5. Switch on the dedicated customer site circuit breakers. Follow the ESD and safety instructions for your
site.
6. Attach an ESD grounding strap to your bare wrist, and connect the strap to one of the ESD points on
the chassis.
7. Switch the AC switch in the chassis above each power supply to the on (—) position.
8. If the services gateway has high-capacity power supplies installed, you must also move the AC switch
at the top of each power supply to the on (|) position.
9. Verify the following LED indications for each installed power supply:
For standard-capacity AC power supplies, verify that the AC OK and DC OK LEDs light steadily and
the PS FAIL LED is not lit.
For high-capacity AC power supplies, verify that the DC OK LED lights steadily, and the PS FAIL LED
is not lit. In addition, the AC-1 OK LED should light green steadily if the upper AC feed (on the chassis
above the power supply) is connected and receiving power, and the AC-2 OK LED should light green
steadily if the lower AC feed (on the power supply itself) is connected and receiving power.
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.
10. On the external management device connected to the Routing Engine, monitor the startup process to
verify that the system has booted properly.
NOTE: If the system is completely powered off when you power on the power supply,
the Routing Engine boots as the power supply completes its startup sequence. Normally,
the services gateway boots from the Junos OS imageon the CompactFlash card.
After you have powered on a power supply, wait at least 60 seconds before you power
it off.
