Prerequisites
Procedure steps
Passport 15000, 20000 Hardware Installation, Maintenance, and Upgrade
Check the final status of all LEDs to verify the equipment is operating before
putting the Passport 15000 or 20000 and all interworking equipment into
service.
• You must be familiar with "Safety considerations and best practices"
(page 53).
• When a LED stays solid red after loading is attempted, the card is
— an incompatible vintage
— was previously loaded with software that is incompatible with the
current software running on the switch
— has failed
• The 241-5701-520 Passport 7400, 15000, 20000 Troubleshooting and
Testing can help you with identifying possible reasons why the hardware
is not initiating properly.
1 On the Passport 15000 or 20000, verify that at least one LED is lit on each
hardware part that has LEDs. If no LED is lit on a part after powering up,
then one or more of the following conditions prevails:
• the green LED is burned out and software can verify if the part is
actually operational
• there is a problem in a cable assembly or a connection between the
BIP and the PIMs
• there is a problem with one of the power feeds to the BIP, but this
means a series of hardware LEDs would not be lit
• there is a problem in the backplane of the shelf
2 On a Passport 20000, press the LED Test button on the front of the alarm
module. Verify that all LEDs on the following hardware parts light up for
approximately ten seconds:
• the BIMs and alarm module of the BIP
• the cooling unit or units
