Installing the hardware
Before beginning the BIP hardware installation, ensure that you:
• Always install the BIP in the uppermost position in the rack to allow for
maximum convection cooling requirements.
• Ground the rack to the same grounding electrode used by the power service in
the area.
The ground path must be permanent and must not exceed 1 ohm of resistance
from the rack to the grounding electrode.
Warning: Ensure that the DC power source is off or disconnected at the
remote end before you perform any of the steps in this section. You may
need to switch a circuit breaker off or turn off power at the DC input
source. Be sure that the DC input source power is locked out and tagged.
Note: The 8004DC power supply operates with the BIP. The BIP does
not support the 8005DC power supply.
