Step 1

Verify that you have received all the listed equipment:

  • Grounding lug and disposable electrostatic discharge (ESD) strap.
  • Optional equipment that you ordered, such as console cables, transceivers, or special connectors.
  • Blank covers installed for the power supply slots on the chassis.

Step 2

Verify the contents of the accessory kits.

Tools and equipment

To connect the system ground, you need these tools and materials.

  • Grounding lug: When using the double-hole lug connector provided with the system, the ground wire must be 6 AWG only. Otherwise, a supported closed-loop ring connector must be used for 8-14 AWG wire.
    • Two-hole 2 AWG lug is provided with the accessory kit. If you choose to use a different sized ground wire, you must procure your own two-hole lug that has .25 inch holes and .625 inch spacing between the holes.
  • Grounding screws: Two M4.0 x 6mm Phillips 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. For U.S. installations, AC power supply systems require a 14 AWG copper conductor. Commercially available 8-14 AWG wire is recommended. DC power supply systems with 930W power supply module require a 12 AWG wire and 1500W power supply module require a 8 AWG wire. The length of the grounding wire depends on the proximity of the switch to proper grounding facilities.
  • Crimping tool to crimp the grounding wire to the grounding lug.
  • Wire-stripping tool to remove the insulation from the grounding wire.
  • 2 M4 screws to fix a ground lug.

To rack mount the switch, you need these tools

  • 16 M4 screws to fix brackets
  • 3/16-inch flat-blade screwdriver.
  • Antistatic mat or antistatic foam.
  • ESD wrist strap or other grounding device.
  • No. 1 and number 2 Phillips screwdrivers with torque capability to rack-mount the chassis.
  • Tape measure and level.

Ground the switch

Adhere to these safety warnings before grounding the switch.

Installations that rely solely on system grounding using only an AC third-prong ground run a substantially greater risk of equipment problems and data corruption than those installations that use both the AC third-prong ground and a properly installed system ground.

The system ground provides additional grounding for EMI shielding requirements and grounding for the low voltage supplies (DC-DC converters) on the modules. You must observe the following system grounding guidelines for your chassis:

  • You must install the system ground connection with any other rack or system power ground connections that you make. The system ground connection is required if modules are installed or if this equipment is installed in a U.S. or European Central Office.
  • You must connect both the system ground connection and the power supply ground connection to an earth ground. The system ground connection is required if Foreign Exchange Station (FXS) modules are installed or if this equipment is installed in a U.S. or European Central Office.
  • When using DC-input power supplies, you must install the system ground before you attach the source DC power cables to the DC Power Entry Module (PEM). Power down the chassis before attaching the system ground.
 Note

In all situations, grounding practices must comply with Section 250 of the National Electric Code (NEC) requirements or local laws and regulations. A 6 American Wire Gauge (AWG) grounding wire is recommended from the chassis to the rack ground or directly to the common bonding network (CBN). The equipment rack should also be connected to the CBN with a 6 AWG grounding wire.

The system ground serves as the primary safety ground for chassis that are equipped with DC-input power supplies. The DC-input power supplies for these chassis do not have a separate ground.

 Warning

Statement 1024—Ground Conductor

This equipment must be grounded. To reduce the risk of electric shock, never defeat the ground conductor or operate the equipment in the absence of a suitably installed ground conductor. Contact the appropriate electrical inspection authority or an electrician if you are uncertain that suitable grounding is available.

 Warning

Statement 1046—Installing or Replacing the Unit

To reduce risk of electric shock, when installing or replacing the unit, the ground connection must always be made first and disconnected last.

If your unit has modules, secure them with the provided screws.

 Warning

Statement 1101—Connected To Grounded Outlet

In the Scandinavian countries (Denmark, Finland, Iceland, Norway, and Sweden) the appliance must be connected to a grounded outlet.

 Note

Statement 1101 is applicable to AC units only.

 Note

Grounding the chassis is required, even if the rack is already grounded. A grounding pad with two threaded holes is provided on the chassis for attaching either a grounding lug or a grounding plate used to attach the ground lug to the chassis. The ground lug must be Nationally Recognized Testing Laboratory (NRTL)-listed. In addition, a copper conductor (wires) must be used and the copper conductor must comply with NEC for ampacity.

 Note

When terminating the frame ground, do not use soldering lug connectors, screwless (push-in) connectors, quick connect connectors, or other friction-fit connectors.

Connect the switch to the ground

To establish an earth ground for the chassis, you must attach a grounding cable from the chassis’ grounding lug to the rack.

Step 1

Use a wire-stripping tool to remove approximately 0.75 inches (19 mm) of the covering from the end of the 6 AWG 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 (6 AWG cable) in the grounding lug.

Step 4

Attach the grounding cable:

Position the grounding lug against the grounding plate or the grounding point on the chassis to ensure solid metal-to-metal contact. Insert the provided screws through the holes in the grounding lug and into the grounding plate or grounding point.

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.

Install the rack

Before you install the switch, you must install a standard four-post, 19-inch EIA data center rack (or a cabinet that contains such a rack) that meets the requirements.

  • Install the switch in these types of cabinets and racks, assuming an external ambient air temperature range of 0 to 104°F (0 to 40°C):
    • Standard perforated cabinets
    • Solid-walled cabinets with a roof fan tray (bottom to top cooling)
    • Standard open racks

If you are using an enclosed cabinet, we recommend that you use one of the thermally validated types, either standard perforated or solid-walled with a fan tray.

We do not recommend using racks that have obstructions (such as power strips). The obstructions could impair access to field-replaceable units (FRUs).

Safety warnings

Adhere to these safety warnings before you rack mount the switch.

 Warning

 Warning

Statement 1074—Comply with Local and National Electrical Codes

To reduce risk of electric shock or fire, installation of the equipment must comply with local and national electrical codes.

Install a 4-post rack

This section describes how to install the standard four-post rack.

Step 1

Bolt the rack to the concrete subfloor before moving the chassis onto it.

  1. Determine which end of the chassis is to be located in the cold aisle.

Step 2

If the rack has bonded construction, connect it to the earth ground. This action enables you to easily ground the switch and its components and to ground your electrostatic discharge (ESD) wrist strap to prevent damaging discharges when you handle ungrounded components before installing them.

Step 3

Include one or two power sources at the rack. For AC power, provide a power receptacle.

Step 4

Include one or two power sources at the rack. For DC power, provide a circuit breaker with terminals for connecting power cables.

If you are not using power redundancy or are using n+1 redundancy, you need only one power source. If you are using n+n redundancy, you need two power sources.

  1. Position the guide rails at the desired levels on the back side of the rack and use four 12-24 screws or four 10-32 screws, depending on the rack thread type, to attach the rails to the rack.
     Note
    For racks with square holes, you may need to position a 12-24 or 10-32 cage nut behind each mounting hole in a guide rail before using a 12-24 or 10-32 screw.
  2. Repeat Step 3a to install the guide rails on the other side of the rack.
  3. Use a tape measure and level to verify that the rails are horizontal and at the same height.

Step 4

Insert the switch into the rack and attach the switch.

  1. Hold the switch with both hands, position the back of the switch between the front posts of the rack.
  2. Align the two rack-mount guides on either side of the switch with the guide rails installed in the rack. Slide the rack-mount guides onto the guide rails, and gently slide the switch all the way into the rack.
     Note

    If the switch does not slide easily, try realigning the rack-mount guides on the guide rails.

  3. Hold the chassis level, insert two screws (12-24 or 10-32, depending on the rack type) through the holes in each of the rack-mount brackets and into the cage nuts or threaded holes in the rack-mounting rail.
  4. Tighten the 10-32 screws to 20 in-lb (2.26 N.m) or tighten the 12-24 screws to 30 in-lb (3.39 N.m).
