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.
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. "Site Planning and Maintenance Records," lists the recommended site planning tasks.
•Record the information listed in "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 ("Technical Specifications," lists airflow requirements).
•Ensure the air-conditioning meets the heat dissipation requirements listed in "Technical Specifications."
•Ensure the cabinet or rack meets the requirements listed in "Cabinet and Rack Installation."
Note Jumper power cords are available for use in a cabinet. See the "Jumper Power Cord" section.
•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 "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.
•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.
Note If you purchased Cisco support through a Cisco reseller, contact the reseller directly. If you purchased support directly from Cisco, contact Cisco Technical Support at this URL: http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml
Note The switch is thoroughly inspected before shipment. If any damage occurred during transportation or any items are missing, contact your customer representative immediately.
To inspect the shipment, follow these steps:
Step 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:
•Print documentation and CD-ROMs
•Grounding lug kit

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 "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.
The rack-mount kit provided with the switch contains the items listed in Table 2-1. If you do not find all of the parts listed in Table 2-1, you may have an older version of the rack-mount kit, which only included the front rack-mount brackets. If this is the case, you can either install the switch in the rack with just the front rack-mount brackets, or contact your customer service representative for a current version of the rack-mount kit.

Step 2 Insert the stripped end of the grounding cable into the open end of the grounding lug.
Step 3 Use the crimping tool to secure the grounding cable in the grounding lug.
Step 4 Remove the adhesive label from the grounding pad on the chassis.
Step 5 Place the grounding lug against the grounding pad so that there is solid metal-to-metal contact, and insert the two M4 screws with washers through the holes in the grounding lug and into the grounding pad.
Step 6 Ensure that the lug and cable do not interfere with other equipment.
Step 7 Prepare the other end of the grounding cable and connect it to an appropriate grounding point in your site to ensure adequate earth ground.
Starting Up the Switch
This section provides instructions for powering up the switch and verifying component installation.
Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034
Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029
Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the switch.
Note Do not connect the MGMT 10/100 Ethernet port to the LAN until the initial switch configuration has been performed. For instructions on configuring the switch, refer to http://www.cisco.com/univercd/cc/td/doc/product/sn5000/mds9000/index.htm for the latest Cisco MDS 9000 Family configuration guides. For instructions on connecting to the console port, see the "Connecting to the Console Port" section.
To power up the switch and verify hardware operation, follow these steps:
Step 1 Verify that empty module slots have filler panels installed, the faceplates of all modules are flush with the front of the chassis, the ejector levers are fully closed and approximately parallel to the front of the module, and the captive screws of the power supplies, fan module, and all supervisor, switching, or services modules are tight.
Step 2 Verify that both power supplies and the fan module are installed.
Step 3 Verify that the power switches on both power supplies are off, and then plug the power cables into the power supplies and tighten the screws on the power cable retainers to ensure the cables cannot be pulled out.
Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco MDS 9216 Switch to your outlet receptacle. See the "Jumper Power Cord" section.
Step 4 Connect the other end of the power cables to an AC power source.
Step 5 Ensure that the switch is adequately grounded as described in the "Installing the Switch in a Cabinet with Insufficient Front Clearance" section, and that the power cables are connected to outlets that have the required AC power voltages (see the "Weight of Modules" section).
Step 6 Flip the power switches on the power supplies to the on (|) position. The switch boots automatically.
Step 7 Listen for the fans; they should begin operating when the switch is powered on.
Caution Do not operate the switch without a functioning fan module except for during the brief fan module replacement procedure. The Cisco MDS 9000 Family switches can operate for only a few minutes without any functioning fan modules before they begin to overheat.
Step 8 After the switch boots, verify that the LED behavior is as follows:
•Fan module: Status LED is green
•Power supplies:
–Input Ok LED is green.
–Fan Ok LED is green.
–Output Fail LED is off.
•Supervisor, switching, or services modules:
–During initialization, the status LED on the module flashes orange once, remains orange during diagnostic boot tests, then turns green when the module is operational (online). If the system software is unable to start up, this LED remains orange or turns red.
–After initialization, the status LED is green, indicating that all chassis environmental monitors are reporting that the system is operational. If this LED is orange or red, then one or more environmental monitor is reporting a problem.
•Ethernet port Link LEDs should not be on unless the cable is connected.
Note The link LEDs for the Fibre Channel ports remain yellow until the ports are enabled, and the LED for the MGMT 10/100 Ethernet port remains off until the port is connected.
If any LEDs are orange (except on the CSM) or red after the initial boot processes are complete, see "Troubleshooting."
Step 9 Try removing and re-installing a component that is not operating correctly. If it still does not operate correctly, contact your customer service representative for a replacement.
Note If you purchased this product through a Cisco reseller, contact the reseller directly for technical support. If you purchased this product directly from Cisco, contact Cisco Technical Support at this URL: http://www.cisco.com/warp/public/687/Directory/DirTAC.shtml.
Step 10 Verify that the system software has booted and the switch has initialized without error messages. If any problems occur, refer to http://www.cisco.com/univercd/cc/td/doc/product/sn5000/mds9000/index.htm for the latest Cisco MDS 9000 Family Troubleshooting Guide or the Cisco MDS 9000 Family System Messages Guide.

Step 2 If a filler panel is installed, remove the two Phillips pan-head screws from the filler panel and remove the panel. To remove a currently installed module, see the "Removing and Installing Switching and Services Modules" section.
Step 3 Open fully both ejector levers on the new or replacement module (see Figure 2-17).
Step 4 Position the module in the chassis as follows:
a. Position the module in the slot, aligning the sides of the module carrier with the slot guides on each side of the slot.
b. Slide the module carefully into the slot until the EMI gasket along the top edge of the module makes contact with the supervisor module above it and both ejector levers have closed to approximately 45 degrees with respect to the module faceplate (see Figure 2-18).
c. Grasp the two ejector levers using the thumb and forefinger of each hand and press down to create a small 0.040-in. (1 mm) gap between the module's EMI gasket and the module above it (see Figure 2-19).
Figure 2-19 Closing the Ejector Levers
Caution Do not press down too forcefully on the levers because they can bend.
d. Press down and simultaneously close the left and right ejector levers to fully seat the module in the backplane connector. The ejector levers are fully closed when they are flush with the module faceplate.
Note Ensure that the ejector levers are fully closed before tightening the captive screws. Failure to fully seat the module in the backplane connector can result in error messages.
e. Tighten the two captive screws on the module.
Verifying Installation of a Switching or Services Module
To verify the module installation in slot 2, follow these steps:
Step 1 Verify that the ejector levers of the module are fully closed (parallel to the faceplate) to ensure that the module is fully seated in the backplane connectors.
Step 2 Check the captive screws of the module, the power supply, and the fan module, and tighten any loose captive screws.
Step 3 Verify that a filler panel is installed and that the screws holding the panel in place are tightened if the slot is to remain empty.
Step 4 Turn on the power supply switches to power up the system and check the LEDs on the module.
Note For information about how to check connectivity of the module, refer to http://www.cisco.com/univercd/cc/td/doc/product/sn5000/mds9000/index.htm for the latest Cisco MDS 9000 Family configuration guides.
Maintaining a Caching Services Module
Caution Maintenance should only be performed by qualified service personnel.
Note A minimum of two CSMs in each fabric are required for redundancy and data backup.
This section provides the following information:
•Maintaining the Batteries on the Caching Services Module
•Maintaining the Disk Drives on the Caching Services Module
Maintaining the Batteries on the Caching Services Module
The CSM batteries last approximately three years. The following message displays in the system log when a battery fails:
Dec 5 17:14:36 sw-90.21 %SVC_BATTERY-SLOT8-4-BATTERY_CAPACITY_LOW:
Battery capacity is below the required threshold.
A message also appears in the output of the show interface command.
If you see this message, contact your support provider for assistance. If a battery fails, the CSM must be replaced.
Caution The CSM batteries are shipped fully charged and should be handled accordingly.
Warning Do not touch or bridge the metal contacts on the battery. Unintentional discharge of the batteries can cause serious burns. Statement 341
Warning Ultimate disposal of this product should be handled according to all national laws and regulations. Statement 1040
The batteries are automatically charged on a periodic basis with an SMBus compliant Level III smart charger located on the CSM. The smart charger measures the charge and recharges the battery to full if it is less than 90% of capacity.
The batteries are also automatically reconditioned on a periodic basis, one battery at a time. During reconditioning all power is drained from the battery and the battery is completely recharged, requiring approximately six hours. The Battery Status LED flashes green during the reconditioning.
Maintaining the Disk Drives on the Caching Services Module
A message displays in the system log when a disk drive requires replacement. If you see this message, contact your support provider for assistance.
If a disk drive fails, the CSM must be replaced. The other CSM(s) in the fabric contain the same data, and they can continue to provide caching services during the replacement period.
Removing and Installing Power Supplies
The Cisco MDS 9216 Switch supports dual 845-W AC power supplies that monitor output voltage and provide status to the supervisor module.
This section provides the following information:
•Removing a Power Supply
•Installing a Power Supply
A flat-blade or Phillips screwdriver is required to perform these procedures.
Warning Voltage is present on the backplane when the system is operating. To reduce risk of an electric shock, keep hands and fingers out of the power supply bays and backplane areas. Statement 166
Warning Power supply captive installation screws must be tight to ensure protective grounding continuity. Statement 289
Note You can replace a faulty power supply while the system is operating provided the other power supply is functioning.
Removing a Power Supply
To remove a power supply, follow these steps:
Step 1 Turn the power switch to the off (0) position.
Step 2 Loosen the screw on the power cable retainer and disconnect the power cable from the power supply being removed.
Step 3 Loosen the captive screw on the power supply.
Step 4 Grasp the power supply handle with one hand and slide it out of the chassis.
Step 5 Install a blank filler panel if the power supply bay is to remain empty.
Installing a Power Supply
To install a power supply, follow these steps:
Step 1 Ensure that the system (earth) ground connection has been made. For ground connection instructions, see the "Installing the Switch in a Cabinet with Insufficient Front Clearance" section.
Step 2 If the power supply bay has a filler panel, loosen the screws holding the panel and remove the panel.
Step 3 Verify that the power switch is in the off (0) position on the power supply you are installing. See Figure 2-20 for the location of the power switch.

Step 5 Tighten the power supply captive screws.
Step 6 Plug the power cable into the power supply, and tighten the screw on the power cable retainer to ensure the cable cannot be pulled out.
Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco MDS 9216 Switch to your outlet receptacle. See the "Jumper Power Cord" section
Step 7 Connect the other end of the power cable to an AC power source.
Caution In a system with dual power supplies, connect each power supply to a separate power source. In case of a power source failure, the second source will most likely still be available.
Step 8 Turn the power switch to the on (|) position on the power supply.
Step 9 Verify power supply operation by checking that the power supply LEDs are in the following states:
•Input Ok LED is green.
•Fan Ok LED is green.
•Output Fail LED is off.
If the LEDs indicate a power problem, see the "Troubleshooting the Power Supplies" section.
Removing and Installing the Fan Module
The fan module is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system, provided the replacement is performed promptly.
This section provides the following information:
•Removing a Fan Module
•Installing a Fan Module
You will need a flat-blade or number 2 Phillips screwdriver to perform these procedures.
Caution The Cisco MDS 9000 Family switches have internal temperature sensors that are capable of shutting down the system if the temperature at different points within the chassis exceed certain safety thresholds. To be effective, the temperature sensors require the presence of airflow; therefore, in the event a fan module is removed from the chassis, the Cisco MDS 9000 Family switches will be shut down after five minutes to prevent potentially undetectable overheating. However, the switches will shut down sooner if the higher-level temperature threshold is exceeded.
Figure 2-22 shows a fan module partially installed in the Cisco MDS 9216 Switch.

Removing a Fan Module
Warning When removing the fan tray, keep your hands and fingers away from the spinning fan blades. Let the fan blades completely stop before you remove the fan tray. Statement 258
To remove a fan module, follow these steps:
Step 1 Loosen the two captive screws on the fan module by turning them counterclockwise, using a flat-blade or number 2 Phillips screwdriver if required.
Step 2 Grasp the fan module with both hands and pull it outward; rock it gently, if necessary, to unseat the power connector from the backplane.
Step 3 Pull the fan module clear of the chassis.
Caution If the switch is powered on, you must hot-swap another fan module into this switch within five minutes.
Installing a Fan Module
To install a fan module, follow these steps:
Step 1 Hold the fan module with the Fan Status LED at the top (see Figure 2-22).
Step 2 Place the fan module into the front chassis cavity so it rests on the chassis, lift the fan module up slightly to align the top and bottom chassis guides, then push the fan module into the chassis until it seats in the backplane and the captive screws make contact with the chassis, and tighten the captive screws.
Step 3 Listen for the fans if the switch is powered on. You should immediately hear them operating. If you do not hear them, ensure that the fan module is inserted completely in the chassis and the faceplate is flush with the outside surface of the chassis.
Step 4 Verify that the Fan Status LED is green. If the LED is not green, one or more fans are faulty. If this happens, contact your customer service representative for a replacement part.
