Removing a DC Power Supply Cable from the SRX1500 Services Gateway
To remove a power supply cable connected to a DC power supply:
1.
Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect
the strap to an approved site ESD grounding point. For more information about ESD,
see
“Preventing Electrostatic Discharge Damage to the SRX1500 Services Gateway”
on page 118 .
2.
Switch off the external circuit breakers for all the cables attached to the power supply.
Make sure that the voltage across the DC power source cable leads is 0 V and that
there is no chance that the cables might become active during the removal process.
3.
Remove the power cable from the DC power source.
4.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis. For more information about ESD, see
“Preventing
Electrostatic Discharge Damage to the SRX1500 Services Gateway” on page 118 .
5.
Make sure the cable is not touching or in the way of any services gateway components
and that it does not drape where people could trip on it.
6.
Remove the clear plastic cover protecting the terminal studs on the faceplate.
7.
Attach the power cable to the DC power source.
8.
Verify that the DC source power cabling is correct. If the power cable is correctly
installed and the power supply is functioning normally, the POWER LED on the front
panel glows solid green.
Removing a DC Power Supply on the SRX1500 Services Gateway
Up to two power supplies can be located at the rear of the chassis on the right side. Each
DC power supply weighs approximately 2.20 lbs (1 kg).
CAUTION: Do not leave a power supply slot empty for more than 30 minutes
while the services gateway is operational. For proper airflow, the power supply
must remain in the chassis, or a blank panel must be used in the empty slot.
NOTE: After powering off a power supply, wait at least 60 seconds before
turning it back on.
