Installing the Fabric Interconnect

c) Holding the chassis level, insert screws (12-24 or 10-32, depending on the rack type) in each of the two

front rack-mount brackets (using a total of six screws) and into the cage nuts or threaded holes in the

vertical rack-mounting rails (see the following figure).

d) 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).

Step 5

If you attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility

ground.

Grounding the Fabric Interconnect

The fabric interconnect chassis is automatically grounded when you properly install the fabric interconnect

in a grounded rack with metal-to-metal connections between the fabric interconnect and rack.

Note

You can also ground the chassis, which is required if the rack is not grounded, by attaching a customer-supplied

grounding cable. Attach the cable to the chassis grounding pad and the facility ground.

Warning

An electrical conducting path shall exist between the product chassis and the metal surface of the enclosure

or rack in which it is mounted or to a grounding conductor. Electrical continuity shall be provided by using

thread-forming type mounting screws that remove any paint or non-conductive coatings and establish a

metal-to-metal contact. Any paint or other non-conductive coatings shall be removed on the surfaces between

the mounting hardware and the enclosure or rack. The surfaces shall be cleaned and an antioxidant applied

before installation.

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.
