Removing an
I/O Module
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.
Swapping I/O
Modules
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 pem
X),
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!
