This section explains some common maintenance procedures.
2.1 Replace an Interface Module (Hot Swap)
Interface Modules can be removed and replaced without shutting the system down.
Interface Modules must be replaced with the same type of card.
To perform a “hot swap” of an Interface Module:
1. From the Operator’s Console, select F2,
Port Card Status
. Display the port card
to be swapped, so you can monitor its status during the process.
2. On the card to be replaced, move the
Normal/Disable
switch to the
Disable
position. This locks the card and disables the Base Stations to prevent new calls
from starting, but does not drop active calls. Existing calls are allowed to
complete before the card is locked.
3. When the alarm light stops blinking and turns solid red, the card is idle. Verify
this on the Operator’s Console, all lines and Base Stations should show no
activity. If you unplug the card before it is idle, the system may alarm.
4. At the Operator’s Console, press ESC. This stops the Operator’s Console from
trying to monitor the card you are about to remove.
5. Unplug the 25 pair cable from the card.
6. Unscrew the card from the shelf and slide it out.
7. Slide the replacement Interface Module into the slot, until the card clicks into
place. Tighten the screws at the top and bottom of the card to secure it.
8. Connect the 25 pair cable to the card.
9. When the heartbeat LED sequence displays on the Interface Module (LED 1
flashes 1/3 of the time), select
F2
on the Operator’s Console to verify the status of
the new card. It should be
Running
.
