Power Supplies

The Z9000 is designed to support two hot-swappable power supplies. The Z9000 supports AC and DC
power supplies with two air-flow directions (Normal and Reversed). Two power supplies are required for
full redundancy, but the system will operate with a single power supply.
NOTE: If using a single PSU, you must install a blank plate in the other PSU slot. Dell Force10 recommends
using PSU0, if installing only one power supply.
The Z9000 is orderable as an empty chassis (Z9000P) or with an AC or DC power supply. The Z9000-
AC/Z9000-AC-R system comes from the factory with 1 AC power supply and 4 fan modules installed in
the chassis. The Z9000-DC/Z9000-DC-R system comes from the factory with 1 DC power supply and 4
fan modules installed in the chassis. Power supplies are field replaceable. When running with full
redundancy (2 power supplies installed and running) a power supply unit can be removed and replaced
while the other is running without disrupting traffic.
WARNING:
WARNING: To prevent electrical shock, make sure the Z9000 is grounded properly. If you do not ground your
equipment correctly, excessive emissions may result. Use a qualified electrician to ensure that the power
cables meet your local electrical requirements.
WARNING: Electrostatic discharge (ESD) damage can occur if components are mishandled. Always wear an
ESD-preventive wrist or heel ground strap when handling the Z9000 and its components.

Install a power supply

The power supply units in the Z9000 are field replaceable. When both power supplies are up and running,
one power supply can be removed without interrupting traffic. To remove and replace a power supply
unit, use the following procedure.
CAUTION: Remove the power cable from the modules prior to removing the module itself. Power must not be
connected prior to insertion in the chassis.
WARNING:
WARNING: Prevent exposure and contact with hazardous voltages. Do not attempt to operate this system
with the safety cover removed.
