Installation Guide
The rear panel of the switch chassis includes a single hole grounding terminal. It must be connected to ground to
ensure proper operation and to meet electromagnetic interference (EMI) and safety requirements.
To ground the switch chassis:
1. Ensure the rack on which the switch is to be mounted is properly grounded and in compliance with ETSI
ETS 300 253.
2. Ensure 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 internally to 0 V. This circuit is connected to the single-hole grounding
terminal on the rear panel of the switch. The surface area around this terminal is not painted in order to
provide for a good connection.
5. Attach a 6 AWG stranded copper wire to the grounding terminal on the switch.
6. Attach the grounding wire to the ground point on the rack.
CAUTION
The earth connection should not be removed unless all power supply
connections have been disconnected.
