Chapter 6 Checking LEDs

The I/O expansion module LEDs and their color definitions are shown in Table 6-5.

An SFP link status (L) LED is off if there is no connection or a failed 

connection to this SFP.

and disk ports

Off – Not busy (no I/O activity)
Blinking green – Busy (active I/O)

Status of I/O 
module

Solid green – Power-up successful and SES 
chip has successfully read on-board 
temperature and voltage sensors
