Installing the T1 or E1 Feature Card
Warning
Do not work on the system or connect or disconnect cables during periods of lightning activity. 
Statement 1001
Warning
The E1 interface card may only be installed in an ACA-permitted customer equipment or a Data 
Terminal Equipment (DTE) that is exempted from ACA’s permit requirements. The customer equipment 
must only be housed in a cabinet that has screw-down lids to stop user access to overvoltages on the 
customer equipment. The customer equipment has circuitry that may have telecommunications 
network voltages on them. 
Statement 90
Warning
The telecommunications lines must be disconnected 1) before unplugging the main power connector 
and/or 2) while the housing is open. 
Statement 89
Note When you replace a feature card in a slot with a new feature card of the same type, the system software 
recognizes the new feature card and brings up the trunk interfaces automatically. If you replace the 
existing feature card with a new feature card of a different type, you must reconfigure the system. For 
configuration details, see the Cisco AS5350XM and Cisco AS5400XM Universal Gateways Software 
Configuration Guide.
To install the T1 or E1 feature card, follow these steps:
Step 1 Attach an ESD-preventive wrist strap.
Step 2 Slide the feature card into the slot until the connector pins make contact with the carrier card backplane 
connector. (See Figure 3-11 and Figure 3-12.)
