1-10 CHAPTER 1: WHAT IS THE LINKBUILDER MSH?
DUA1800-0AAA04
If you have a Management Module installed, you can access
read-only information telling you how the chassis is set up. More
details can be found in the use r guide that accompanies the
Management Module.
For convenience, the display panel may be in stalled into the front
of the MSH chassis (the face of the chassis with cable connections
and module LEDs) or it may be fitted to the back of the chassis i f
you wish to have network connections and cables kept behind
the MSH.
The Thermal Management Unit (TMU)
This is a fan unit which slides into the b ottom of the MSH chassis
and supplies cooling air to the modules by forced circulation. Each
fan has its own failure detector. In the unlikely event of one of the
fans in the unit failing, a Fan Fail LED located on the display panel
at the top of the MSH chassis wi ll light and a message will be sent
to network management stations. If a fan does fail, you should
contact your supplier immediately as the failure may lead to
overheating and subsequent damage to the modules.
Filters fitted over each fan, prevent dust and debris from entering
the chassis. These should be cleaned at regular intervals.
The Cable Support Tray
We recommend that all external cables from the LinkBuilder MSH
are provided with some form of strain relief. The cable support
tray has been specifically designed for use with the M SH chassis.
When fitted, the cable support tray also provides the correct
clearance underneath the unit so that cooling air can freely
circulate.
