Replace a Controller Power Supply
Power supplies, which exist in pairs, provide DC power to all of the Controller
components. If one power supply fails, the other supply carries the full load. This
situation creates a risk of Controller failure should the other power supply also
fail.
A failed Controller can cause data paths to drop.
Prerequisites:
• Deploy any rack anti-tilt mechanism before releasing the release buons and
extending the Controller.
•
Before handling a component, touch a grounded surface to discharge any
static electricity.
• Aach an electrostatic discharge (ESD) wrist strap to your wrist, and stand
on an ESD mat while replacing components.
• Make sure you have a similar replacement power supply available before you
start the replacement procedure.
• Initiate Guided Maintenance only when you are able to replace the power
supplies immediately.
Each Controller has a pair of power supplies that are located at the back of the
Controller. P
ower supplies are customer replaceable units (CRUs). Replacing a
power supply does not require you to bring the Controller oine, provided that
the other power supply is online and working. The following gure identies the
location of the Controller power supplies.
