Using front and
rear mounting
brackets
•
Select an installation position
for the front mounting
brackets as required: near the
power supply side or port
side.
•
Install the rear mounting
brackets based on the rack
depth (distance between the
front and rear rack posts).

If the rack depth is in the
range of 429 to 595 mm
(16.89 to 23.43 in), orient
the rear mounting
brackets with the wide
flange inside the rack.

If the rack depth is in the
range of 274 to 440 mm
(10.79 to 17.32 in) and the
distance from the rear
rack posts to the inner
surface of the cabinet
door is greater than 153
mm (6.02 in), orient the
rear mounting brackets
with the wide flange
outside the rack.
•
If you are to install a
PSR1110-56A power supply,
make sure the rack depth is
larger than 600 mm (23.62 in)
See " Rack-mounting the
switch by using front and
rear mounting brackets
