5U84 Enclosures
CAUTION:
An unpopulated enclosure can weigh up to 46 kg (101 lb). Do not try to lift it by yourself.
CAUTION:
There are three straps tight on the system delivery as shown in Figure 38 “Unpacking the 5U84
Enclosure System ” on page 36. Each strap can weigh up to 55 kg. Hold the straps evenly and lift the
system out of the box with four persons.
CAUTION:
To avoid personal injury, dispose of the lifting straps once the enclosure is installed in the rack. Due to
the weight and size of the enclosure, the lifting straps cannot be reused to remove the enclosure once
it is installed in the rack.
Due to the weight of the enclosure, install it without DDIC installed. It is recommended that remove all
modules in the back to reduce the weight.
The adjustment range of the rail kit, from the inside of the front post to the inside of the rear post is 660 mm -
840 mm. This suits a one metre deep rack within Rack Specification IEC 60297.
1. To facilitate access, remove the door from the rack.
2. Ensure that the pre-assembled rails are at their shortest length.
3. Locate the rail location pins inside the front of the rack and extend the length of the rail assembly to
enable the rear location pins to locate. Ensure that the pins are fully located in the square or round holes
in the rack posts (see Figure 40 “Mounting the System into a Rack (left-hand rail only shown for clarity)”
on page 39).
