If you have not already done so, confirm that you need to replace the
CP blade before continuing. The following events might indicate that
a CP blade is faulty:
The status LED on the CP blade is lit amber, or the power LED is
not lit.
The CP blade does not respond to Telnet commands, or the serial
console is not available.
The slotShow command does not show that the CP blade is
enabled.
The haShow command indicates an error.
The calendar clock is inaccurate, or the CP blade does not boot up
or shut down normally.
Any of the following messages appear in the error log:
• "Slot unknown" message relating to a CP slot
• CP blade errors or I
• FRU: FRU_FAULTY messages for a CP blade
• Configuration loader messages or "Sys PCI config" messages
• Generic system driver messages ("FABSYS")
• Platform system driver messages ("Platform")
• EM messages that indicate a problem with a CP blade
• Function fail messages for the CP master
For more information about error messages, refer to the Fabric OS
System Error Message Reference Manual.
Back up the switch configuration before you replace a CP blade. Refer
to the Fabric OS Administrator's Guide for backup information.
To record critical switch information:
1. Log in to the healthy CP blade as admin, using either a Telnet or a
serial console connection.
2. Type to determine which CP blade is active:

swDir:admin> haShow
Local CP (Slot 6, CP1) : Active
