Installing the Switch
This section describes how to use the rack-mount kit to install the Cisco MDS 9220i switch into a cabinet or
rack that meets the requirements that are described in the
section.
Installing the Switch on Shelf Brackets
This section provides general instructions for installing the switch on top of the shelf brackets. Note that this
is an optional task.
Before you install, operate, or service the system, refer to
Regulatory Compliance and Safety Information for
for important safety information.
Note
To install the switch on top of the shelf brackets, follow these steps:
Step 1
Verify that the shelf brackets are level and securely attached to the rack-mounting posts, the crossbar is securely attached
to the shelf brackets, and the rack is stabilized.
Step 2
Slide the switch onto the shelf brackets, ensuring that it is squarely positioned.
Step 3
Attach the switch to the rack-mounting posts.
We recommend that you ground the chassis even if the rack is already grounded. A grounding pad with two
threaded M4 holes is provided on the chassis for attaching a grounding lug.
Caution
For switches installing in the USA, the grounding lug must be NRTL listed and compatible with copper
conductors. Only copper conductors (wires) must be used and these conductors must comply with National
Electrical Code (NEC) for ampacity.
Note
NEBS Compliance
Network Equipment Building System (NEBS) is a USA standard for telecommunications equipment safety
and reliability. In the case of port-side intake airflow the system must be NEBS compliant. To be NEBS
compliant, install the NEBS kit by following these steps:
1.
Install two front rack–mount brackets onto the switch.
a.
Determine which end of the chassis is to be located in the cold aisle as follows:
• If the switch has port-side intake modules (fan modules with red coloring), position the switch
so that its ports are in the cold aisle.
• If the switch has port-side exhaust modules (fan modules with blue coloring), position the switch
so that its fan and power-supply modules are in the cold aisle.
