Preparing for Installation

This section describes how to install the Cisco UCS 6100 and contains the following topics:

Installation Options

Installation Guidelines

Required Equipment

Unpacking and Inspecting the Cisco UCS 6100 Series Fabric Interconnect

Installation Options

You can install the Cisco UCS 6100 Series Fabric Interconnect chassis in a perforated or solid-walled EIA cabinet or an open EIA rack (the Cisco R Series Rack is an ideal choice), using the rack-mount kit shipped with the chassis (N10-SACCA= or N10-SACCB=), for instructions on installing the chassis using the rack-mount kit shipped with the chassis, see the "Installing the Cisco UCS 6120XP Chassis in a Cabinet or Rack" section.

Airflow Considerations

Airflow through the Cisco UCS 6100 Series Fabric Interconnect is from front to back. Air enters the chassis through the fan trays and power supplies mounted at the front of the chassis and exits the chassis through perforations on the rear of the chassis. To ensure proper airflow, follow these guidelines:

Maintain ambient airflow throughout the data center to ensure normal operation.

Consider the heat dissipation of all equipment when determining air conditioning requirements. When evaluating airflow requirements, take into consideration that hot air generated by equipment at the bottom of the rack can be drawn in the intake ports of the equipment above.

Be sure to allow unobstructed exhaust air flow.

Chassis Weight

When lifting the system, follow these guidelines:

Disconnect all power and external cables before lifting the system.

Have two people to lift the system. The Cisco UCS 6120XP weighs 35 pounds (15.9 kg). The Cisco UCS 6140XP weighs 50 pounds (22.7 kg)

Ensure that your footing is solid and the weight of the system is evenly distributed between your feet.

Lift the system slowly, keeping your back straight. Lift with your legs, not with your back. Bend at the knees, not at the waist.

Installation Guidelines

When installing the Cisco UCS 6100 Series Fabric Interconnect, follow these guidelines:

Prepare the site as described in the Cisco UCS Site Preparation Guide.

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

Record the information listed in Appendix C, "Site Planning and Maintenance Records," as you install and configure the fabric interconnect.

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

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


Note Jumper power cords are available for use in a cabinet. See the "Jumper Power Cord" section on page B-8.


Ensure that the chassis is adequately grounded. If the chassis 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 that the site power meets the power requirements listed in Appendix A, "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 UCS 6100 Series Fabric Interconnect, 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 power supply requires a 15-A or 20-A circuit.


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

Use the following screw torques when installing the chassis:

Captive screws: 4 in-lb (0.45 N·m)

M3 screws: 4 in-lb (0.45 N·m)

M4 screws: 12 in-lb (1.36 N·m)

10-32 screws: 20 in-lb (2.26 N·m)

12-24 screws: 30 in-lb (3.39 N·m)

Cabinet and Rack Requirements

This section provides the requirements for the following types of cabinets and racks, assuming an external ambient air temperature range of 0 to 104oF (0 to 40oC):

Standard perforated cabinets (60% or greater perforation front and back is required, the Cisco R Series rack is an ideal choice)

Standard open racks


Note If you are selecting an enclosed cabinet, we recommend one of the thermally validated types: standard perforated or solid-walled with a fan tray.



Note Do not use racks that have obstructions (such as power strips), because the obstructions could impair access to field-replaceable units (FRUs). The Cisco RP series PDUs when mounted in a Cisco R Series Rack should not obstruct FRU replacement.


General Requirements for Cabinets and Racks

The cabinet or rack must be one of the following types:

Standard 19 in. (48.3 cm) (four-post EIA cabinet or rack, with mounting rails that conform to English universal hole spacing per section 1 of ANSI/EIA-310-D-1992. See the "Requirements Specific to Perforated Cabinets" section. (The Cisco R Series Rack is an ideal choice.)

The cabinet or rack must also meet the following requirements:

The minimum vertical rack space per Cisco UCS 6120XP chassis must be one RU (rack unit), equal to 1.75 in. (4.4 cm).

The minimum vertical rack space per Cisco UCS 6140XP chassis must be two RU (rack unit), equal to 3.5 in. (8.8 cm).

The width between the rack-mounting rails must be at least 17.72 in. (45.0 cm) if the rear of the chassis is not attached to the rack. For four-post EIA racks, this is the distance between the two front rails.

For four-post EIA cabinets (perforated):

The minimum spacing for the bend radius for fiber-optic cables should have the front-mounting rails of the cabinet offset from the front door 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 distance between the outside face of the front mounting rail and the outside face of the back mounting rail should be 23.5 to 34.0 in. (59.7 to 86.4 cm) to allow for rear-bracket installation.

A minimum of 2.5 in. (6.4 cm) of clear space should exist between the side edge of the chassis and the side wall of the cabinet. No sizeable flow obstructions should be immediately in the way of chassis air intake or exhaust vents.


Note Optional jumper power cords are available for use in a cabinet. See the "Jumper Power Cord" section on page B-8.


Requirements Specific to Perforated Cabinets

A perforated cabinet is defined here as a cabinet with perforated front and rear doors and solid side walls. In addition to the requirements listed in the "General Requirements for Cabinets and Racks" section, perforated cabinets must meet the following requirements:

The front and rear doors must have at least a 60 percent open area perforation pattern, with at least 15 square inches of open area per rack unit of door height.

The roof should be perforated with at least a 20 percent open area.

The cabinet floor should be open or perforated to enhance cooling.

The Cisco RSeries racks meet or exceed all these requirements.

Requirements Specific to Standard Open Racks

In addition to the requirements listed in the "General Requirements for Cabinets and Racks" section, if mounting the chassis in an open rack (no side panels or doors), ensure that the rack meets the following requirements:

The minimum vertical rack space per chassis must be one RU (rack unit), equal to 1.75 in. (4.4 cm).

The horizontal distance between the chassis and any adjacent chassis should be 6 in. (15.2 cm), and the distance between the chassis air vents and any walls should be 2.5 in. (6.4 cm).

The Cisco RSeries racks meet or exceed all these requirements.

Cable Management Guidelines

To help with cable management, you might want to allow additional space in the rack above and below the chassis to make it easier to route as many as 56 fiber or copper cables through the rack.

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 UCS 6100 Series Fabric Interconnect to proper grounding facilities

Crimping tool large enough to accommodate girth of lug

Wire-stripping tool

Unpacking and Inspecting the Cisco UCS 6100 Series Fabric Interconnect


Caution When handling chassis 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.

Grounding the System

This section describes the need for system grounding, explains how to prevent damage from electrostatic discharge, and includes the following topics:

Proper Grounding Practices

Preventing Electrostatic Discharge Damage

Establishing the System Ground

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 2-3 lists some general grounding practice guidelines.

Table 2-3 Proper Grounding Guidelines 

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 recommendations 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 recommendations must be closely followed.

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

Medium to high

Best grounding recommendations 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

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 affected equipment. Best grounding recommendations must be closely followed.

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

Low

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

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

Low

Electromagnetic noise problems are not anticipated, but installing a grounding system is always recommended. Best grounding recommendations should be followed as much as possible.



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 devices 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.

For preventing ESD damage, follow these guidelines:

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 Cisco UCS 6100 Series Fabric Interconnect chassis are equipped with a banana plug connector (identified by the ground symbol next to the connector) somewhere on the front panel. We recommend 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 field-replaceable units 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.


Before 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. 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 and momentarily touch the clip to a bare metal spot (unpainted surface) on the rack. We recommend 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 the ESD strap to the system ground in one of the following ways:

If you are using a wrist strap that is equipped with a plug, insert the plug into an open screw hole used for the grounding lug as shown in Figure 2-7.

Figure 2-7 Plugging the ESD Wrist Strap to the Cisco UCS 6120XP System Ground

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.


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 Cisco UCS 6100 Series Fabric Interconnect.


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


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

The 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 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 NEBS ground connection and the power supply ground connection to an earth ground. The 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 Cisco UCS 6100 Series Fabric Interconnect is equipped with AC-input power supplies.

Required Tools and Equipment

To connect the system ground, 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 chassis to proper grounding facilities.

No. 1 Phillips head 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 2-10 shows how to ground the Cisco UCS 6120XP. Figure 2-11 shows how to ground the Cisco UCS 6140XP.


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.


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.

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 inches (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 the System

This section describes how to power up the system and verify component installation.


Note Do not connect the Ethernet port to the LAN until the initial system configuration has been performed. For instructions on configuring the system, see theCisco UCS Manager CLI Configuration Guide. For instructions on connecting to the console port, see the "Connecting to the Console Port" section on page 3-1.



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



Warning The plug-socket combination must be accessible at all times, because it serves as the main disconnecting device. Statement 1019


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


Step 1 Verify that empty power supply slots have filler panels installed, the faceplates of all modules are flush with the front of the chassis, and the captive screws of the power supplies, fan module, and all expansion modules are tight.

Step 2 Verify that the power supply and the fan modules are installed.


Note Depending on the outlet receptacle on your power distribution unit, you may need the optional jumper power cord to connect the Cisco UCS 6100 Series Fabric Interconnect to your outlet receptacle. See the "Jumper Power Cord" section on page B-8.


Step 3 Ensure that the chassis is adequately grounded as described in the "Grounding the System" section, and that the power cables are connected to outlets that have the required AC power voltages (see the "Power Specifications" section on page A-2).

Step 4 For a first-time installation, you will need to work with your network manager to determine the following parameters:

System name

Password for the admin account. Choose a strong password that meets the guidelines for Cisco UCS Manager passwords. This password cannot be blank.

Management port IP address and subnet mask

Default gateway IP address

DNS server IP address (optional)

Domain name for the system (optional)

Step 5 Connect a PC or laptop directly to the console port of the primary or standalone fabric interconnect. In a cluster configuration, the primary will be the fabric interconnect that powers up first. The console port on the terminal should be set to 9600 baud, 8 data bits, no parity, 1 stop bit.

Step 6 If the fabric interconnect will be running in a cluster with another fabric interconnect, you will need to connect ethernet cables between the L1 and L2 ports. Port L1 on fabric interconnect A connects to L1 on fabric interconnect B, and Port L2 on fabric interconnect A connects to L2 on fabric interconnect B. If the fabric interconnect and the UCS instance will be in standalone mode this will not be necessary.

Step 7 Connect the power cable to an AC power source. The system should power on as soon as you connect the power cable.

Step 8 Listen for the fans; they should begin operating when you plug in the power cable.

Step 9 After the system boots, verify that the LED operation is as follows:

Fan module—Status LED is green.

Power supply—Status LED is green.

After initialization, the system status LED is green, indicating that all chassis environmental monitors are reporting that the system is operational. If this LED is orange or red, one or more environmental monitor is reporting a problem.

The Link LEDs for the Ethernet connector 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 Ethernet connector port remains off until the port is connected.


Step 10 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.

Step 11 Verify that the system software has booted and that the system has initialized without error messages.

If any problems occur, see Appendix D, "Troubleshooting Hardware Components." If you cannot resolve an issue, contact your customer service representative.

Step 12 Complete the worksheets provided in Appendix C, "Site Planning and Maintenance Records," for future reference.

Step 13 Configure the primary fabric interconnect as descrubed in the Configuration guide for your software release. The procedure is in the "System Configuration" section, "Configuring the Fabric Interconnects" chapter.

Step 14 Power up, connect the terminal to the console port, and configure the secondary fabric interconnect as descrubed in the Configuration guide for your software release. The procedure is in the "System Configuration" section, "Configuring the Fabric Interconnects" chapter.


Note A setup utility launches automatically the first time you access the system and guides you through the basic configuration.

Preparing a Fabric Interconnect for Removal

Removing a standby fabric interconnect is non-disruptive to a UCS system. Removing an active fabric interconnect will cause the standby fabric interconnect to become active with minimal or no disruption.

Be aware that if you remove both the active and standby fabric interconnect from a UCS system, or the sole fabric interconnect from a standalone system, you are shutting down the entire UCS instance. Before doing this, perform the following tasks:

1. Perform a backup of your UCS Manager configuration as discussed in the "System Management" section, "Backing Up and Restoring the Configuration" chapter of the UCS Manager configuration guide for your software release.

1. Use UCS Manager to shut down the OS on all servers in the UCS instance. Graceful shutdown of a blade server is discussed in the "System Management" section, "Managing Blade Servers" chapter of the UCS Manager configuration guide for your software release. The related CLI commands are:

UCS-A# scope org 
UCS-A /org # scope service-profile service-profile-name 
UCS-A /org/service-profile # power down 

2. Disable the Smart Call Home feature, as mentioned in the "System Monitoring" section, "Configuring Call Home" chapter of the UCS Manager configuration guide for your software release. The related CLI commands are:

UCS-A# scope monitoring
UCS-A /monitoring # scope callhome 
UCS-A /monitoring/callhome # disable 

3. Decommision every attached chassis as described in the "System Management" section, "Managing the Chassis" chapter of the UCS Manager configuration guide for your software release. The related CLI command is decommission-chassis chassis-num .

4. Power down every attached chassis as decribed in the installation chapter of the Cisco UCS 5108 Server Chassis Installation Guide.

When powering down and removing clustered fabric interconnects, remove the secondary first, and then remove the primary.
