Dual rack-mount assembly
In order to prepare the GSG units for rack mount installation, the housings needs to be opened,
in order to remove the bottom feet (otherwise the assembly will not fit in a 2U slot.)
DANGER! Do not perform any work on the internal components of a GSG unit,
while the housing is removed, unless you are qualified to do so. Before removing
the cover, unplug the power cord and wait for one minute to allow any capa
citors to discharge.
1.
After making sure that the power cord has been unplugged, carefully turn the first GSG
unit upside down.
2.
Remove the two rear feet . Keep the screws, discard the brackets.
3.
Remove the four housing screws and plugs (if present) at the side panels, and discard
them.
4.
Grip the front panel with one hand, while pushing at the rear with the other hand. Pull
the unit out of its housing.
5.
Remove the four bottom feet from the housing, as shown in the illustration below:
Use a screwdriver or a pair of pliers to remove the springs holding each foot, then push
out the foot.
