Powering up a 16-slot Passport switch
Power up a 16-slot Passport switch after you have installed all shelf
components.
Prerequisites
• Verify that all power supply switches are in the standby position. See the
figure “Unlocked power supply with power switch in the standby
position” (page 355).
Procedure steps
1
Disengage all processor cards from the backplane of the shelf
.
2 Engage the minimum number of processor cards required, based on the
number of power supplies in the shelf.
If you have one power supply, engage a CP in slot 0 and at least one FP.
Do not engage more than seven FPs. Ensure that all other processors are
disengaged.
If you have two power supplies, engage at least one CP and two FPs. Or,
engage two CPs and at least one FP.
If you have three power supplies, engage at least one CP and three FPs.
3 Turn on the circuit breakers for the outlets that supply power to your
switch.
4 Verify that the LEDs on all power supplies are red.
5 Apply power to one of the power supplies by setting its power switch to
the on position. See the figure “Unlocked power supply with power switch
in the standby position” (page 355). Verify that the power supply LED is
green.
Normal operation is not guaranteed if there are no processor cards in the
shelf. If you have not installed any processor cards before you switch on
a power supply, the system does not supply power to the shelf and the
power supply LED remains red.
6 Verify that the cooling unit LED is green and is operational. You should be
able to hear the fans start to rotate.
7 If necessary, apply power to a second and third power supply by setting
their power switches to the on position. Verify that the LED for each power
supply is green.
