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.

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 9200 Series:

Plan your site configuration and prepare the site before installing the chassis. Appendix D, "Site Planning and Maintenance Records," lists the recommended site planning tasks.

Record the information listed in Appendix D, "Site Planning and Maintenance Records," as you install and configure the switch.

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

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

Ensure that 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-9.


Ensure that the chassis is adequately grounded. If the switch is not mounted in a grounded rack, Cisco recommends connecting both the system ground on the chassis and the power supply ground to an earth ground.

Ensure that 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 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

Before beginning the installation, ensure that the following items are ready:

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 9200 Series 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.

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 9200 Series into a cabinet with insufficient front-facing clearance. The Cisco MDS 9200 Series 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 9200 Series 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.

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 2-2 lists some general grounding practice guidelines.

Table 2-2 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. Best 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

Best grounding practices must be closely followed.

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

Medium to high

Best 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

Best 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

Best 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

Best 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 to protect the board from ESD, always use an ESD grounding strap when handling modules.

Follow these guidelines for preventing ESD damage:

Always use 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 9200 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. See "Establishing the System Ground" section for installation instructions and location of the chassis system ground pads.


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:

c. 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.

d. 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 2-16.):

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.

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, periodically check the resistance value of the antistatic strap. 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 9200 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 AC-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.

You do not need to power down the chassis because the MDS 9200 series chassis are equipped with AC-input power supplies.

Required Tools and Equipment

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

Grounding lug—A two holes 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.

Grounding the Chassis

The chassis has a grounding pad with two threaded M4 holes for attaching a grounding lug. Figure 2-17 shows the system ground location on the Cisco MDS 9200 Series.


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



Caution Cisco recommends grounding the chassis, even if the rack is already grounded.


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.

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



Caution Grounding the chassis is required if you are using DC power supplies, 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. The ground lug must be NRTL listed. In addition the copper conductor (wires) must be used and the copper conductor must comply with NEC code for ampacity.

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 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. During this procedure, wear grounding wrist straps to avoid ESD damage to the switch. 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 CLI Configuration Guide or the Cisco MDS 9000 Family Fabric Manager Configuration Guide. For instructions on connecting to the console port, see the "Connecting to the Console Port" section on page 3-2.



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


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 9200 Series to your outlet receptacle. See the "Jumper Power Cord" section on page C-9.


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 on page B-3).

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. 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.

The Link LEDs for the Ethernet port 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.


Step 9 Try removing and reinstalling a component that is not operating correctly. If it still does not operate correctly, contact your customer service representative for a replacement.

This section includes the following topics:

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 percent 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 9200 Series supports dual 845-W AC power supplies that monitor output voltage and provide status to the supervisor module.

This section includes the following topics:

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

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.


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 includes the following topics:

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 2-23 shows a fan module partially installed in the Cisco MDS 9200 Series.

Figure 2-23 Fan Module

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 2-23).

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 occurs, contact your customer service representative for a replacement part.
