Refer to Figure 4-3 and proceed as follows to install the SEH into a
19-inch rack.
1. Remove the four cover screws (two from each side) located along the

provided in the rackmount kit, attach the rack mounting brackets to
each side of the SEH.

3. Ensure that the rack used will support the unit, and that the rack will
remain stable with the unit installed in it. Support the SEH securely
from underneath, and align the mounting brackets of the SEH chassis
with the screw holes in the equipment rack as shown in Figure 4-4.
Fasten the SEH to the equipment rack securely.
Do not remove the cover from the SEH. Do not remove any
other screws from the unit.
!
CAUTION
The cooling fans at the rear panel of the SEH must have
adequate clearance (two inches on either side and in the
rear) for unrestricted air flow. The temperature for the selected
location must be maintained between 5°C and 40°C, and
fluctuate less than 10°C per hour.
