How to Connect to AC Power

Before powering on the switch, ground the switch to earth as described below.
1. Ensure that the rack in 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. Attach a 6 AWG stranded copper wire to the grounding terminal on the switch.
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 (left of the AC
power socket). The surface area around this terminal is not painted in order to
provide for a good connection.
5. 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.
How to Connect to AC Power
Connect the switch to an AC power source to power on. Verify that the external AC
power requirements for the switch can be met as listed below:
ECS2100-10T: AC 100-240 V, 50-60 Hz, 0.5 A
ECS2100-10P: AC 100-240 V, 50-60 Hz, 2.1 A
ECS2100-28T: AC 100-240 V, 50-60 Hz, 0.5 A
ECS2100-28P: AC 100-240 V, 50-60 Hz, 3.2 A
ECS2100-28PP: AC 100-240 V, 50-60 Hz, 5.8 A
ECS2100-52T: AC 100-240 V, 50/60 Hz, 1 A
ECS2110-26T: AC 100-240 V, 50/60 Hz, 1 A
