Install the Switch in NEBS-Compliant Mode

NEBS-Compliant Air Filter

A Network Equipment-Building System (NEBS) compliant installation allows filtered, front-to-rear airflow. To mount the chassis in a NEBS-compliant mode with the air filter, use a 23-inch rack mount. Filter brackets that are mounted on the side of the chassis hold the air filter.

A 23-inch rack mount is used for mounting the switch in a standard 23 inch (58.4 cm) equipment rack with two unobstructed outer posts. This kit is not suitable for racks with obstructions (such as a power strip) that could impair access to the field-replaceable units (FRUs) of the switch.

Rack-Mounting the Chassis in NEBS-Compliant Mode

Before you begin

  • Read Safety Warnings carefully before starting with any installation procedure to make sure you understand the hazards and precautions.

  • Place the chassis on the floor or on a sturdy table as close as possible to the rack. Leave enough clearance to allow you to move around the chassis.

  • Open the rack-mount kit (C9606-FB-23-KIT=) and verify that all parts are included.


Note

Some equipment racks provide a power strip along the length of one of the rear posts. If your rack has this feature, consider the position of the strip when planning fastener points. Before installing the brackets on the chassis, determine whether to install the chassis from the front or the rear of the rack.

Procedure

Step 1

Remove and discard the mounting ears and the ten mounting screws of the chassis. Do not reuse them during any part of the installation process.

Figure 23. NEBS-Compliant Air Filter


Note

 

We recommend that you change the air filter every 3 months. However, examine the air filter once a month (or more often in dusty environments) and replace it if it appears to be excessively dirty or damaged. To comply with Telecordia GR-63-Core standard air filter requirements for NEBS deployments, the air filter must be replaced, not cleaned.

Step 8

Install the top and base covers as shown in the illustrations:

Establishing System Ground

To attach the grounding lug and cable to the grounding pad, perform these steps:

Before you begin


Warning

Use copper conductors only. Statement 1025

Warning

When stranded wiring is required, use approved wiring terminations, such as closed-loop or spade-type with upturned lugs. These terminations should be the appropriate size for the wires and should clamp both the insulation and conductor. Statement 1002

Warning

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

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

  • Grounding lug—A two-hole grounding lug, which supports up to 6 AWG size. Supplied as part of the standard accessory kit.

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

  • Grounding wire—The grounding wire should be sized according to local and national installation requirements. Depending on the power supply and system, a 12 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.

Procedure

Step 1

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

Step 2

Insert the stripped end of the grounding wire into the open end of the grounding lug.

Step 3

Crimp the grounding wire in the barrel of the grounding lug. Verify that the ground wire is securely attached to the ground lug.

Step 4

Secure the grounding lug to the system ground connector with two M4 screws. Ensure that the grounding lug and the grounding wire do not interfere with other switch hardware or rack equipment.

Figure 26. System Ground Connected


Step 5

Prepare the other end of the grounding wire, and connect it to an appropriate grounding point in your site to ensure adequate earth ground for the switch.

Attaching an ESD Strap

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

Procedure

Step 1

Attach the ESD wrist strap to bare skin as follows:

  1. 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 such that it touches your bare skin well.

  2. 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. 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 either the spring clip or the alligator clip to the ground lug screw as follows:

  1. 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.

  2. 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.

When handling modules, follow these guidelines:

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

  • Place a removed component boardside 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).

Verifying the Switch Chassis Installation

To verify the switch chassis installation, perform these steps:

Procedure

Step 1

Verify that the ejector levers of each module are fully closed (parallel to the faceplate) to ensure that the supervisor and all the line cards are fully seated in the backplane connectors.

Step 2

Verify that all empty module slots and power supply bays have blanks installed properly. The blanks optimize the air flow through the chassis and contain EMI.

Warning

 

Statement 1029—Blank Faceplates and Cover Panels

Blank faceplates and cover panels serve three important functions: they reduce the risk of electric shock and fire, 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.

Step 3

Turn on the power supply switches to power up the system. During the power-up sequence, the system performs a series of bootup diagnostic tests.

Note

 

The switch is designed to boot up in less than 30 minutes, provided that the neighboring devices are in fully operational state.

What to do next

Additional system diagnostic tests are also available. These tests allow you to perform a complete sanity check on the system prior to inserting the system into your network and to monitor the health of the system while the system is running.


Tip
When prestaging systems in a nonproduction environment, we recommend that you run all the diagnostic tests, including the disruptive tests, to prescreen the systems for failures, if any.
