Field Replaceable Units
The Power Supply Module is a field replaceable unit. The repair procedure is to swap in a
new (known good) component to restore system operation.
Replacing a Power Supply Module
The Kaleido-X16 frame is powered by dual redundant, current-sharing power supply units
(PSUs). In the event of a power supply failure, the unit will switch to the redundant power
supply for its power source. If a PSU’s LED is not green, you must replace the unit.
The PSUs are installed and removed from the front of the frame and are hot-swappable, so
that a defective supply may be replaced without removing the Kaleido-X16 frame from
service. When facing the front of the frame, the PSU on the left side is referred to as
PSU A
and the PSU on the right side is PSU B .
Power supply for the Kaleido-X16 frame
Access the power supplies by removing the front cover of the frame. Viewed from the front
of the frame, the PSUs are located on the left-hand and right-hand sides of the frame:
IMPORTANT
If your frame has only one PSU, it must be installed in Slot A (left side of
frame)
There are two power supplies: an operational PSU and a redundant PSU. The
system operates with a single PSU. If you choose to have only one PSU
installed in your Kaleido-X16 frame, you should do the following:
• Clear the PSU B Installed check box for this Kaleido-X16 frame in XAdmin
(see the “Configuring Power Supply Redundancy on the Kaleido-X16”
section in the
Getting Started chapter of the Kaleido Software User’s
Manual; see Related Documentation , on page 15).
• Install the single PSU (PSU A) in Slot A (the left side of the frame when
facing the front of the frame) (see Installing a Power Supply , on page 101).
