About Your New SmartRAID V Controller

SmartRAID V Controller LEDs

SmartRAID V controllers provide nine LEDs that let you visually monitor

controller activity. Several different controller states are indicated by the

LED as outlined in the following sections. Two additional LEDs indicate

the status of the cache memory on the controller. See Appendix A,

“Assembly Drawings” for the location of the LEDs on your controller.

LED Display During Power-Up

During its power-up sequence, the controller passes through the following

states in sequence, as indicated by the LEDs:

Memory Mapped I/O LEDs 6 and 7 and LEDs 5 and 8 flash alternately

while the controller waits for the host computer to

initialize the address translation unit (ATU) on the

PCI bus.

Bridge LEDs 5 and 7 and LEDs 6 and 8 flash alternately

while the controller waits for the host computer to

initialize its PCI-to-PCI bridge.

Fast Idle The controller enters a fast idle pattern while

waiting for the I

O initialization commands after

the address translation unit (ATU) and PCI bridge

have been enabled.

NOTE The ATU, PCI bridge and cache module (if installed) must be

configured and enabled before the I

O initialization can be

completed. If any one of these components are not configured

or become disabled during the Fast Idle phase, the pattern will

return to the respective wait pattern for the affected

component.

LED Display During Controller Idle

When no commands are in progress and all bus activity has ceased, the

controller enters the Idle state. This is indicated by a rotating pattern in

LEDs 1 through 8.
