in the mounting rails) through the holes in the front rack-mount bracket and into the holes in the
mounting rails, using four screws per side.

System Grounding

This section describes the need for system grounding and explains how to prevent damage from
electrostatic discharge.

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.

The front rack-mount brackets are shipped installed on the switch. If they have been uninstalled,
reinstall them on the switch using the M4 x 6-mm screws.

Because the fan tray is on the left side of the chassis, Cisco recommends using only the right
side for cable management. This allows easy removal of the fan tray if you need to replace a fan.
Use a minimum of four screws per side to ensure that the switch is adequately supported by
the front rack-mount brackets.
