Operating the Core Switch 2/64
Determining the Status of the CP Card
To determine the status of a CP card:
Power Supplies
The Core Switch 2/64 uses up to four power supplies, with a minimum of two
required to power a completely loaded chassis. The left power connector provides
power to the power supplies in slots #1 and #3 (color-coded blue), and the right
power connector provides power to the power supplies in slots #2 and #4
(color-coded yellow).
The Core Switch 2/64 can continue operating while a power supply is replaced if
at least one power supply continues operating for every four port cards installed.
A minimum of two power supplies are recommended.

Check the LED indicators on the CP card. For information about how to
interpret the LED patterns, refer to
Check CP card status using the slotshow and hashow commands.For
additional information about these commands, refer to the HP StorageWorks
Fabric OS Version 3.1.x/4.1.x Reference Guide.
Caution:
To protect against AC failure, a minimum of one power supply in
slot #1 or slot #3 and one in slot #2 or #4 is recommended. If only two power
supplies are installed and they are both installed in slots corresponding to the
same power cable, an accidental unplugging of that power cable will power
down the entire chassis. Color coding indicates which AC switches and
connectors correspond to which power supplies.
Before replacing a power supply, determine whether adequate power to keep
the chassis operating will be available throughout the replacement. If not, shut
down both switches before continuing (see
Filler Panel
on page 149). 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 powerOffListSet 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.
