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.
Caution

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

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

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).

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.

Grounding the Switch
The switch chassis is automatically grounded when you install the switch properly in a grounded rack with
metal-to-metal connections between the switch and rack.
Alternatively, you can ground the chassis (this is required if the rack is not grounded) by attaching a
customer-supplied grounding cable to the chassis grounding pad and the facility ground.
This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the absence
of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician
if you are uncertain that suitable grounding is available. Statement 1024
Warning
When installing or replacing the unit, the ground connection must always be made first and disconnected last.
Statement 1046
Warning
To connect the switch chassis to the facility ground, you need the following tools and materials:
• Grounding lug—A two-holed standard barrel lug that supports up to 6 AWG wire. This lug is supplied
with the accessory kit.
• Grounding screws—Two M4 x 8 mm (metric) pan-head screws. These screws are shipped with the
accessory kit.
•Grounding wire—Not supplied with the accessory kit. This wire should be sized to meet local and national
installation requirements. Depending on the power supply and system, a 12 AWG to 6 AWG copper
conductor is required for U.S. installations. We recommend that you use commercially available 6 AWG
wire. The length of the grounding wire depends on the proximity of the switch to proper grounding
facilities.
• Number 1 manual Phillips-head torque screwdriver.
• Crimping tool to crimp the grounding wire to the grounding lug.
• Wire-stripping tool to remove the insulation from the grounding wire.
Step 1 Use a wire-stripping tool to remove approximately 0.75 in. (19 mm) of the covering from the end of the grounding wire.
Step 2 Insert the stripped end of the grounding wire into the open end of the grounding lug, and use a crimping tool to crimp
the lug to the wire. Verify that the ground wire is securely attached to the grounding lug by attempting to pull the wire
out of the crimped lug.
Step 3 Secure the grounding lug to the chassis grounding pad with two M4 screws, and tighten each screw to 11.5 to 15 in-lb
(1.3 to 1.7 N·m) of torque.
Step 4 Prepare the other end of the grounding wire and connect it to an appropriate grounding point in your site to ensure an
adequate earth ground for the switch. If the rack is fully bonded and grounded, connect the grounding wire, as explained
in the documentation provided by the vendor from whom you bought the rack.

Installing and Removing Fan Modules
This section provides instructions for installing and removing the fan modules for the Cisco MDS 9132T
switch.
You can replace one of the four fan modules even when the switch is operating so long as you perform the
replacement within one minute of removing the old fan module. If you cannot perform the replacement within
one minute, leave the original fan module in the chassis to maintain the designed airflow until you have the
replacement fan module on hand and can perform the replacement.
If you are replacing a module during operations, be sure that the replacement fan module has the correct
direction of airflow, which means that it has the same airflow direction as the other modules in the chassis.
Also, be sure that the airflow direction takes in air from a cold aisle and sends it out to a hot aisle. Otherwise,
the switch can overheat and shut down.
If you are changing the airflow direction of all the modules in the chassis, you must shut down the switch
before replacing all the fan and power supply modules with modules using the other airflow direction. During
operations, all the modules must have the same direction of airflow.

The fan module is designed to be removed and replaced while the system is operating without presenting an
electrical hazard or damaging the system.
The Cisco MDS 9000 Series Switches have internal temperature sensors that can shut down the system if the
temperature within the chassis exceed certain safety thresholds. To accurately monitor the system temperature,
the temperature sensors require sufficient airflow through the chassis. In the event that a fan module is removed
from the chassis and the airflow is reduced, the system will bypass the temperature sensor information and
shut down after five minutes to prevent undetected overheating. However, the switches will shut down sooner
if the major temperature threshold is exceeded.

Removing a Fan Module

While removing the fan module, keep your hands and fingers away from the spinning fan blades. Let
the fan blades completely stop before you remove the fan module. Statement 258
Warning
To remove an existing fan module, follow these steps:
Step 1 On the fan module that you are removing, press the two sides of the fan module handle next to where it connects to the
fan module and pull on the handles enough to unseat it from its connectors.
Step 2 Holding the handle, pull the module out of the chassis.
Do not touch the electrical connectors on the back side of the module and prevent anything else from coming
into contact with and damaging the connectors.
Caution
Step 3 Insert a fan blank module, as shown in Figure 9: Inserted Fan Blank Modules, on page 19 if you do not have a new fan
module.
