Installation Guidelines

Follow these guidelines when installing the Cisco MDS 9500 Series:

Plan your site configuration and prepare the site before installing the chassis. Cisco recommends that you use the site planning tasks listed in "Site Planning and Maintenance Records."

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

Ensure that the air-conditioning meets the heat dissipation requirements listed in "Technical Specifications."

Ensure that the cabinet or rack meets the requirements listed in "Cabinet and Rack Installation."


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


Ensure that the chassis is adequately grounded. Grounding the chassis is recommended in all cases, and is mandatory for Cisco MDS 9506 Directors that have a DC power supply installed. If the switch is not mounted in a grounded rack or cabinet, Cisco recommends connecting the system ground on the chassis and the power supply ground to an earth ground, regardless of whether the power supplies are AC or DC.

Ensure that the site power meets the power requirements listed in "Technical Specifications." 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 1900-W AC power supplies require a 20-A circuit.

The 1900-W DC power supplies require a 70-A circuit.

The 2500-W AC power supplies require a 20-A circuit.

The 2500-W DC power supplies require a 100-A circuit.

The 4000-W AC power supplies require a 30-A circuit.

The 6000-W AC power supplies require two 220 V inputs at 20-A circuit.

If you are using 200/240 VAC power sources in North America, the circuits must be protected by two-pole circuit breakers.


Caution To prevent loss of input power, ensure that the total maximum loads on the circuits supplying power are within the current ratings of the wiring and breakers.

Record your installation and configuration information as you work. See "Site Planning and Maintenance Records."

Use the following screw torques when installing the switch:

Captive screws: 4 in-lb

M3 screws: 4 in-lb

M4 screws: 12 in-lb

M6 screws: 20 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-inch flat-blade screwdriver.

Tape measure and level.

ESD wrist strap or other grounding device.

Antistatic mat or antistatic foam.

In addition to the grounding items provided in the accessory kit, you need the following items:

Grounding cable (6 AWG recommended), sized according to local and national installation requirements; the required length depends on the proximity of the Cisco MDS 9500 to proper grounding facilities.

Crimping tool large enough to accommodate girth of lug.

Wire-stripping tool.

For DC power supplies in a Cisco MDS 9506 Director, you need two 10-32 ring lugs for each DC power supply.

For the Cisco MDS 9513 Director, you need a mechanical lift to handle the weight of the chassis.

Unpacking and Inspecting the Switch


Warning Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands. To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis and components, never attempt to lift the chassis with the handles on the power supplies or on the interface processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the weight of the chassis. Statement 5

Caution Use a mechanical lift to lift the MDS 9513 chassis. The Cisco MDS 9513 Director can weigh up to 375 lb (170 kg) when fully loaded, depending on what modules populate the chassis.


Caution Cisco recommends that a third person assist whenever the chassis is being moved or lifted. The Cisco MDS 9509 Director weighs approximately 170 lb (77 kg) when fully loaded, and the Cisco MDS 9506 Director weighs approximately 125 lb (57 kg) when fully loaded with all modules and power supplies.


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 either through the power cable, the chassis ground, or metal-to-metal contact with a grounded rack.


Tip Keep the shipping container for use when moving or shipping the chassis in the future. The shipping carton can be flattened and stored with the pallet.



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 Systems, contact Cisco Technical Support at this URL: http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html.

Installing the Cisco MDS 9513 Director in a Rack

Installing the Cisco MDS 9509 Director in a Rack

Installing the Cisco MDS 9506 Director in a Rack


Caution If the rack is on wheels, ensure that the brakes are engaged or that the rack is otherwise stabilized.


Note You can remove the modules and other field-replaceable components to make moving and positioning the chassis easier and safer. See the "Removing, Installing, and Verifying Supervisor, Switching, and Services Modules" section for instructions specific to the component.


Installing the Cisco MDS 9513 Director in a Rack

The 6000-W AC power supplies for the Cisco MDS 9513 Director are designed to provide an output power for the modules and fans. Each power supply has two AC power connections and will provide power as follows:

One AC power connection @110 VAC = No output

Two AC power connection @110 VAC = 2900-W output

One AC power connection @ 220 VAC = 2900-W output

Two AC power connection @ 220 VAC = 6000-W output


Note Power output does not include the power used by the individual modules used in the chassis.


Installation of the Cisco MDS 9513 Director in a rack requires a mechanical lift to place the chassis in the rack. Ensure that you have access to the lift during the installation process.

Table 2-1 lists the items provided in the Cisco MDS 9513 rack-mount kit.

Installing the Cisco MDS 9509 Director in a Rack


Caution If connecting a Cisco MDS 9509 Director to a 110-VAC power system, ensure that sufficient power is provided to meet the chassis power requirements for the number of modules installed.

When connected to 220 VAC, the 2500-W AC power supplies (DS-CAC-2500W) for the Cisco MDS 9509 Director are designed to provide an output power of 2331 W to power the modules and fans. When connected to a 110 VAC power system, the power supply provides approximately 1150 W. In this case, and if the power supplies are used in redundant rather than combined mode, they might not provide adequate power, depending on the number of modules loaded in the chassis.

If a 110-VAC input is chosen, a 110-VAC power cord (CAB-7513AC=) must be ordered separately.

Table 2-2 lists the items provided in the Cisco MDS 9509 rack-mount kit.


Note The rack-mount kit for the Cisco MDS 9509 Director includes side rack-mount brackets, which are required for the duration of the installation only and can be removed once the front rack-mount brackets are securely fastened to the rack-mounting rails.



Note The Cisco MDS 9500 Shelf Bracket Kit can be purchased as an optional shelf bracket kit for the Cisco MDS 9509 Director. See "Cisco MDS 9500 Shelf Bracket" section.

To install the Cisco MDS 9506 chassis in the rack using the rack-mount kit, follow these steps:


Step 1 Place all the parts and screwdrivers near the rack for easy access while attaching the switch to the rack.


Note The front rack-mount brackets are shipped installed on the switch. If they have been uninstalled, reinstall them on the switch using the M4 x 6-mm screws.


Step 2 Position a person at each side of the chassis. Grasp the bottom of the chassis and slowly lift the chassis in unison, avoiding sudden twists or moves to prevent injury. Insert the rear of the chassis between the front mounting rails (see Figure 2-9), supporting the switch inside the rack until the next step is complete.

Step 3 If you are installing the optional cable management bracket, align the holes in the cable management bracket with the holes in the front, right rack-mount brackets and the mounting rail. Ensure that the chassis is level, and pass the screws through the cable management brackets and front rack-mount bracket and into the mounting rail.


Note Because the fan tray is on the left side of the chassis, Cisco recommends using only the right side for cable management. This allows easy removal of the fan tray if you need to replace a fan.


Step 4 Align the holes in the front rack-mount bracket with the holes in the mounting rail, and ensure that the chassis is level. Insert the 12-24 x 3/4-inch or 10-32 x 3/4-inch screws (depending on the type of holes in the mounting rails) through the holes in the front rack-mount bracket and into the holes in the mounting rails, using four screws per side.


Caution Use a minimum of four screws per side to ensure that the switch is adequately supported by the front rack-mount brackets.

System Grounding

This section describes the need for system grounding and explains how to prevent damage from electrostatic discharge.

Proper Grounding Practices

Grounding is one of the most important parts of equipment installation. Proper grounding practices ensure that the buildings and the installed equipment within them have low-impedance connections and low-voltage differentials between chassis. When you properly ground systems during installation, you reduce or prevent shock hazards, equipment damage due to transients, and data corruption. Table 2-4 lists grounding best practices.

Table 2-4 Grounding Best Practices

Environment
Electromagnetic Noise Severity Level
Grounding Recommendations

Commercial building is subjected to direct lightning strikes.

For example, some places in the United States, such as Florida, are subject to more lightning strikes than other areas.

High

All lightning protection devices must be installed in strict accordance with manufacturer recommendations. Conductors carrying lightning current should be spaced away from power and data lines in accordance with applicable recommendations and codes. Appropriate grounding practices must be closely followed.

Commercial building is located in an area where lightning storms frequently occur but is not subject to direct lightning strikes.

High

Appropriate grounding practices must be closely followed.

Commercial building contains a mix of information technology equipment and industrial equipment, such as welding.

Medium to high

Appropriate grounding practices must be closely followed.

Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment. This installation has a history of malfunction due to electromagnetic noise.

Medium

Appropriate grounding practices must be closely followed. Determine source and cause of noise if possible, and mitigate as closely as possible at the noise source or reduce coupling from the noise source to the victim equipment.

New commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.

Low

Appropriate grounding practices should be followed as closely as possible. Electromagnetic noise problems are not anticipated, but installing a best practice grounding system in a new building is often the least expensive route and the best way to plan for the future.

Existing commercial building is not subject to natural environmental noise or man-made industrial noise. This building contains a standard office environment.

Low

Appropriate grounding practices should be followed as much as possible. Electromagnetic noise problems are not anticipated, but installing a best practice grounding system is always recommended.



Note In all situations, grounding practices must comply with local National Electric Code (NEC) requirements or local laws and regulations.



Note Always ensure that all of the modules are completely installed and that the captive installation screws are fully tightened. In addition, ensure that all I/O cables and power cords are properly seated. These practices are normal installation practices and must be followed in all installations.


Preventing Electrostatic Discharge Damage

Electrostatic discharge (ESD) damage, which can occur when modules or other FRUs are improperly handled, results in intermittent or complete failures. Modules consist of printed circuit boards that are fixed in metal carriers. Electromagnetic interference (EMI) shielding and connectors are integral components of the carrier. Although the metal carrier helps protect the board from ESD. Always wear an ESD grounding strap when handling modules.

Follow these guidelines for preventing ESD damage:

Always wear an ESD wrist strap and ensure that it makes maximum contact with bare skin. ESD grounding straps are available with banana plugs, metal spring clips, or alligator clips. All MDS 9500 series chassis are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the front panel. Cisco recommends that you use a personal ESD grounding strap equipped with a banana plug.

If you choose to use the disposable ESD wrist strap supplied with most FRUs or an ESD wrist strap equipped with an alligator clip, you must attach the system ground lug to the chassis in order to provide a proper grounding point for the ESD wrist strap.


Note This system ground is also referred to as the network equipment building system (NEBS) ground.


If your chassis does not have the system ground attached, you must install the system ground lug. For installation instructions and location of the chassis system ground pads, see "Establishing the System Ground" section.


Note You do not need to attach a supplemental system ground wire to the system ground lug; the lug provides a direct path to the bare metal of the chassis.


After you install the system ground lug, follow these steps to correctly attach the ESD wrist strap:


Step 1 Attach the ESD wrist strap to bare skin as follows:

a. If you are using the ESD wrist strap supplied with the FRUs, open the wrist strap package and unwrap the ESD wrist strap. Place the black conductive loop over your wrist and tighten the strap so that it makes good contact with your bare skin.

b. If you are using an ESD wrist strap equipped with an alligator clip, open the package and remove the ESD wrist strap. Locate the end of the wrist strap that attaches to your body and secure it to your bare skin.

Step 2 Grasp the spring or alligator clip on the ESD wrist strap and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. Cisco recommends that you touch the clip to an unpainted rack rail so that any built-up static charge is then safely dissipated to the entire rack.

Step 3 Attach either the spring clip or the alligator clip to the ground lug screw as follows (see Figure 2-10):

a. If you are using the ESD wrist strap that is supplied with the FRUs, squeeze the spring clip jaws open, position the spring clip to one side of the system ground lug screw head, and slide the spring clip over the lug screw head so that the spring clip jaws close behind the lug screw head.


Note The spring clip jaws do not open wide enough to fit directly over the head of the lug screw or the lug barrel.


b. If you are using an ESD wrist strap that is equipped with an alligator clip, attach the alligator clip directly over the head of the system ground lug screw or to the system ground lug barrel.

Side view of grounding lug (clip slid behind screw)

 


c. In addition, follow these guidelines when handling modules:

Handle carriers by available handles or edges only; avoid touching the printed circuit boards or connectors.

Place a removed component board-side-up on an antistatic surface or in a static shielding container. If you plan to return the component to the factory, immediately place it in a static shielding container.

Never attempt to remove the printed circuit board from the metal carrier.



Caution For safety reasons, check the resistance value of the antistatic strap periodically. The measurement should be between 1 and 10 megohm (Mohm).

Establishing the System Ground

This section describes how to connect a system ground to the MDS 9500 series switches.


Note This system ground is also referred to as the network equipment building system (NEBS) ground.


You must use the system (NEBS) ground on both AC- and DC-powered systems if you are installing this equipment in a U.S. or European Central Office.

The system (NEBS) ground provides additional grounding for EMI shielding requirements and grounding for the low-voltage supplies (DC-DC converters) on the modules and is intended to satisfy the Telcordia Technologies NEBS requirements for supplemental bonding and grounding connections. You must observe the following system grounding guidelines for your chassis:

You must install the system (NEBS) ground connection with any other rack or system power ground connections that you make. The system ground connection is required if this equipment is installed in a U.S. or European Central Office.

You must connect both the system (NEBS) ground connection and the power supply ground connection to an earth ground. The system (NEBS) ground connection is required if this equipment is installed in a U.S. or European Central Office.

For MDS 9500 series chassis that are equipped with DC-input power supplies, you must install the system (NEBS) ground before you attach the source DC power cables to the DC PEM. If the chassis is powered up, you must power down the chassis before attaching the system (NEBS) ground. If you are installing the system (NEBS) ground on models of the MDS 9500 series chassis that are equipped with either AC-input or DC-input power supplies, you do not need to power down the chassis.


Note The system (NEBS) ground serves as the primary safety ground for the MDS 9500 series chassis that are equipped with DC-input PEMs. The DC-input power supplies for these chassis do not have a separate ground.


Required Tools and Equipment

To connect the ground system, you need the following tools and materials:

Grounding lug—A two-hole standard barrel lug. Supports up to 6 AWG wire. Supplied as part of accessory kit.

Grounding screws—Two M4 x 8mm (metric) pan-head screws. Supplied as part of the accessory kit.

Grounding wire—Not supplied as part of accessory kit. The grounding wire should be sized according to 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. Commercially available 6 AWG wire is recommended. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.

No. 1 Phillips screwdriver.

Crimping tool to crimp the grounding wire to the grounding lug.

Wire-stripping tool to remove the insulation from the grounding wire.

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 the following information:

Connecting the Power Supplies

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

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


Note The 2500-W (DS-CAC-2500W) power supplies provide power according to the input voltage. If they are in redundant rather than combined mode at 110 VAC, they may be unable to provide adequate power to all modules present in the system. See "Technical Specifications."


Connecting the Power Supplies

The Cisco MDS 9513 Director uses a 6000-W power supply. The 6000-W AC power supplies for the Cisco MDS 9513 Director are designed to provide an output power for the modules and fans. Each power supply has two AC power connections and will provide power as follows:

One AC power connection @110 VAC = No output

Two AC power connection @110 VAC = 2900-W output

One AC power connection @ 220 VAC = 2900-W output

Two AC power connection @ 220 VAC = 6000-W output


Note Power output does not include the power used by the individual modules used in the chassis.


The Cisco MDS 9509 Director and Cisco MDS 9506 Director support both AC and DC power supplies.

The Cisco MDS 9506 Director uses power entry modules (PEMs) to provide power to its power supplies, whether they are AC or DC (there is no power connector on the power supplies). The left PEM (as viewed from the front of the switch) provides power to the upper power supply in the back of the Cisco MDS 9506 Director, and the right PEM provides power to the lower power supply.

This section provides the following topics:

Powering Up the Switch and Verifying Component Installation


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

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 NX-OS Fundamentals Configuration Guide or the Cisco DCNM SAN Fundamentals Configuration Guide.


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 the faceplates of all modules are flush with the front of the chassis, and the ejector levers are fully closed and approximately parallel to the faceplate of the module.

Step 2 Verify that any empty module slots have filler panels installed.

Step 3 Verify that both power supplies and the fan module are installed.

Step 4 If any optional CompactFlash cards are installed, verify that the ejector button is popped out.

Step 5 Check the captive screws of the power supplies, fan module, and all supervisor, switching, or services modules, and tighten any loose captive screws.

Step 6 Ensure that the switch is adequately grounded as described in the "System Grounding" section, and that the power cables are connected to outlets that have the required AC or DC power voltages. See "Technical Specifications," for the required voltages.

Step 7 Power on the switch by turning the power switches on the power supplies or PEMs to the on (|) position or restoring power to the DC circuit, as required. The switch boots automatically.

Step 8 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 during the brief fan module replacement procedure. The Cisco MDS 9000 Family switches can operate for only a few minutes without a functioning fan module before they begin to overheat.

Step 9 After the switch has finished booting, 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:

The System LED on the supervisor module 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.

The Status LED on the switching or services modules flashes orange once, remains orange during diagnostic boot tests, then turns green when the module is operational (online). If the system software cannot start up, this LED remains orange or turns red.


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 remain orange or red after the initial boot processes are complete, see "Technical Specifications."

Step 10 If a component is not operating correctly, try removing and reinstalling it. If it still does not operate correctly, contact your customer service representative for a replacement.

Note Install the Cisco MDS 9500 Series chassis in the rack before installing modules. See the "Installing the Chassis in a Cabinet or Rack" section.



Note In systems with redundant supervisor modules, you can replace the faulty supervisor while the system is operating, provided that one supervisor is always operating.


Removing Supervisor Modules

To remove a Supervisor-1, Supervisor-2, or Supervisor-2A module from the chassis, follow these steps:


Step 1 Shut down the crossbar switching fabric functionality in the supervisor module of the Cisco MDS 9509 and 9506 Directors by using the out-of-service module slot command (where slot refers to the slot number for the Supervisor-1 or Supervisor-2 module where the integrated crossbar is located).

Step 2 Upload the current configuration to a server if the switch has only one supervisor module. For information about the correct command, see the Cisco MDS 9000 Family NX-OS Fundamentals Configuration Guide.

Step 3 Fail over to the standby supervisor if the switch has two supervisor modules and the supervisor you are removing is currently active. For information on how to fail over a supervisor module, see the Cisco MDS 9000 Family NX-OS Fundamentals Configuration Guide.

Step 4 Disconnect any network interface cables attached to the module.

Step 5 Loosen the two captive screws on the module being removed.

Step 6 Remove the module from the chassis as follows:

a. Place your thumbs on the left and right ejector levers and simultaneously rotate the levers outward to unseat the module from the backplane connector.

b. Grasp the front edge of the module and slide the module partially out of the slot. Place your other hand under the module to support the weight of the module. Do not touch the module circuitry.

Step 7 Place the module on an antistatic mat or antistatic foam, or immediately reinstall it in another slot.

Step 8 Install a filler panel on an empty slot to keep the chassis dust-free and to maintain proper airflow through the chassis.


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

Installing Supervisor Modules

In a Cisco MDS 9513 Director, slots 7 and 8 are reserved for the Supervisor- 2 and Supervisor 2A modules. In the Cisco MDS 9509 Director, slot 5 is reserved for the Supervisor-1, Supervisor- 2, or Supervisor- 2A module. In the Cisco MDS 9506 Director, slot 5 is reserved for the Supervisor-1 module. Slot 6 in the Cisco MDS 9509 and 9506 Directors is reserved for an additional redundant supervisor module in case the supervisor module in slot 5 fails. See Figure 1-3 and Figure 1-4 for slot locations.

Supervisor-1, Supervisor- 2,and Supervisor-2A modules cannot be used in the same switch, except for migration purposes. Both the active and standby supervisor modules must be of the same type, either Supervisor-1 or Supervisor-2 modules. For Cisco MDS 9513 Directors, both supervisor modules must be Supervisor-2 modules.


Step 1 Before installing any modules in the chassis, Cisco recommends installing the chassis in the rack. See the "Installing the Chassis in a Cabinet or Rack" section.

Step 2 Verify that there is enough clearance to accommodate any cables or interface equipment that you want to connect to the module.

Step 3 Verify that the captive screws are tightened to 8 in-lb on all modules already installed in the chassis. This ensures that the EMI gaskets are fully compressed and maximizes the opening space for the module being installed.

Step 4 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 Other Switching and Services Modules" section.

Step 5 Open both the ejector levers on the new or replacement module completely. (See Figure 2-22.)

Step 7 Position the module in the chassis as follows:

a. Position the module in the slot. Ensure that you align 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 contacts the module in the slot above it and both ejector levers close to approximately 45 degrees with respect to the front of the module. (See Figure 2-23.)

c. Grasp the two ejector levers using the thumb and forefinger of each hand, and press down to create a small 0.040-inch (1-mm) gap between the module's EMI gasket and the module above it. (See Figure 2-24.)


Caution Do not press down too forcefully on the levers because they can bend.

d. While pressing down, simultaneously close the left and right ejector levers to fully seat the supervisor module or switching module in the backplane connector. The ejector levers are fully closed when they are flush with the front of the module.


Note Ensure 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 supervisor module or switching module to 8 in-lb.

Step 8 If you replaced the standby supervisor module in a switch that has two supervisors and is running Cisco MDS SAN-OS Release 1.2(2a) or earlier, enable the automatic synchronization feature, which is disabled by default.

Step 9 If you replaced the supervisor in a switch that does not have a second supervisor or is running Cisco MDS SAN-OS Release 1.3(1) or later or NX-OS Release 4.1(1b), download the configuration from the server to the nonvolatile memory of the supervisor. For more information, see the Cisco MDS 9000 Family NX-OS Fundamentals Configuration Guide.


Verifying Installation of Supervisor, Switching, and Services Modules

To verify the module installation, follow these steps:


Step 1 Verify that the ejector levers of each module are fully closed (parallel to the front of the module) to ensure that the supervisor module and all switching or services modules are fully seated in the backplane connectors.

Step 2 Check the captive screws of each module, the power supply, and the fan module. Tighten any loose captive screws to 8 in-lb.

Step 3 Verify that any empty module slots have filler panels installed and that the screws holding the panels in place are tight.

Step 4 Turn on the power supply switches to power up the system and check the LEDs on the modules.


Note For information about how to check connectivity of modules, see the Cisco MDS 9000 Family NX-OS Fundamentals Configuration Guide.

Removing and Installing Fan Modules

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.

The Cisco MDS 9513 fan module has 15 fans with an abrupt stop-to-fan rotation safety feature after power is disconnected or the fan tray is removed from the midplane. The Cisco MDS 9506 fan module has six fans and the Cisco MDS 9509 fan module has nine fans. The removal procedures differ slightly while the installation procedures are the same for all types of fan modules.

You need a flat-blade or number 2 Phillips screwdriver to perform these procedures.


Note Because the fan modules are located on the left side of the Cisco MDS 9500 Series, Cisco recommends guiding the cables for the system out of the right side of the chassis.



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 be shut down sooner if the higher-level temperature threshold is exceeded.

Removing and Installing CompactFlash Cards

The supervisor module has one slot for an optional CompactFlash card. You can use this slot to install additional flash memory for storing and running software images and configuration files, or to serve as an I/O device.


Caution Only use CompactFlash devices that are certified for use with Cisco MDS switches and are formatted using Cisco MDS switches. Using CompactFlash devices that are uncertified or are formatted using other platforms may result in errors. For information on formatting the external CompactFlash, see the Cisco MDS 9000 Family NX-OS Fundamentals Configuration Guide or the Cisco DCNM SAN Fundamentals Configuration Guide.

You can install and remove the CompactFlash card with the switch powered on.


Caution Do not remove the CompactFlash card while the access LED light is on or the file may be corrupted.

This section describes how to install and remove a CompactFlash card. For additional information about the CompactFlash card, see the Cisco MDS 9000 Family NX-OS Fundamentals Configuration Guide or the Cisco DCNM SAN Fundamentals Configuration Guide.

Step 1 Verify that no operations are in progress by verifying that the LED is off.

Step 2 Press the ejector button until the card is free of the connector at the back.

Step 3 Remove the card from the slot and place it in an antistatic bag.


Installing a CompactFlash Card

To install a CompactFlash card, follow these steps:


Step 1 Position the CompactFlash card with the connector end of the card toward the slot. The connector end of the card is on the opposite side of the write-protection switch.

Step 2 Insert the card into the slot until the card is firmly seated in the connector at the back of the slot and the ejector button pops out toward you.


Caution The card does not insert all the way inside the slot; a portion of the card remains outside the slot. Do not attempt to force the card past this point or you could damage the connector pins.

Removing and Installing Clock Modules

The Cisco MDS 9500 Series includes one or more clock modules that are accessible from the back of the chassis. In the unlikely event of a clock module failure, Cisco recommends that the failed clock module be replaced during a maintenance window. The Cisco MDS 9513 and 9509 Directors have two field-replacable clock modules. The Cisco MDS 9506 Director has one field-replacable clock module. A separate procedure is provided for each type of director:
