Critical threshold
—
The
board is powered-down
when the CPU sensor hits
this limit. No syslog will be
generated here.
Warning
threshold
—
When this limit
is reached, a syslog is
generated. The board
automatically powers on,
when the CPU temperature
decreases.
Syslog threshold
—
When
this limit is reached, a
syslog is generated, which
alerts that the
board-auto-shutdown is
enabled.
Only CPU

External Connections and Chassis Cable Ports
When connecting the router internal ports to external cables or exterior devices, you must thread the router
cables through the chassis cable ports designated for this purpose. Some chassis ports are reserved for specific
cables and remaining ports can be used based on your network configuration and cabling requirements.
When you make router cable connections through these ports, you must use cable glands as described in
Using Cable Glands, on page 58
, to protect the router interior from environmental elements, including
moisture, heat, cold, and dust. Failure to use cable glands with the chassis cable ports can result in damage
to the router.
Note
The cable connectivity can be provided as follows:
•
The power entry is provided on the extreme right of the bottom panel, which is through a DC connector
for DC (FD chassis). Use an outdoor-rated DC cable that can be routed through the DC connector. For
AC inputs (on a FA chassis), use a special IP-65 compliant AC connector. The AC or DC input cable
can be removed from the router without opening the router cover.
•
Each SFP port can be connected with an LC-LC patch cable from the SFP module to the faceplate. For
external connectivity, an LC cable system a with IP-65 sealing should be used.
