Feature Card and Carrier Card Guidelines
This chapter includes the following sections:
•Online Insertion and Removal of Feature Cards
•Removing and Installing Populated Carrier Cards
•Where to Go Next
Cisco AS5350XM Chassis
The Cisco AS5350XM universal gateway chassis has a motherboard, a high-speed backplane, and three slots for feature cards that allow online insertion and removal (OIR).
Cisco AS5400XM Chassis
The Cisco AS5400XM universal gateway chassis has a motherboard, a high-speed backplane, and seven slots for feature cards that allow OIR.
Each feature card is a 5.1- by 13-inch (13- by 30-cm) PCI-based interface board.
The following trunk types are supported:
•T1 feature card—Supports North American robbed-bit signaling (RBS) on T1 trunks, including a variety of North American RBS protocol, framing, and encoding types.
•E1 feature card—Supports channel-associated signaling (CAS) for E1 trunks, with R2 signaling. Many countries require an E1 R2 variant. Per-country defaults are provided for supervisory and inter-register signaling.
•Channelized T3 (CT3) feature card—Provides physical line termination for a channelized T3 ingress trunk line, and uses an onboard multiplexer to multiplex 28 channelized T1 lines into a single channelized T3 line.
The following access types are supported:
•Universal port feature card—Converts voice, fax, and dial calls into IP packets or frames by using the Nextport digital signal processor (DSP) modules.
•Dial-only feature card—Converts dial calls into IP packets or frames by using the Nextport digital signal processor (DSP) modules.
•Voice feature card—Converts voice and fax calls into IP packets or frames by using packet fax or voice digital signal processor (DSP) modules (PVDM2).
Online Insertion and Removal of Feature Cards
All feature cards on the Cisco AS5350XM and Cisco AS5400XM chassis support OIR (also known as hot swapping). You can install, remove, replace, and rearrange the feature cards without turning off the chassis power.
When the chassis detects that a feature card is installed or removed, it automatically runs diagnostic and discovery routines, acknowledges the presence or absence of the feature card, and resumes chassis operation without any operator intervention.
See the following chapters for more information about specific feature cards:
•See Chapter 3, "T1 and E1 Feature Cards," to perform OIR of the T1 or E1 feature card.
•See Chapter 4, "Channelized T3 Feature Card," to perform OIR of the CT3 feature card.
•See Chapter 5, "Universal Port and Dial-Only Feature Cards," to perform OIR of the universal port or dial-only feature card.
•See Chapter 6, "Voice Feature Card," to perform OIR of the voice feature card.
Removing and Installing Populated Carrier Cards
The carrier cards that carry the feature cards are not hot-swappable. Removing a card while the system is still powered on may cause permanent damage to electronic circuits on the card.
The feature card carrier card plugs into one of the backplane slots and supports two feature cards. The carrier card increases backplane capacity and allows OIR of the feature cards. (See Figure 2-1.)

Warning Before working on a chassis or working near power supplies, unplug the power cord on AC units; disconnect the power at the circuit breaker on DC units. Statement 12
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit. Statement 1003
Warning Before connecting or disconnecting ground or power wires to the chassis, 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. Statement 140
Removing a Populated Carrier Card
Warning Before opening the unit, disconnect the telephone-network cables to avoid contact with telephone-network voltages. Statement 1041
Warning Do not work on the system or connect or disconnect cables during periods of lightning activity. Statement 1001
To remove a populated carrier card, follow the steps below:
Step 1 Power down the chassis.
Step 2 Disconnect all interface cables from the universal gateway, and secure them out of the way.
Step 3 Loosen the two captive screws that secure the carrier card to the chassis until each screw is free of the chassis. (See Figure 2-2 and Figure 2-3.)

Figure 2-3 Loosening the Captive Screws on the Cisco AS5400XM
Step 4 Grasp the feature card handles and gently pull them toward 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. (See Figure 2-4 and Figure 2-5.)
Note Use the feature card handles to remove the carrier card. Ensure that the feature cards are secured to the carrier card.

Step 5 After you remove the carrier card from the chassis, set it aside on an ESD-preventive mat.
Step 6 If the backplane slot is to remain empty, install a blank cover over the open slot to ensure proper airflow inside the chassis. (See Figure 2-6.)

Installing a Populated Carrier Card
To install a populated carrier card:
Step 1 Slide the carrier card into the slot until it touches the backplane connector. (See Figure 2-7 and Figure 2-8.)

Figure 2-8 Installing the Carrier Card in the Cisco AS5400XM
Step 2 Align the captive screws with their holes, and seat the card completely.
Step 3 Tighten the two captive screws to secure the carrier card to the chassis. (See Figure 2-9 and Figure 2-10.)

Figure 2-10 Tightening the Captive Screws on the Cisco AS5400XM
Step 4 If the carrier card has a blank feature card slot, install a blank cover over the open feature card slot to ensure proper airflow inside the chassis. (See Figure 2-11.)

Step 5 For AC-powered units, reconnect the AC power cord. 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. For more information about the AC and DC power supplies, see the chassis installation guide for your universal gateway.
Step 6 Reconnect all interface cables.
