System Alarm Overview The Trinix system alarm is designed to
monitor various router functions, including operation of fans, chassis
power supplies, on-board power supplies, and primary vs. secondary
Broadlinx board operation. The system alarm is connected to the LED
on the front door of the router and the rear panel “Alarm” BNC con-
nector. The system alarm has two modes: a “secondary” alarm mode,
which illuminates the amber LED on the front door of the router; and a
“primary” alarm mode, which illuminates the red LED on the door. A
jumper on the Broadlinx board is normally set so that both alarm modes
will also enable the rear-panel “Alarm” BNC connector. Additional
information concerning the Trinix system alarm can be found in the
Trinix manual.
Protected path alarms As described above, the protected path web
page will indicate failure/changeover conditions using various colors
and flags. The system alarm can also be triggered according to the selec-
tion made using the alarm pull-down box. Selections are as follows:
• No Alarms - protected path failure/changeover events will not
trigger the system alarm. (Failure/changeover will still be indicated
on the web page).
• Primary - failure/changeover on any primary path will trigger the
system alarm.
• Secondary - failure/changeover on any secondary and primary
path will trigger the system alarm.
• Any Alarm - failure/changeover on any protected path will trigger
the system alarm. This is the default (and recommended) setting.
In the example shown in
, the two yellow flags indicate fail-
ures in two primary paths. Primary path output 4 has failed and the
system is now using secondary path output 260 instead; and, primary
path output 5 has failed and the system is now using secondary path
output 261 instead. Because the alarm pull-down box is set to “sec-
ondary,” the system alarm will not be triggered in this example.
However if one or more secondary paths were to fail, then an amber
LED would seen on the front door; if the jumper described above is in
the default position, an alarm condition would also be present on the
rear panel Alarm BNC connector.
