18.4.1 Status Indicators
The module has three status indicators, as shown
in Figure 18-2. The Red/Green status LED is
green if the module is functional and red if the
module is non-functional. The TX green LED,
when lit, indicates that the module is transmitting
data. The RX green LED, when lit, indicates that
the module is receiving data.
18.5 Acceptance Test
As noted earlier, we recommend that you initially
install and test the 64K 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 High Speed Data
(64K/64V/64R) Module with the electrical
interface, we recommend using the Fireberd
Model 6001 or the Lynx Digital Network Tester.
To test the optical interface, we recommend using
ABB’s REL350 Relay equipped with an optical
adapter.
To test the 64K module’s data flow, complete the
following steps:
1. Install the 64K module and interface.
If the module and interface have not been
installed, do so now following the instructions
in the “Installation” section earlier in this
chapter.
When you first install the 64K 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, the status LED
stays red, even after 20 seconds have elapsed.
This is the first acceptance test.
