Verfying correct electrical grounding

Do the following to verify correct electrical grounding:

Improper chassis grounding may impair the operation of the STM-1 electrical interface, thereby causing data transmission errors on the STM-1 link.

1.Inspect the rack chassis grounding studs on the AC power module or DC power module (see figure 11 for studs locations) to ensure a #12 AWG ground wire is attached.

Figure 11. AC power module and DC power module grounding studs locations

2.Inspect the remote end the #10 AWG ground wire and verify that it is attached to one of the following grounding sources:

The building ground rod (generally located at the site’s main service entrance)

A sprinkler system pipe

A cold-water pipe

Building structural steel

Verifying correct cover plate installation

Missing front or rear panel cover plates leave the chassis interior open and vulnerable to the following problems:

Impaired EMI shielding against incoming and outgoing electromagnetic signals

Reduced chassis cooling system efficiency, which can resulting in equipment overheating, especially in the SHD laser subsystem on the Matrix Switch

Do the following to verify that cover plates are properly installed:

1.Inspect the front of the chassis and verify that a cover plate is installed for each vacant module slot, and verify that each cover plate’s fasteners are tightened securely to the front panel. Missing cover plates must be replaced before installing the Matrix Switch.
