To test the module’s data flow, complete the
following steps:
1. Install the DCU module and interface.
When you first install the module in a live,
unlocked chassis, 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, or the chassis is locked, the
status LED will remain red. This is the first
acceptance test.
2. Start the FCS.
Bring up the FOCUS Configuration Software
(FCS), if it is not already running, by clicking
on the FCS program icon .
3. 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 module.
4. Unlock the FOCUS chassis.
If the chassis is locked, execute the “Unlock
Configuration” command on the FCS Setup
menu or click on the “Unlock FOCUS Chassis”
speed button .
This puts the chassis into a configurable state.
It also automatically configures the module to
its default settings.
5. Connect your equipment to the DCU
interface modules.
Plug in the cable that accompanied the Verilink
router from the router to the DCU interface.
Repeast in the second substation..
6. Set the equipment settings.
Power up the Verilink routers and configure
them as follows:
