This chapter includes the following sections:
The Cisco AS5400 universal access server is a versatile data communications platform that provides high performance, high density, and, online insertion and removal of dial feature cards. 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.
The chassis consists of the following components:
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 high density 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. For easy access to connectors on the DFCs, avoid stacking DFCs with connectors vertically above each other.
In any single slot on the DFC carrier card, you can install your choice of:
All DFCs on the Cisco AS5400 chassis support online insertion and removal (also known as hot swapping). You can install, remove, replace, and rearrange the DFCs without turning off the chassis power.
When the chassis detects that a DFC is installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the DFC, and resumes chassis operation without any operator intervention.
Refer to:
 |
Caution The carrier cards that carry the DFCs are not hot swappable. You must power down the system before removing a carrier card. |
Use the power switch on the chassis to power down the chassis.
 |
Warning Before working on a chassis or working near power supplies, unplug the power cord on the AC units; disconnect the power at the circuit breaker on DC units. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
For DC powered units:
|
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure that all power is off, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
|
Caution Before you remove a carrier card, read Chapter 1, "Safety warnings, Recommendations and Tools required." |
To remove a populated carrier card after you power down the chassis, follow the steps below:
|
Warning Before opening the chassis, disconnect the telephone-network cables to avoid contact with telephone-network voltages. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
|
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. To see translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document that accompanied this device. |
Step 2 Disconnect all interface cables from the DFC and secure them out of the way.
 |
Note Use the DFC handles to remove the carrier card. Ensure that the DFCs are secured to the carrier card. |
Step 3 Grasp the DFC handles and gently pull towards you to guide the carrier card out of the slot. Place one hand under the carrier card as you pull it out of the chassis.
Step 4 After you remove the carrier card out of the chassis, set it aside on an ESD-preventive mat.
Step 5 If a DFC slot on the carrier card is to remain empty, install a blank cover over the open DFC slot to ensure proper airflow inside the chassis.
To install a populated carrier card:
Step 2 Align the captive screws with their holes, and then seat the card completely.
Step 3 Tighten the two captive screws to secure the carrier card to the chassis.
Step 4 If the carrier card has a blank DFC slot, install a blank cover over the open DFC slot to ensure proper airflow inside the chassis.
Step 5 For AC powered units, reconnect the AC power cord.
Step 6 For DC powered units, remove the tape from the circuit breaker switch handle, and reinstate power by moving the handle of the circuit breaker to the ON position.
