22 Netra ct Server Installation Guide • September 2002
Mounting the Chassis in a Rack
Preparing to Lift the Chassis
The Netra ct chassis is shipped out one to four Netra ct servers installed inside. A
fully loaded Netra ct chassis, including the rackmounting brackets, weighs 150
pounds (68.04 kg). If you are going to mount a fully loaded chassis into a rack, you
must use a lifting device, or two people, to lift the chassis.
Alternatively, you can remove all the servers from the chassis to make the chassis
lighter before you mount it in the rack. An empty chassis (with all servers removed)
weighs 74 pounds (33.57 kg).
■
If you want to remove the servers from the chassis before you mount it in the
rack, go to “To Remove the Servers From the Chassis” on page 22.
■
If you want to mount the chassis in the rack without removing the servers, go to
“To Mount the Chassis in a Rack” on page 27.

To Remove the Servers From the Chassis
Note –
Individual Netra ct servers do not comprise an EMI enclosure unless they
are installed in a Netra ct chassis. The chassis does not comprise an EMI enclosure
unless it is full of Netra ct servers and/or blanking panels. If you remove a Netra ct
server, you must install a blanking panel; if you don’t, the unit will be in violation of
47CFR15.
Caution –
If you have a rear-access model Netra ct server, do not attempt to remove
the server from the chassis without first performing the next step or you might
damage certain major system components. Skip to Step 2 only if you have a front-
access model.
1. If you have a rear-access model server, unseat all the rear transition cards from the
server that you are going to remove.
You do not have to completely remove the rear transition cards from the chassis; just
pull them out an inch or two so that they are disengaged from the back of the server
that you are going to remove.
