•
(3) UID (Unit ID) switch: Set this switch to ON/OFF to control the UID LED on the front of
the device. When processing the switch once, UID LED lights and it goes off when pressing it

(7) System POWER LED: This LED illuminates green when one of the power supplies of the
CPU/IO modules is ON. The LED goes off when both power supplies of the CPU/IO module
are OFF.
•
(8) System FAULT LED: When one of the CPU/IO modules has an error, this amber LED
lights. Details can be confirmed by checking EXPRESSSCOPE. The amber LED lights when it
cannot identify which one of the CPU/IO modules has an error.
•
(9) System FT LED: This LED displays the device status. This green LED lights when operating
under a duplex condition. The LED goes off if it's not duplex. This green LED also lights when
executing an Active Upgrade.
•
(10) System ID LED: The blue system ID LED lights on the front bezel if pressing UID switch
when there are multiple devices installed in one rack. This enables the user to identify the device

PCI board, cooling fan unit, and hard disk drive components identical to CPU/IO module 0.
•
(14) EXPRESSSCOPE various LEDs (green/amber): This LED indicates the status of CPU/IO
modules.
•
(15) SLIDE-TAG: A Label where N-Code and Serial number are printed is pasted to this tag.
ExpressScope LEDs
On the front of the FT server with the front bezel removed, the EXPRESSSCOPE LEDs (amber)
can be accessed to determine if either CPU/IO module has failures. The LEDs on the upper line
correspond to the upper names and the LEDs on the lower line correspond to the lower names.
NOTE: If any component has failed in a CPU/IO module including DIMMs and the power
supply, the entire CPU/IO module is replaced. All hard disk drives should be labeled for slot
location, then removed from the faulty unit. When a replacement module is received, the hard
disk drives should be replaced into the same slots to maintain the mirrored images.
