Introduction Each controller has three SAS ports (Figure 4): • Use the input ports (HOST 1 and HOST 2) to connect to the host systems. • Use the expansion port (EXP) to connect to another StorageScaler 2460 enclosure. See Section 1.8 for more information. • When using the StorageScaler 2460 in a zoned configuration, the three SAS ports are assigned drives specifically to separate host computers. Please refer to Appendix B for supported zoned configurations.
Introduction NOTE : A disk drive must not be removed from its drive carrier. A disk drive removed from its carrier is not covered by the hardware warranty. NOTE : All SATA disk drives installed in a dual-controller system require the use of a 2:1 SATA MUX assembly. Please contact your DataDirect Networks sales representative to obtain the MUX cards. Each drive carrier has three LEDs, which indicate status as described in Section 3.3, Monitoring the Disk Drives.
Introduction 1.7.1 Maintaining Correct Airflow and Cooling In addition to supplying power, the APC units maintain proper airflow and cooling within the enclosure. Because there are two APC units, the enclosure can continue to operate even if one APC unit fails. The cooling fans in each APC unit run on separate circuits from the power supply. If one APC unit fails, its fans continue to run on power supplied by the other APC unit.
Introduction 1.8.2 Basic Configuration – Dual Controller System Connect your SS2460 enclosure to two SAS/SATA HBAs in a dual host system (Figure 9). Figure 9. StorageScaler 2460 Dual Host System StorageScaler 2460 Enclosure Host 1.8.

Discovery is complete once the drive LEDs stop flashing.
Chapter 3 Monitoring Your SS2460 96-00290-001 Rev.
Monitoring Your SS2460 This chapter describes the status and activity LEDs that help you monitor the DataDirect Networks StorageScaler 2460 enclosure and its components. 3.1 Monitoring the Enclosure On the right side of the front of the SS2460 enclosure are four LEDs which indicate the status of the whole enclosure (Figure 25). The LEDs are defined in Table 1. When a failure occurs on a controller or APC unit, the enclosure LEDs indicate an enclosure fault.
Monitoring Your SS2460 3.2 Monitoring the Controllers Each controller has 11 status LEDs (Figure 26). The LEDs are defined in Table 2. When a fault condition occurs on a controller, the enclosure LEDs indicate an enclosure fault. Because the controllers are on the back of the enclosure where they may be hard to see, always check controller status whenever the enclosure LEDs indicate a fault. When the controller Fault LED illuminates, replace the controller (see Section 4.2). Figure 26.
Monitoring Your SS2460 3.3 Monitoring the Disk Drives Each disk drive carrier has three LEDs that indicate the status of the disk drive (Figure 27). The LEDs are defined in Table 3. NOTE : If replacing a disk drive does not resolve a fault or failure indicated by the Fault LED, replace the I/O controller (see Section 4.2). Figure 27. Disk Drive Carrier LEDs Status Locate Fault Table 3. Disk Drive Carrier LED Description 96-00290-001 Rev.
Monitoring Your SS2460 3.4 Monitoring the APC Units Each APC unit has four LEDs that indicate status (Figure 28) as described in Table 4 below. When a failure occurs on an APC unit, the enclosure LEDs (see Section 3.1) indicate an enclosure fault. Because the APC units are on the back of the enclosure where they may be hard to see, always check the APC unit status whenever the enclosure LEDs indicate a fault. Figure 28. APC Unit LEDs Locate Fault DC OK AC OK Table 4.
