3. Ground the Switch
Ensure the rack on which the switch is to be mounted is
properly grounded and in compliance with ETSI ETS 300 253.
Verify that there is a good electrical connection to the
grounding point on the rack (no paint or isolating surface
treatment).
Attach an 18 AWG minimum grounding wire (not included)
to the grounding point on the switch rear panel, and then to
rack ground.
Caution:
The earth connection must not be removed
unless all supply connections have been disconnected.
4. Connect Power
a. AC Power
Plug the power cord into a 100-240 VAC, 50-60 Hz AC power
source.
Insert the other end of the power cord directly into the AC
input socket on the back of the switch.
b. DC Power
Warning:
Before wiring the DC plug or connecting power
to the switch, ensure that power to the feed lines are turned
off at the supply circuit breaker or disconnected from the
power bus.
Warning:
This unit is intended to be supplied by a IEC/UL
listed DC power source suitable for whose input is rated DC
-48 to -60V, 3.0 A.

The ECS4120-28F/ECS4120-28F-I /ECS4120-28Fv2/ECS4120-
28Fv2-I switch supports the option of connecting an
external -48 to -60 VDC power source to its DC terminal
block.
Connect the -48 VDC power feed wire to the DC plug “-” pin.
Connect the ground/return wire to the DC plug “+” pin.
5. Verify Switch Operation
Verify basic switch operation by checking the system LEDs.
When operating normally, the following LEDs should be on
green:
◆
28T/28P/52T: DIAG
◆
28F/28F-I/28Fv2/28Fv2-I: PWR and DIAG
6. Perform Initial Configuration
Connect a PC to the switch console port using the included
console cable.
Configure the PC’s serial port: 115200 bps, 8 characters, no
parity, one stop bit, 8 data bits, and no flow control.
Log in to the CLI using default settings: Username “admin”
and password “admin.”
Note:
For further information on switch configuration,
refer to the Web Management Guide and CLI Reference
Guide.
