For instructions on installing the switch using the rack-mount kit shipped with the switch, see the
“Installing the Chassis in a Cabinet or Rack” section on page 2-5.
For instructions on installing the switch using the optional, separately purchased Telco and EIA Shelf
Bracket Kit, see the “Cisco MDS 9000 Family Telco and EIA Shelf Bracket” section on page A-4.
Note The optional Telco and EIA Shelf Bracket Kit is not provided with the switch. To order the kit, contact
your switch provider.
Installation Guidelines
Follow these guidelines when installing the Cisco MDS 9216 Switch:
•Plan your site configuration and prepare the site before installing the chassis. Appendix E, “Site
Planning and Maintenance Records,” lists the recommended site planning tasks.
•Record the information listed in Appendix E, “Site Planning and Maintenance Records,” as you
install and configure the switch.
•Ensure there is adequate space around the switch to allow for servicing the switch and for adequate
airflow (Appendix C, “Technical Specifications,” lists airflow requirements).
•Ensure the air-conditioning meets the heat dissipation requirements listed in Appendix C,
“Technical Specifications.”
•Ensure the cabinet or rack meets the requirements listed in Appendix A, “Cabinet and Rack
Installation.”
Note Jumper power cords are available for use in a cabinet. See the “Jumper Power Cord” section on
page C-8.
•Ensure the chassis is adequately grounded. If the switch is not mounted in a grounded rack, we
recommend connecting both the system ground on the chassis and the power supply ground to an
earth ground.
•Ensure the site power meets the power requirements listed in Appendix C, “Technical
Specifications.” If available, you can use an uninterruptible power supply (UPS) to protect against
power failures.
Caution Avoid UPS types that use ferroresonant technology. These UPS types can become unstable
with systems like the Cisco MDS 9000 Family, which can have substantial current draw
fluctuations because of fluctuating data traffic patterns.

Chapter 2 Installing the Cisco MDS 9216 Switch
Pre-Installation
•Ensure that circuits are sized according to local and national codes. For North America, the 845-W
power supply requires a 15-A or 20-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.
Caution To prevent loss of input power, ensure the total maximum loads on the circuits supplying power to the
switch are within the current ratings for the wiring and breakers.
•Use the following screw torques when installing the switch:
– Captive screws: 4 in-lb
– M3 screws: 4 in-lb
– M4 screws: 12 in-lb
– 10-32 screws: 20 in-lb
– 12-24 screws: 30 in-lb
Required Equipment
Gather the following items before beginning the installation:
•Number 1 and number 2 Phillips screwdrivers with torque capability
•3/16-in. flat-blade screwdriver
•Tape measure and level
•ESD wrist strap or other grounding device
•Antistatic mat or antistatic foam
The following additional items (not found in the accessory kit) are required to ground the chassis:
•Grounding cable (6 AWG recommended), sized according to local and national installation
requirements; the required length depends on the proximity of the Cisco MDS 9216 Switch to proper
grounding facilities
•Crimping tool large enough to accommodate girth of lug
•Wire-stripping tool
Unpacking and Inspecting the Switch
Caution When handling switch components, wear an ESD strap and handle modules by the carrier edges only.
An ESD socket is provided on the chassis. For the ESD socket to be effective, the chassis must be
grounded through the power cable, the chassis ground, or the metal-to-metal contact with a grounded
rack.
Tip Keep the shipping container in case the chassis requires shipping in the future.

Figure 2-6 Cisco MDS 9216 Switch Chassis Installed in the Rack
Installing the Switch in a Cabinet with Insufficient Front
Clearance
This section describes how to use the rack-mount kit provided with the switch to install the Cisco MDS
9216 Switch into a cabinet with insufficient front-facing clearance. The Cisco MDS 9216 Switch is
installed rear-facing to provide adequate clearance for the fiber optic cables. This cabinet meets the
requirements described in Appendix A, “Cabinet and Rack Installation,” except the cabinet has less than
three inches of clearance between the inside of the front door or bezel panel and the front cabinet
mounting rails. This rear-facing installation is necessary to ensure that the minimum bend radius for the
fiber optic cables is maintained. In these cabinets, the Cisco MDS 9216 Switch is mounted backwards,
with the fiber optic cables facing toward the rear of the cabinet and the power supplies facing the front
of the cabinet.
Caution If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized.
