2. Plug in all cables to the SAS I/O module.
IMPORTANT: You must install the SAS I/O cables in the same slots from which they were
removed or the system might fail.
3. Verify that the replacement SAS I/O module is working properly by checking the overall
module status LED (“SAS I/O module LEDs status” (page 54)).
NOTE: The green overall module status LED should turn on within five seconds after the new
module is inserted in the system, which reflects the necessary time to boot the firmware.
