Power and Grounding
The following sections provide details on how to connect AC power to the switch, grounding the chassis, and how to power-on the
switch.
Switch Power Supply
The switch requires power from an external AC power supply that can meet the required specification described below.
Active power requirements:
AC Input Power: 100-240V, 50-60Hz, 2.1A
Total Power consumption: 160W
NOTE:
Maximum power consumption values are measured under a 100 percent loading test and should be used as estimates for
planning purposes.
A standard AC power socket is located on the rear panel of the switch. The power socket is for the AC power cord.
Grounding the Chassis
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.
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.
Connecting 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:
AC 100-240 V, 50-60 Hz, 2.1 A
To connect the switch to a power source:
1.
Plug the power cord into a grounded, 3-pin, AC power source.
2.
Insert the plug on the other end of the power cord directly into the AC input socket on the back of the switch (see FIG. 10).
NOTE:
If your country's AC power outlet standards do not match the power plug of the included AC power cord, you will need to
change the AC power cord. You must use a cord set that has been approved for the socket type in your country.
3.
Check the LED indicators on the switch front panel as the unit is powered on to verify that power is being received. If not,
recheck the power cord connections at the AC supply source and back panel power input connector.
