Use the following steps to remove an I/O module:

CAUTION: The modules are not hot-swappable. Power off the unit

before installing, removing, or exchanging the modules. Failure to

do so could damage the modules.

1 Remove the AC power cord from the back of the RAS 1500 or RAS 1500

Expansion to power off the unit.

WARNING: Remove the telephone cables from the module before you

remove the module from the unit. Failure to do so could result in electric

shock.

2 Remove the telephone cables from the I/O module.

3 Loosen the two screws on the I/O module.

4 Place the screwdriver provided with the RAS 1500 in the small hole

beneath the I/O module's slot and push until the module ejects out of

place.

5 Remove the I/O module from the slot.

6 If you are not replacing the I/O module, you must install a blank face

plate.

Leaving the I/O slot open presents a potential safety hazard and the unit

may no longer meet FCC requirements.

If you swap a Basic Rate Interface (BRI) I/O module and analog I/O

module, reset the modem's settings. Otherwise, ports could hang. Two

examples are provided below. Be sure to provide the proper interface

(rm0, pem0, or pemX), slot (slot:1 or slot:2), and port numbers.

To reset an analog modem's configuration to the factory-default settings,

use the following CLI command:

set switched interface rm0/slot:1/mod:1 at_command AT&F0&W

To reset an ISDN modem's configuration to the factory-default settings,

use the following CLI commands:

set switched interface rm0/slot:1/mod:1 at_command AT&F0&W

set switched interface rm0/slot:1/mod:1 at_command ATZ!
