Preinstallation Guidelines
Airflow Considerations
The switch comes with fan modules and power-supply modules that have either port-side intake or port-side
exhaust airflow for cooling the switch. If you are positioning the port-end of the switch in a cold aisle, make
sure that the switch has a port-side intake fan and power supply modules with red colorings. If you are
positioning the fan and power supply modules in a cold aisle, make sure that the switch has port-side exhaust
fan and power supply modules with blue colorings. All fan modules and power-supply modules must have
the same direction of airflow.
Connection Guidelines for AC-Powered Systems
To connect to the Cisco MDS 9132T switch AC power supplies to the site power source, follow these guidelines:
• Each power supply should have its own dedicated branch circuit.
• Circuits should be sized according to local and national codes.
• The AC power receptacles that are used to plug in the chassis must be the grounding type. The grounding
conductors that connect to the receptacles should connect to protective earth ground in the service
equipment.
Installation Guidelines
Follow these guidelines when installing the Cisco MDS 9132T switch:
• Plan your site configuration and prepare the site before installing the switch. The recommended site
planning tasks are listed in the Site Planning and Maintenance Records section.
• Ensure that there is adequate space around the switch to allow for servicing the switch and for adequate
airflow. The airflow requirements are listed the Technical Specifications section.
• Ensure that you are positioning the switch in a rack so that it takes in cold air from the cold aisle and
sends out air to the hot aisle. For more informatiom, see the Airflow Considerations section.
• Ensure that the air-conditioning meets the heat-dissipation requirements listed in the Technical
Specifications section.
• Ensure that the cabinet or rack meets the requirements listed in the Cabinet and Rack Installation section.
• Ensure that the chassis is adequately grounded. If the switch is not mounted on a grounded rack, we
recommend that you connect both the system ground on the chassis and the site power ground to an earth
ground.
• Ensure that the site power meets the power requirements listed in the Technical Specifications section.
If available, you can use an uninterruptible power supply (UPS) to protect against power failures.
Avoid UPS types that use ferro-resonant technology. These UPS types can become
unstable with systems such as the Cisco MDS 9000 Series, which can in turn
have substantial current draw fluctuations because of fluctuating data traffic
patterns.

Preinstallation Guidelines

• Ensure that circuits are sized according to local and national codes.
For North America, the 650-W power supplies require a 15-A circuit. If you are using a 200 or 240 VAC
power source in North America, the circuit must be protected by a two-pole circuit breaker.
To prevent loss of input power, ensure that the total maximum loads on the circuits
supplying power to the switch are within current ratings for wiring and breakers.
Caution
•As you install and configure the switch, record the information listed in the Site Planning and Maintenance
Records section.
Unpacking and Inspecting the Switch
When handling switch components, wear an ESD strap and handle modules using only the carrier edges. An
ESD socket is provided on the chassis. For an ESD socket to be effective, the chassis must be grounded
through the power cable, the chassis ground, or the metal-to-metal connection with a grounded rack.
Caution
Retain the shipping container in case the chassis has to be shipped in the future.
Tip
The switch is thoroughly inspected before shipment. If any damage occurs during transportation, or if any
item is missing, contact your customer representative immediately. If you purchased Cisco support through
a Cisco reseller, contact the reseller directly. If you purchased support directly from Cisco, contact Cisco
Technical Support.
Note
To inspect the shipment, follow these steps:
1. Compare the shipment to the equipment list provided by your customer service representative and verify
that you have received all items, including the following:
• Grounding lug kit
• Rack-mount kit
• ESD wrist strap
• Cables and connectors
• Optional items, if any, ordered
2. Check for damage and report any discrepancies or damage, to your customer service representative. Have
the following information ready:
• Invoice number of shipper (see packing slip)
• Model and serial number of the damaged unit
• Description of damage

• Effect of damage on the installation
3. Check to be sure that all the power supplies and the fan trays have the expected direction of airflow.
Port-side intake airflow modules have a red coloring, and port-side exhaust airflow modules have blue
coloring. For more information, see the Power Supplies and Fan Modules sections.
Installing the Switch
This section describes how to use the rack-mount kit to install the Cisco MDS 9132T switch into a cabinet or
rack that meets the requirements described in the Cabinet and Rack Requirements 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
the Cisco MDS 9000 Family 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
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
In case of port-side intake airflow, the chassis has to be NEBS compliant. To be NEBS compliant, install the
NEBS kit by following these steps:
1. Install two NEBS rack–mount brackets onto the switch.
2. Install the NEBS air-baffle onto the switch, and ensure that the direction is as shown in the following
images.

NEBS Compliance

Installing the Switch in a 4-Post Rack
To install the switch, you must attach the front and rear mounting brackets to the switch, install the slider rails
on the rear of the rack, slide the switch into the slider rails, and secure the switch to the front of the rack.
Typically, the front of the rack is the side that is easiest to access for maintenance.
Before you begin
• Inspect the switch shipment to ensure that you have everything you ordered.
• Make sure that the switch rack-mount kit includes the following parts:
• Front rack-mount brackets (2)
• Rear rack-mount brackets (2)
• Slider rails (2)
• M4 x 0.7 x 8-mm Phillips countersink screws (12)
• The rack is installed and secured to its location.
Step 1 Install two front-mount brackets to the switch as follows:
1. 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.
2. Position a front-mount bracket so that four of its screw holes are aligned to the screw holes on the side of the chassis.
You can align any four of the holes in the front rack-mount bracket to four of the six screw holes on the
side of the chassis. The holes that you use depend on the requirements of your rack and the amount of
clearance required for interface cables (3 in. [76 mm] minimum) and module handles (1 in. [25 mm]
minimum).

2 & 3. Front rack-mount bracket1 & 4. Four M4 screws
3. Secure the front-mount bracket to the chassis using the four M4 screws and tighten each screw to 12 in-lb (1.36 N·m)
of torque.
4. Repeat Step 1 for the other front rack-mount bracket on the other side of the switch, and be sure to position that
bracket the same distance from the front of the switch.
Step 2 Install the two rear rack-mount brackets on the chassis, as follows:
1. Align the two screw holes on a rear rack-mount bracket to the middle two screw holes in the remaining six screw
holes on a side of the chassis if you are aligning the guide to holes that are near the port connections end of the chassis.
2. Attach the guide to the chassis using two M4 screws. Tighten the screws to 12 in-lb (1.36 N·m) of torque.
3. Repeat Step 2 for the other rear rack-mount bracket on the other side of the switch.
Step 3 If you are not installing the chassis into a grounded rack, you must attach a customer-supplied grounding wire to the
chassis, as explained in Grounding the Switch. However, if you are installing the chassis into a grounded rack, you can
skip this step.
Step 4 Install the slider rails into the rack or cabinet, as follows:
1. Determine which two posts of the rack or cabinet you should use for the slider rails. Of the four vertical posts in the
rack or cabinet, two will be used for the front-mount brackets attached to the easiest-accessed end of the chassis, and
the other two posts will have the slider rails.
2. Position a slider rail at the desired level on the back side of the rack and use two 12-24 screws or two 10-32 screws,
depending on the rack thread type, to attach the posts to the rack. Tighten the 12-24 screws to 30 in-lb (3.39 N·m)
of torque, and tighten the 10-32 screws to 20 in-lb (2.26 N·m) of torque.
3. Repeat Step 3 to attach the other slider rail to the other side of the rack.
To make sure that the slider rails are at the same level, you should use a level tool or tape measure, or carefully count
the screw holes in the vertical mounting posts.
