the module is functional and red if the module is
non-functional. The RX and TX LEDs are momen-
tarily illuminated when the module is receiving or
transmitting data respectively.
26.4 Acceptance Test
As noted earlier, we recommend that you initially
install and test the 6NR/6NV module and interface
in a “test” chassis (i.e., one that is not part of an
operating network). This way, you can quickly
perform the acceptance test without interfering
with a live network.
To test the data flow through the 6NR/6NV
Module, we recommend using the Fireberd Model
6001 or the Lynx Digital Network Tester and their
accompanying cables along with a 6NR/6NV
interface. You will need:
•Two FOCUS chassis
•2 6NR/6NV interfaces
To test the module’s data flow, complete the
following steps:
1. Install the 6NR/6NV 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
