4.4.5 Electrical Transceiver Module
Testing
(For complete instructions on specific FCS proce-
dures, please refer to the FCS online help facility.)
To test the Transceiver Module’s functionality,
complete the following steps:
1. Set up the chassis and other modules.
Set up the test chassis and all other channel
modules, per your application. Do not connect
the chassis to another.
2. Install the Transceiver Module.
Insert the Transceiver Module into the chassis
according to the instructions in the
“Installation” section earlier in this chapter.
3. Energize the chassis.
Energize the FOCUS chassis by applying
power.
When you first energize the chassis, and thus
the Transceiver Module, the red/green status
LED is red. If the module is functional, the
status LED turns green within 20 seconds. If
the module is non-functional, the status LED
stays red, even after 20 seconds have elapsed.
This is the first acceptance test.
At this time, the two lower red LEDs
(SIGNAL-1 and SIGNAL-2) should be lit to
indicate that no signal is being received in a
dual module. (Note that a single DS1 Module
will only have the SIGNAL-1 LED on.)
4. Connect a PC with the FCS installed.
Connect an RS-232 cable from a PC that has
the FOCUS Configuration Software (FCS)
installed to the RS-232 interface on the front
of the chassis’ Maintenance Module.
5. Start the FCS.
Bring up the FOCUS Configuration Software
(FCS), if it is not already running, by clicking
on the FCS program icon .
6. Bring the FOCUS chassis “on line”.
Click on the “Online” speed button
.
This uploads to the FCS the current status,
settings, operating statistics, etc., for the
FOCUS chassis — and the DS1 Transceiver
Module.
7. Unlock the FOCUS chassis.
If the chassis is locked, execute the “Unlock
Configuration” command on the FCS Test
menu or click on the “Unlock FOCUS
Chassis” speed button .
4.4.6 Optical Transceiver Module
Testing
(For complete instructions on specific FCS proce-
dures, please refer to the FCS online help facility.)
To test the Optical Transceiver Module’s basic
functionality, complete the following steps:
This test applies to both versions of the Optical
Transceiver Module (i.e., with and without the
four-fiber hot standby).
1. Set up the chassis and other modules.
Set up the test chassis and all other channel
modules, per your application. Do not connect
the chassis to another.
2. Install the Optical Transceiver Module.
Insert the Optical Transceiver Module into the
chassis according to the instructions in the
“Installation” section earlier in this chapter.
3. Energize the chassis.
Energize the FOCUS chassis by applying
power.
When you first energize the chassis, and thus
the Optical Transceiver Module, the red/green
status LED is red. If the module is functional,
