove the existing card

  3. Install the new modem card in the same slot

When 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.

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.

The system brings online only interfaces that match the current configuration and were previously configured; all other interfaces require that you configure them with the configure command. For information on using the configure command, refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide that shipped with your system.

Tools and Parts Required

You need the following tools and parts to install the modem card. If you need additional equipment, contact a service representative for ordering information.

  • Modem card (DS58-72DM-CC=)

  • Blank filler card, if needed (DS58-BLANK=)

  • Your own ESD-prevention equipment or the disposable grounding wrist strap included with all upgrade kits, field replaceable units (FRUs), and spares.

  • Cisco AS5800 Universal Access Server Software Installation and Configuration Guide (DOC-AS5800-SICG=)

Removing a Modem Card

To remove a modem card from the Cisco 5814 dial shelf chassis, follow these steps:

Caution Modem cards weigh 8 lb (3.6 kg) each. Use both hands when removing or replacing a trunk card.

Step 1 Note the slot in which the modem card is installed. If you decide to install the new modem card in the same slot, this will hasten the installation process.

Step 2 Initialize the software busyout procedure by entering the following command in privileged EXEC mode:

busyout shelf-number/slot-number

Step 3 Verify the yellow maintenance LED lights on the modem card, which indicates the card is offline and ready to be removed.

Step 4 Attach an ESD-preventive wrist strap between you and an unpainted chassis surface.

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 5 Using a number 2 Phillips screwdriver, loosen the panel fasteners at the top and bottom of the modem card front panel.

Step 6 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.

Figure 6: Using the Ejector Levers



Step 7 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 out of the slot. (See Figure 7.)

Step 8 Pull the modem card straight out of the slot. Avoid touching the circuitry or any connector pins.


Figure 7: Removing and Replacing a Modem Card



Step 9 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."

Replacing a Modem Card

To install the modem card in the Cisco 5814 dial shelf, follow these steps:

Caution Modem cards weigh 8 lb (3.6 kg) each. Use both hands when removing or replacing a trunk card.

Step 1 Ensure your ESD-preventive wrist strap is attached between you and an unpainted chassis surface.

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 Repeat Step 2 through Step 5 for any other modem cards you want to install.

Step 7 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.
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 replacement procedure. Proceed to the section "Verifying and Troubleshooting the Installation."

Verifying and Troubleshooting the Installation

During normal operation, all five 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 Table 1 earlier in this document.

To complete the installation, verify the LEDs operate properly by observing the following LED states on the modem card:

  • The power LED is on.

If the power LED remains off, verify that the card is seated properly.
If the power LED lights on other modem cards in the dial shelf, try inserting the modem card in a different slot. If none of the power LEDs light, check your dial shelf power connections, power entry modules, and AC-input power supplies (if present).
  • The HCPU LED is on.

If the HCPU LED lights, the modem card has passed diagnostics and the system software is up and running.
If the HCPU LED is off but the power LED is on, the software image might have failed to load onto the card. The dial shelf controller will attempt to reload the software automatically. If a programmed number of attempts to reload the software image fails, the dial shelf controller will power OFF the modem card and the HCPU light will shut off.
Verify that other cards in the dial shelf work properly. Verify the card is seated properly. Try inserting the card in a different slot. Verify that you are using the correct software image.
  • The modem LED is on.

If the modem LED lights, all HMMs present on the card pass diagnostics.
If the modem LED fails to light, you have a faulty modem card. Return the modem card to the factory for a replacement.

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."

Configuring the Modems

The Cisco 5814 dial shelf is designed to recognize modem cards in slots 0-11 within the dial shelf chassis.We recommend you install modem cards in slots 2 through 11, and reserve slots 0 and 1 for trunk cards, because the trunk card clocks can only operate in slots 0 through 5.

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.

If you are replacing a modem card in a different slot from the one you just removed, additional configuration is needed. Refer to the Cisco AS5800 Universal Access Server Software Installation and Configuration Guide to configure modems.
