7. Installing or Removing a Power Supply Unit
The procedure for installing a USF-212PS Optional Redundant Power Supply Unit into a USF frame is
described as follows. Power supply unit replacement can be performed in the same manner.
IMPORTANT
To avoid electric shock, make sure to ground the grounding terminal before operation or pull out the
AC cable from the outlet.
A USF-212PS redundant power supply unit can be installed while the power is on, although the (main)
USF-212S power supply should normally be turned off when doing so. To install or remove a power
supply unit while the power is on, open the front panel. The cooling fan of the unit is turned off when
the front panel is open, so the installation should be completed in a short time to avoid overheating.
Close the front panel immediately after the operation is completed.
