Overview

This chapter provides an overview of the Cisco AS5400 universal access server, a versatile data communications platform that provides high performance, high density, and hot swappability in only two rack units. The Cisco AS5400 supports dial and unified communications on the same platform without any loss of performance.

The Cisco AS5400 is intended for large companies and service providers who require dense and scalable solutions to create new multi-service access networks, replace existing access server hardware, or expand and enhance their current access offering. The Cisco AS5400 provides you with a cost effective platform for deploying the widest range of IP based services.

This chapter includes the following sections:

Chassis Components

The chassis consists of the following components:

One modular chassis with motherboard, high-speed backplane and seven DFC slots. The DFCs are as follows:
- AS54-DFC-8CT1/CE1 (8PRI CT1/CE1) card
- AS54-DFC-108NP card
- AS54-DFC-CT3 card
Building Integrated Timing System (BITS) interface port
Two Fast Ethernet (2FE) LAN ports
Two T serial ports for backhaul WAN support
One fast console port for local administrative access
An integral redundant AC or DC power supply, with two power input lines.

Dial Feature Cards (DFCs)

The Dial Feature Card (DFC) is a 5.1 by 13 inch PCI based interface board that allows online insertion and removal (OIR) of trunk ingress, and modem cards without rebooting or powering off the system.

The chassis includes three backplane slots and each slot accepts one DFC carrier card. Each DFC carrier card accepts two DFCs which allow OIR. The motherboard accepts one DFC in its own dedicated slot.

In any single slot on the DFC carrier card, you can install your choice of:

AS54-DFC-8CT1/CE1 (8PRI CT1/CE1), see Figure 1-3
AS54-DFC-CT3, see Figure 1-4
AS54-DFC-108NP, see Figure 1-5

Note For details on cards, installation, and troubleshooting, see the Cisco AS5400 Universal Access Server Card Installation Guide.

AS54-DFC-8CT1/CE1 (8PRI CT1/CE1)

You can install an AS54-DFC-8CT1 or AS54-DFC-8CE1 card in any carrier slot of the access server chassis. This card provides an interface for eight RJ-45 T1 or E1 PRI ports through a special cable.

Note You need a special cable for eight RJ-45 T1 or E1 PRI ports to eight female RJ-45 receptacles. Refer to "AS54-DFC-8CT1/CE1 Interface Cable and Port Pinouts" section.

An AS54-DFC-8CT1 provides physical line termination for up to 192 (8CT1) and 248 (8CE1) DS0 channels and uses onboard HDLC controllers to terminate digital (ISDN) calls. You can use the bantam jacks on the card to monitor a line.

Figure 1-3: AS54-DFC-8CT1/CE1

The T1 ports are configured at 100-ohms per port. For the AS54-DFC-8CE1 card, the eight ports can be configured as 75- or 120-ohm lines. The factory-set default is 120-ohm. To choose input impedence for the AS54-DFC-8CE1 ports, use a software command to change the impedance. For information on software commands, see the Cisco AS5400 Universal Access Server Card Installation Guide for details.

Cable specifications and port pinouts are listed in Appendix C, "Cabling Specifications."

AS54-DFC-CT3 (CT3 DFC)

You can install an AS54-DFC-CT3 in any carrier slot of the access server chassis.

Figure 1-4: AS54-DFC-CT3

An AS54-DFC-CT3 provides physical line termination for a channelized T3 ingress trunk line. It uses an onboard multiplexer to multiplex 28 channelized T1 lines into a single channelized T3 line.

An AS54-DFC-CT3 provides physical line termination for up to 672 DS0 channels and uses onboard HDLC controllers to terminate digital (ISDN) calls up to 248 DS0 channels. You can use the bantam jacks on the DFC to monitor a line or test any one of the individual circuits in drop and insert mode.

AS54-DFC-108NP (108NP DFC)

You can install an AS54-DFC-108NP in any carrier slot of the access server chassis.

Figure 1-5: AS54-DFC-108NP

An AS54-DFC-108NP provides 108 port sessions for modem applications. Each session is capable of originating or terminating a data session over a DS0 in PCM serial data format.

Power Supply

The power system is comprised of a fully redundant switching power supply with two AC (or DC) inputs to the main power modules. Each input, and output, is 100% fully redundant, with dual fans for added reliability.

The output of each power module is rated at 300 watts (nonredundant mode), and is composed of four independent output voltages: 3.3V, 5V, 12V and -12V. AC input units have power factor correction, and low harmonic distortion. Units which are in redundant mode run at one-half the power capability. If a power supply failure occurs, these units are capable of powering the complete system either at the input side or the DC load side. Power failures are reported through environmental monitoring software.
