Replacing A Power Supply - HP StorageWorks 2/64 - Core Switch Installation Manual

CAUTION:
slot #1 or slot #3 and one in slot #2 or #4. If only two power supplies are installed and they
are both installed in slots corresponding to the same power cable, unplugging a single power
cable will power down the entire chassis.
If adequate power is abruptly lost, such as through removal of a power supply, the entire switch
is powered down; the power off order designated by the powerOffListSet command is not
followed.
Disassembling any part of the power supply voids the part warranty and regulatory
certifications. There are no user-serviceable parts inside the power supply.

Replacing a power supply

Use these steps to replace a power supply. No tools are required.
1. Determine whether power adequate to keep the chassis operating will be available
throughout the replacement. If adequate power will not be consistently available, shut
down the Core Switch 2/64 and SAN Director 2/128 gracefully, as follows:
a. Open a telnet session to the active CP card and log in to the switch as admin.
b. Enter the switchShutdown command.
c. Power off the chassis by flipping both AC power switches to the off position (the 0

a. Orient the power supply so the handle is toward the front of the chassis and the LEDs
are on the left, unlock the handle, and insert the power supply into the slot and push the
handle up until it clicks.
b. Verify that the power supply is seated by pulling gently on the handle.
4. Verify the top LED on the power supply displays a steady green light. If it does not, ensure
both power cables are plugged in and both AC switches are flipped to 1 (AC switch lights
up green).
To protect against AC failure, HP recommends a minimum of one power supply in
Do not force the installation of the power supply. If the part does not install easily,
