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 (in the near future). The router shelf supports the dial shelf and performs all routing and packet processing. The router shelf also houses the main system software images.

DC Power Filter Overview

The Cisco AS5800 Universal Access Server is equipped with a passive DC power filter in the dial shelf, which contains a broadband electromagnetic interference (EMI) filter and circuitry for monitoring power coming into the dial shelf. The DC power filter is housed in the filter module, which resides in the dial shelf between the two power entry modules (PEMs).

The DC power filter supports the following functions:

  • DC-input power filtering and power distribution

The filter module first receives -48 VDC power from the PEMs via analog isolation circuits. The DC power passes through a broadband EMI filter in the filter module, then passes to a DC-to-DC converter on the dial shelf controller card, where it is converted and then routed back to the backplane for distribution to the dial shelf feature cards. A single filter module supports a fully configured dial shelf.
  • Maintenance monitoring

The filter module contains the environmental maintenance bus (MBus) module with a logic card, which carries monitor signals throughout the dial shelf by way of two, 10-pin molex MiniFit connectors.

The front and top of the filter module are perforated for minimum air flow restriction. There are no connectors accessible from the front; however, a DB-9 connector at the base of the filter module (visible only from below the dial shelf) connects a monitor cable to an optional AC-input power shelf.

You install the filter module in the Cisco 5814 dial shelf from the rear and plug it directly into the backplane. It is located below a removable rear cover, between the two PEMs, as shown in Figure 3.

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.

  • Disconnect all power and external cables before moving a chassis.

  • 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.

  • A 60-ampere DC circuit breaker is recommended for the input DC power source. This circuit breaker should protect against short-circuit and overcurrent faults in accordance with United States National Electrical Code NFPA 70 (United States), Canadian Electrical Code, part I, C22.1 (Canada), and IEC 364 (other countries).

  • Only a DC power source that complies with the safety extra-low voltage (SELV) requirements in UL1950, CSA 950, EN 60950, and IEC950 can be connected to the DC-input power supply.

  • A readily accessible disconnect device must be incorporated in the fixed wiring.

  • This unit is to be installed in a restricted access area in accordance with articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70.

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 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 ejector levers 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 the 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.

The following guidelines are recommended to prevent ESD damage:

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

  • Handle all system components by their metal carrier edges and handles only; avoid touching the printed circuit board components or any connector pins.

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

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