Note The telco and EIA Shelf Bracket Kit is optional and is not provided with the switch. To order the kit, contact your switch provider.


Installation Guidelines

Follow these guidelines when installing the Cisco MDS 9100 Series:

Plan your site configuration and prepare the site before installing the switch. The recommended site planning tasks are listed in Appendix D, "Site Planning and Maintenance Records."

Ensure there is adequate space around the switch to allow for servicing the switch and for adequate airflow (airflow requirements are listed in Appendix B, "Technical Specifications").

Ensure the air-conditioning meets the heat dissipation requirements listed in Appendix B, "Technical Specifications."

Ensure the cabinet or rack meets the requirements listed in Appendix A, "Cabinet and Rack Installation."


Note If the front cabinet mounting rails are not offset from the front door or bezel panel by a minimum of 3 in. (7.6 cm), and a minimum of 5 in. (12.7 cm) if cable management brackets are installed on the front of the chassis, the chassis should be mounted rear-facing to ensure the minimum bend radius for fiber-optic cables. See the"Installing the Switch in a Cabinet with Insufficient Front Clearance" section.



Note Jumper power cords are available for use in a cabinet. For more information, see the "Jumper Power Cord" section on page C-5.


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 B, "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 such as 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 300-W power supplies require a 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 current ratings for wiring and breakers.

As you install and configure the switch, record the information listed in the "Site Planning and Maintenance Records" section on page D-1.

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 tools before beginning the installation:

Number 1 Phillips screwdriver 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 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 2-19 Location of Switch Ground on the Cisco MDS 9100 Series


Warning When installing or replacing the unit, the ground connection must always be made first and disconnected last. Statement 1046



Caution We recommend grounding the chassis, even if the rack is already grounded.


Note If the rack is less than 25-in. (635 mm) deep, the slider rails will cover the grounding hole. Therefore, the rack must either be grounded or at least 25-in. (635 mm) deep.



Caution All power supplies must be grounded. The receptacles of the AC power cables used to provide power to the chassis must be the grounding type, and the grounding conductors should connect to protective earth ground at the service equipment.


Note The grounding lug must be NRTL listed and compatible with copper conductors. Only copper conductors (wires) must be used and the copper conductor must comply with National Electrical Code (NEC) for ampacity.



Note Customers who require compliance to GR-1089-CORE bonding and grounding requirements, must use the ground conductor.


To attach the grounding lug and cable to the chassis, follow these steps:


Step 1 Use a wire-stripping tool to remove approximately 0.75 in. (19 mm) of the covering from the end of the grounding cable.

Step 2 Insert the stripped end of 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.


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, see the Cisco MDS 9000 Family CLI Configuration Guide. For instructions on connecting to this port, see the "Connecting the Console Port" section on page 3-1.


To power up the switch and verify hardware operation, follow these steps:


Step 1 Verify that both power supplies and fan modules are installed and tighten any loose captive screws.

Step 2 Verify that the power switches on both power supplies are off. Then plug the power cables into the power supplies and arrange the cables so that they cannot be accidentally 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 9100 Series Switch switch to your outlet receptacle. See the "Jumper Power Cord" section on page C-5.


Step 3 Connect the other end of the power cables to an AC power source.

Step 4 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 (provided in the "Power Specifications" section on page B-2).

Step 5 Flip the power switches on the power supplies to the on (|) position. The switch boots automatically.

Step 6 Listen for the fans; they should begin operating as soon as 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 7 Verify that the LED behavior is as follows when the switch has finished booting:

Fan status LED is green.

Each power supply LED is green.

The Switch status LED is green. If this LED is orange or red, then one or more environmental monitors is reporting a problem.

The Ethernet port Link LEDs should not be on unless the cable is connected.


Note The LEDs for the Fibre Channel ports remain orange 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 other than the Fibre Channel port LEDs are orange or red after the initial boot processes are complete, see the Cisco MDS 9000 Family Troubleshooting Guide.

Step 8 Try removing and reinstalling a component that is not operating properly. If it still does not operate correctly, contact your customer service representative for a replacement.


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.shtm


Step 9 Verify that the system software has booted and the switch has initialized without error messages. If any problems occur, see the Cisco MDS 9000 Family Troubleshooting Guide or the Cisco MDS 9000 Family System Messages Guide. If you cannot resolve an issue, contact your customer service representative.

Step 10 Complete the worksheets provided in Appendix D, "Site Planning and Maintenance Records" for future reference.


Note A setup utility automatically launches the first time you access the switch and guides you through the basic configuration. For instructions about how to configure the switch and check module connectivity, see the Cisco MDS 9000 Family CLI Configuration Guide.

The Cisco MDS 9140 Switch and the Cisco MDS 9120 Switch also have two field-replaceable fan modules. The Cisco MDS 9134 Switch has two hot-swappable power supplies and two hot-swappable fan modules. The Cisco MDS 9124 Switch is shipped with one field-replaceable power supply and three fixed fans.

This section provides the following information:

Removing and Installing Power Supplies

Removing and Installing Fan Modules


Warning Hazardous voltage or energy is present on the backplane when the system is operating. Use caution when servicing. Statement 1034



Caution During this procedure, wear grounding wrist straps to avoid ESD damage to the switch.


Note The Cisco MDS 9100 Series is only supported for operation with both power supplies and both fan modules installed, with all fans working.


With two power supplies installed, if one power supply fails, the system can continue to function normally on a single healthy power supply. However, the failed power supply should be replaced as soon as possible to provide redundancy.

The fan modules are required to ensure proper cooling of the switches. SeeFigure 2-20, Figure 2-21, and Figure 2-22.

Figure 2-20 Rear View of the Cisco MDS9134 Switch

Figure 2-21 Rear View of the Cisco MDS 9124 Switch

For the Cisco MDS 9140 Switch and the Cisco MDS 9120 Switch, the fans should not be removed for prolonged periods of time during operation. If one fan module fails, a single healthy fan module can temporarily provide sufficient cooling to maintain switch operation under normal conditions, but the failed fan module should be replaced as soon as possible. See Figure 2-22.

This section provides instructions for removing and installing the power supplies for the Cisco MDS 9100 Series.


Caution Power supplies for the Cisco 9100 Series look similar but they differ slightly. Be sure to use the correct power supply designated for your Cisco 9100 Series switch. Using an incorrect power supply will not provide redundant power in the case of a power supply failure.

Removing Power Supplies

To remove a power supply, follow these steps:


Step 1 Turn the power switch to the off (0) position on the power supply you are removing.

Step 2 Disconnect the power cord from the power source.

Step 3 Loosen the captive screw.

Step 4 Grasp the power supply handle and slide the power supply out of the switch. See Figure 2-23.

Installing Power Supplies

To install the dual 300-W AC-input power supplies, follow these steps:


Step 1 Ensure that the system (earth) ground connection has been made.

Step 2 Make sure the power cord is disconnected before installing the power supply.

Step 3 Verify that the power switch is in the off (0) position on the power supply you are installing.

Step 4 Slide the power supply into the power supply bay. Make sure that the power supply is fully seated in the bay.

Step 5 Tighten the power supply captive screw.

Step 6 Plug the power cord into the power supply.

Step 7 Connect the other end of the power cord to an AC-input power source.


Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco MDS 9100 Series Switch to your outlet receptacle. See the "Jumper Power Cord" section on page C-5.


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 (P/S) LED in the front panel is green.

If the LED is not green, see the Cisco MDS 9000 Family Troubleshooting Guide.


Removing and Installing Fan Modules

This section provides instructions for removing and installing the fan modules for the Cisco MDS 9140 Switch and the Cisco MDS 9120 Switch. The Cisco MDS 9124 Switch does not have field-replaceable fan modules.

Removing a Fan Module on the Cisco MDS 9140 Switch, the Cisco MDS 9120 Switch, and the Cisco MDS 9134 Switch

The fan module is designed to be removed and replaced while the system is operating without presenting an electrical hazard or damaging the system.


Caution The Cisco MDS 9000 Family has 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 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.


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 the existing fan module, follow these steps:


Step 1 Locate the fan module in the back of the switch.

Step 2 Slide the seating tabs toward the center of the fan module.

Step 3 Grasp the fan module handle and pull it outward.

Step 4 Pull the fan module out of the switch and put it in a safe place.


Installing a Fan Module

To install a new fan module, follow these steps:


Step 1 Position the fan module with the LED oriented away from the back of the switch. Figure 2-24 shows the fan module for the Cisco MDS 9120 Switch and the Cisco MDS 9140 Switch. Figure 2-25 shows the fan module for the Cisco MDS 9134 Switch.

Step 2 Slide the fan module into the switch until it clicks into place.

Verifying the Fan Module

To verify that the new fan module is installed correctly, follow these steps:


Step 1 Listen for the fans; you should immediately hear them operating. If you do not hear them, ensure that the fan module is inserted completely in the switch and the faceplate is flush with the switch back panel.

Step 2 Verify that the Fan module LED is green. If the LED is orange then one fan has failed in this fan module; if the LED is red, then both fans have failed in this fan module.

Step 3 Contact your customer service representative for assistance if, after several attempts, the fans do not operate or you experience trouble with the installation.


Note Verify that the transceiver and cable type both have LC connectors and are the required type for longwave or shortwave transmission and the required distances. The transceiver label generally lists the model and wavelength.
