Step 5-4. Connect the Min SAS 4i to Multi-lance cable Model ARC-1231ML/1261ML/1280ML have Min SAS 4i internal connectors, each of them can support up to four SATA drives. These controllers can be installed in a server RAID enclosure with a Multi- lance connector (SFF-8470) backplane. Multi-lance cables are not included in the ARC-12XXML package. If you have not already connected your Min SAS 4i to Multi- lance cables, buy the Min SAS 4i to Multi-lance cables to fit your enclosure. And connect your controller to the Multi-lance connector backplane. The type of cable will depend on what enclosure you have. The following diagram shows one example picture of Min SAS 4i to Multi-lance cable. Unpack and remove the PCI RAID cards. Inspect it carefully. If anything is missing or damaged, contact your local dealer. Figure 2-16, Min SAS 4i to Multi-lance HARDWARE INSTALLATION Step 5-5. Connect the Min SAS 4i to Min SAS 4i cable Model ARC-1230ML/1260ML/1280ML have Min SAS 4i internal connectors, each of them can support up to four SATA drives. These adapters can be installed in a server RAID enclosure with a Min SAS 4i internal connector backplane. Min SAS 4i cables are not included in the ARC-12XXML package. This Min SAS 4i cable has eight signal pins to support four SATA drives and six pins for the SGPIO (Serial General Purpose Input/ Output) side-band signals. The SGPIO bus is used for efficient LED management and for sensing drive Locate status. Please see page 51 for the details of the SGPIO bus. Unpack and remove the PCI RAID cards. Inspect it carefully. If anything is missing or damaged, contact your local dealer. Figure 2-17, Min SAS 4i to Min SAS 4i Step 6 Install the LED cable (optional) ARC-1XXX Series Fault/Activity Header Intelligent Electronics Schematic. HARDWARE INSTALLATION The intelligent LED controller outputs a low-level pulse to determine if status LEDs are attached to pin sets 1 and 2. This allows automatic controller configuration of the LED output. If the logical level is different between the fist 2 sets of the HDD LED header (LED attached to Set 1 but not Set 2), the controller will assign the first 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 connectors. A: Global indicator connector, which lights when any drive is active. B: Individual LED indicator connector, for each drive channel. C: I2C connector, for SATA proprietary backplane enclosure. D: SGPIO connector for SAS Backplane enclosure The following diagrams and description describes each type of connector. 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. A: Global Indicator Connector If the system will use only a single global indicator, attach the global indicator cable to the two pins HDD LED connector. The following diagrams show the connector and pin locations. Figure 2-18, ARC1110/ 1120/1210/1220 global LED connection for Computer Case.

B: Individual LED indicator connector Connect the cables for the drive activity LEDs and fault LEDs between the backplane of the cage and the respective connector on the SATA RAID controller. The following describes the fault/activity LED. LED Normal Status Problem Indication Activity LED When the activity LED is illuminated, there is I/O activity on that disk drive. When the LED is dark, there is no activity on that disk drive. N/A Fault LED When the fault LED is solid illuminated, there is no disk present. When the fault LED is off, that disk is present and status is normal. When the Red LED is slow blinking (2 times/sec), that disk drive has failed and should be hot-swapped immediately. When the activity LED is illuminated and Red LED is fast blinking (10 times/sec) there is rebuilding activity on that disk drive.

This can reduce the number of activity LED and/or fault LED cables. The I2C interface can also cascade to another SATA ba...
