HARDWARE INSTALLATION

Note:

A cable for the global indicator comes with your computer

system. Cables for the individual drive LEDs may come with a

drive cage or you may need to purchase them.

The intelligent LED controller outputs a low-level pulse to deter-

mine if status LEDs are attached to pin sets 1 and 2. This allows

automatic controller conguration of the LED output. If the logi-

cal level is different between the st 2 sets of the HDD LED header

(LED attached to Set 1 but not Set 2), the controller will assign the

rst HDD LED header as the global indicator connector. Otherwise,

each LED output will show only individual drive status.

The SATA RAID controller provides four kinds of LED status connec-

tors.

A: Global indicator connector, which light up when any drive is ac-

tive.

B: Individual LED indicator connector, for each drive channel.

C: I

C connector, for SATA proprietary backplane enclosure.

D: SGPIO connector for SAS backplane enclosure

The following diagrams and description describes each type of con-

nector.
