Temperature Gauge
The iMediaChassis/20 includes a temperature monitoring gauge with a heat sensor on
the management module. Users define a threshold for chassis temperature via
SNMP. If the chassis’ temperature rises above the specified level, the SNMP agent
sends a trap (configured in iView²) to the administrator. There is also an LED
indicator on the SNMP Management Module for chassis temperature.
User-Replaceable Fans
The iMediaChassis/20 includes two user replaceable fans with tachometers.
Users define a threshold for fan operation via SNMP (when installed in a managed
environment). If a fan’s speed falls below the specified level, SNMP sends a trap
(configured in iView²) to the administrator. There are also two LED indicators on the
SNMP Management Module for fan failure.
Follow these steps when replacing fans:
1) Power down and unplug the chassis,
allowing it to cool down for five minutes.
2) Remove the four screws on the outside
edges of the fan. Save those screws for
securing the new fan.
3) Gently slide out the entire fan assembly
(as shown).
4) Reach into the chassis, through the hole made by removing the
fan, to disconnect the fan’s cable from the chassis’ backplane
connector. Remove the cable from the internal Kurly lock, if
necessary. (Kurly lock shown.)
5) Note the locations of the backplane
connector and the Kurly lock. The new
fan (shown) will be connected/secured
here.
6) Reach into the chassis to connect the
new fan’s cable to the backplane, as the
previous fan was connected. Secure the
cable with the internal Kurly lock.
7) Slide the fan into place and secure it to
the chassis with the four screws.
