Enclosure subsystem The SMC - Storage Array design concept is based on an enclosure subsystem together with a set of plug-in modules and (as supplied) consists of: v An enclosure chassis with: – A backplane PCB – An enclosure management PCB –...
Figure 4. Enclosure subsystem front view 1 Front panel 2 Drive bays 3 Rack retaining screw 4 Rack retaining screw Enclosure chassis The chassis is installed with 48.26-cm (19-inch) rack-mounting features, which enable it to be installed to standard 48.26-cm (19-inch) racks. One chassis occupies two units of rack space (3.5 inches or 8.89 cm high).
8.89-cm (3.5-inch) form factor drive. In addition, two 6.35-cm (2.5-inch) boot drives can be installed in the boot drive module. Note: A bay is defined as the space required to house a single 2.54-cm (1.0-inch) high 8.89-cm (3.5-inch) disk drive in its carrier module (limitation of 1 TB size).

Figure 9. Power supply unit Power supply unit voltage operating ranges are nominally 100V - 240V AC, selected automatically. The PSU has an audible alarm to indicate a fault state and a bi-color (green/red) LED to indicate PSU status. Power supply output connectors The power supply output connectors provide the following outputs: v P1 server board main power connector (1 x 24 pin) v P2 processor power connector (8 pin)
Figure 10. Cooling fan Airflow is front to rear with cooling air being drawn across the drives, through the fans and pressurizing the rear of the enclosure. The pressurized rear allows the PSU to draw the air that it requires; perforations at the rear of the chassis allow cooling air to flow over the processor heatsinks, server board and PCI cards.
Figure 11. Driver carrier module Drive status indicator Disk drive status, under ESI processor control, is monitored by two LEDs (a green LED and an amber LED) mounted on the front cap of each drive carrier module. See “Disk drive LEDs” on page 21 for a description of LED states. Figure 12.
Figure 13. Drive bay numbering The SMC - Storage Array subsystem is housed in a 4 x 3 enclosure (four drive bays wide by three bays high). The top bays are numbered 1 to 4 from left to right, as viewed from the front.
Figure 14. Unpacking the SMC - Storage Array Planning and configuring your installation Refer to “Planning your installation” on page 13 for information on overall system configuration requirements. Refer to the Secure Managed Client (SMC) - Storage Array Setup Poster that shipped with your system for instructions on installing the processors, drives, and memory.
CAUTION: Operation of the enclosure system with any modules missing will disrupt the airflow and the drives will not receive sufficient cooling. It is essential that all openings are filled before operating the unit. Installing the enclosure in a rack A set of rack-mounting rails is provided with the system for installing the SMC - Storage Array in a 48.26-cm (19-inch) rack cabinet.
7. Return enclosure to fully home position and attach to rack using captive fasteners on front flanges. Note: Rack rails have features to restrict complete enclosure withdrawal while still allowing access to the cooling fans. If it becomes necessary to completely remove the system, pull the enclosure out until it stops then rotate the latches, shown in Figure 15 (right hand up, left hand down), to completely remove the enclosure from the rack.
Front operator's panel LEDs and switches The front operator’s panel LED fault and status conditions are defined in Table 4. Functions of the push-button switches are defined in Table 5. Figure 18.

Starting the drives Unless otherwise selected during installation, all drives in the enclosure should automatically start their motors during power on. If this does not occur then one of the following conditions may exist: v There may be a power problem (an alarm and power fault indication would normally be present).
1. Carefully insert the TORX screwdriver provided into the cutout in the handle (see 1 in Figure 20). 2. Rotate the screwdriver in an anti-clockwise direction until the lock symbol is no longer visible in the opening beside the key (see 2 in Figure 20). Note: Do not turn the lock more than half a turn;...

Cooling fan LEDs An amber LED incorporated in each cooling fan monitors its status. Constant On indicates a fault condition. . Drive carrier module LEDs Disk drive status is monitored by a green LED and an amber LED mounted on the front of each drive carrier module.

CAUTION: Observe all conventional ESD precautions when handling modules and components. Avoid contact with backplane components and module connectors, etc. Note: The top cover of the enclosure covers a service area which should be accessed only by qualified service personnel. When the cover is replaced it must be secured by turning the lock mechanism to the locked position.
