GROUNDING THE CHASSIS

Notes: 1. SFP transceivers are hot-swappable. The switch does not need to be powered off before installing or removing a transceiver. However, always first disconnect the network cable before removing a transceiver.

2.SFP transceivers are not provided in the switch package.

Grounding the Chassis

Before powering on the switch, ground the switch to earth as described below.

1.Ensure that the rack on which the switch is to be mounted is properly grounded and in compliance with ETSI ETS 300 253.

2.Ensure that there is a good electrical connection to the grounding point on the rack (no paint or isolating surface treatment).

3.Disconnect all power cables to the switch.

4.The switch chassis is connected internaly to 0 V. This circuit is connected to the single-hole grounding terminal on the back of the switch. The surface area around this terminal is not painted in order to provide for a good connection. Attach a 6 AWG stranded copper wire to the grounding terminal on the switch.

5.Then attach the grounding wire to the ground point on the rack.

Caution: The earth connection must not be removed unless all supply connections have been disconnected.
