Working with Power Supplies
The ZT 5085 accommodates up to eight 250 W, CompactPCI*, modular power supplies. The
power supplies are load sharing, hot swappable, and plug directly into the power trays (see
Figure 17, “Power Supply Orientation” on page 39
for power supply location).
The number of power supplies needed in any given system depends on the load in that system. It is
recommended that eight power supplies be used in every ZT 5085.
Warning:
The ZT 5085 is configured for either AC or DC input. The system’s power input configuration (AC
or DC) must match the power supply input voltage (AC or DC). DO NOT INSTALL A DC INPUT
POWER SUPPLY IN A ZT 5085 CONFIGURED FOR AC INPUT.
Warning:
Only trained personnel should perform power supply maintenance. When the system is plugged in,
high voltages are present on the midplane. Do not reach into the enclosure.
Warning:
All power supplies must be of identical make and model. If changing make or model, power must
be removed from the chassis and all supplies must be replaced.
Warning:
Air management boards are required in otherwise unpopulated slots. Failure to cover open slots
could cause overheating of power supplies, boards, or other components, and could damage the
system.
