Powering On a DC-Powered SRX5400 Services Gateway
To power on a DC-powered services gateway:
1.
Verify that an external management device is connected to one of the Routing Engine
ports (
AUX
,
CONSOLE
, or
ETHERNET
).
2.
Turn on the power to the external management device.
3.
Verify that the power supplies are fully inserted in the chassis.
4.
Verify that the source power cables are connected to the appropriate terminal: the
positive (+) source cable to the return terminal (labeled
RETURN
) and the negative
(–) source cable to the input terminal (labeled
–48V
).
5.
Switch on the dedicated customer site circuit breakers to provide power to the DC
power cables. Follow your site’s procedures.
6.
Check the
INPUT OK
LED is lit steadily green to verify that power is present.
7.
If power is not present:
•
Verify that the fuse is installed correctly and turn on the breaker at the battery
distribution fuse board or fuse bay.
•
Check the voltage with a meter at the terminals of the power supply for correct
voltage level and polarity.
8.
Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
9.
Move the DC circuit breaker on each of the power supplies to the on (
—
) position.
10.
Verify that the
BREAKER ON
LED is lit green steadily.
11.
Verify that the
PWR OK
LED is lit green steadily, indicating the power supply is correctly
installed and functioning normally.
If the power supply is not functioning normally, repeat the installation and cabling
procedures.
NOTE:
After a power supply is powered on, it can take up to 60 seconds
for status indicators—such as the status LEDs on the power supply and
the
show chassis
command display—to indicate that the power supply is
functioning normally. Ignore error indicators that appear during the first
60 seconds.
If any of the status LEDs indicates that the power supply is not functioning normally,
repeat the installation and cabling procedures .
12.
On the external management device connected to the Routing Engine, monitor the
startup process to verify that the system has booted properly.
