Chapter 2 Installing the Cisco MDS 9148S Switch
Installing the Switch in a Cabinet with Insufficient Front Clearance
Installing Front Rack-Mount Brackets for Cabinets with 26 Inches or
Greater of Rail Spacings
The front rack-mount brackets for the Cisco MDS 9148S switch must be installed onto the switch prior
to installing the switch into the cabinet. Follow these steps for cabinets with front-mounting rail to
rear-mounting rail spacings greater or equal to 26 inches:
Step 1
Install the front rack-mount brackets as follows:
a.
Position one of the front rack-mount brackets against the side of the switch and align the screw holes
as shown in
. Then attach the bracket to the switch with the three M4 screws originally
provided with the bracket.
b.
Repeat with the other front-rack mount bracket on the other side of the switch.
Step 2
Install the C brackets as follows:
Note
Two C brackets are shipped preinstalled on the switch, using three M3 screws per bracket. This
installation step is only necessary if the C brackets were removed.
a.
Position one of the C brackets against the side of the switch and align the screw holes. Attach the
bracket to the switch with the three M3 screws originally provided with the bracket.
b.
Repeat with the other C bracket on the other side of the switch.
Installing Front Rack-Mount Brackets for Cabinets with Less Than 26
Inches of Rail Spacings
The front rack-mount brackets for the Cisco MDS 9148S switch must be installed onto the switch prior
to installing the switch into the cabinet. To install brackets for cabinets with front-mounting rail to
rear-mounting rail spacings less than 26 inches that need to be mounted backwards to maintain adequate
fiber-optic clearances, follow these steps:
Step 1
Install the front-rack mount brackets for cabinets with rail-to-rail spacings less than 26 inches as follows:
a.
Position one of the front rack-mount brackets against the side of the switch and align the screw
holes. Then attach the bracket to the switch with two of the three M4 screws originally provided with
the bracket.
b.
Repeat with the other front rack-mount bracket on the other side of the switch.
Note
The front rack-mount bracket does not align with all three holes in the Cisco MDS 9148S switch in this
configuration. The two screws are adequate to hold the weight of the Cisco MDS 9148S switch.
