- Power Supply module failure.
- Failure in power source (e.g., disconnected power cable).
- Power Supply module is not installed.
Off
Any of the following:
Fan Tray module is not receiving power due to a failure in the module
or the module is not installed correctly.

(Slots 1 and 2) Figure shows unused chassis slots covered by slot covers. The two slots can house an
optional Media Processing Module (MPM) that provides additional digital signaling resources (DSP)
for transcoding sessions. The MPM module occupies two slots.
Note:
The MPM is a separate orderable item.
3
(Slots 3 and 4) SBC CPU AMC module, occupying two chassis slots. The module provides the
following:
Central processing unit (CPU).
RS-232 port interface (
I0I0
) for serial communication.
Reset pinhole button (
//
) for resetting the device (press 1 to 10 seconds) and for restoring
the device to factory defaults (press 15 to 25 seconds).
8 x 1000Base-T Gigabit Ethernet ports for connecting to the IP network. The ports operate in
active-standby pairs, providing 1+1 Ethernet port redundancy. The ports support half- and
full-duplex modes, auto-negotiation, straight-through and crossover cable detection.
The module provides the following LEDs:
Green On
Module in service.
Off
Module out of service.
Green On
Normal operation.
Red On
