Installing the Breaker Interface Panel for the Ethernet Routing Switch 8010co Chassis
Initial power-up
To power up the 8010co chassis:
1 Set the six circuit breakers on the BIP front panel to the off position (O = Off).
2 Set the switches for all power supplies in the upper and lower chassis to the
off position (O = Off).
You can access the power supply switches with the bezels installed.
3 Turn on the input feed power at the DC power source.
Verifying the LEDs
1 Verify the following LEDs on the BIP:
— The (white) POWER Indicator on the BIP front panel is on.
— The (green) shelf alarm cable validation LED is on steady.
The green shelf alarm cable validation LED indicates that the shelf alarm
cables are installed properly.
(If there is a problem with the shelf alarm cable installation or jumper
settings, the red shelf alarm cable fault LED turns on.)
2 Set the six circuit breakers on the BIP front panel to the on position (| = On).
3 Set the switches for all power supplies in the upper and lower chassis to the on
position (| = On).
Danger: Due to high-energy hazards, only qualified service personnel
are permitted to connect the BIP to the DC power source.
Note: When you first install a 8010co chassis that contains two or three
power supplies, you must turn on two of the power supply units
simultaneously. If you wait longer to turn on the second power supply,
one of the power supplies can shut down. To correct this condition, turn
off both power supplies, wait at least 30 seconds, and then turn on both
power supplies again simultaneously.
