Step 1: Before connecting the AC power cable, ensure that the ES4710BD is properly
grounded and the output switch of the power supply module in the AC distribution box is
off.
Step 2: Insert one end of the three power cables into the power source socket (dedicated branch
circuits are recommended), and the other end to the power socket in the switch
distribution box. Fix the cables with the wiring clips.
Step 3: Check the power status indicator in the front panel of the main control switch module. The
corresponding green Power OK indicator should be illuminated. If any Power OK
indicator is not illuminated, please verify that the corresponding power source socket is
powered and the power supply module is in position and locked securely. If any yellow
Power Fail indicator is illuminated, please replace the corresponding power supply
module immediately.
Step 4: Turn on the power output switch in the distribution box, verify the power status indicators
in the front panel of the main control switch module and in all line cards. The
corresponding Power OK green indicator should be illuminated for power of the supply
slot with a power supply module. All green PWR indicators in each card should also be
illuminated. If any yellow Power Fail indicator is illuminated, please switch off the power
immediately and replace the corresponding power module; if the green PWR indicator in
any cards is not illuminated, please verify the card has been properly inserted and locked.
Connection procedures for DC power supply module are described below:
Step 1: Before connecting the DC power cable, ensure that the ES4710BD is properly grounded,
and the air switch in the DC distribution box is off.
Step 2: Connect the -48 V DC power cable securely to the wiring post in the distribution box, not
the polarity.
Step 3: Turn on the air switch in the distribution box, verify the power status indicators in the front
panel of the main control switch module and in all line cards. The corresponding Power
OK green indicator to power the supply slot with a power supply module should be
illuminated, and all green PWR indicators in each card should be illuminated. If any
Power OK indicator is not illuminate, please verify that the power module has been
properly inserted into the corresponding power supply slot and locked properly. If all
Power OK indicators are not illuminated, please turn off the air switch immediately and
verify that the DC power cable is securely connected to the wiring post with the right
polarity, and the DC power source cable is powered. If any yellow Power Fail indicator is
illuminated, please turn off the air switch immediately and replace the corresponding
power module; if the green PWR indicator in any cards is not on, please verify the card
has been properly inserted and locked.
If the Power OK indicator does not illuminate after repeating the above steps, please contact the
