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 – A SAS expander PCB, to branch from 4 to 12 SAS ports, supporting SATA tunnelling protocol – A front operator's panel – An integral rear panel, incorporating an enclosure ID LED – A power supply mounting cage containing one 850-W plug-in power supply unit (PSU) Note: A
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). Figure 5.
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). At the rear, the chassis assembly accommodates one PSU and a server board subsystem. A top cover on the enclosure provides access to the cooling fans and the server board subsystem.

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.
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. The cooling system must be operated with low-pressure rear exhaust installation (back pressure created by rack doors and obstacles not to exceed 5 pascals [0.
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.

Chapter 3. Getting Started In this chapter, you are shown how to plan and install your Secure Managed Client (SMC) - Storage Array into an industry standard 48.26-cm (19-inch) rack cabinet. CAUTION: When connecting the SMC - Storage Array, use only the power cords supplied or power cords that match the specification quoted in the Safety and Warranty Guide.
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. Drive carrier module locations are identified from a matrix of the top and side numbers. Enclosure installation prerequisites The SMC - Storage Array is delivered fully populated with 12 drive carrier modules pre-installed. Notes: 1.
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. Rack installation prerequisites The SMC - Storage Array is designed for installation into an industry standard 48.
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.

Chapter 4. Operation Before powering on the Secure Managed Client (SMC) - Storage Array ensure that all modules are firmly seated in their correct bays. Power on Apply AC main power to power on the enclosure. The power active LED on the front operator’s panel will light up green once power is activated. The disk drive motors will also start running. CAUTION: Do not operate the SMC - Storage Array until the ambient temperature is within the specified operating range.
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. Front operator’s panel components 1 USB port 2 Power active LED 3 Unit fault LED 4 ID LED 5 On/off switch 6 Reset button (recessed) 7 ID LED activation switch Table 4.
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). v The drive motors will spin up in a delayed sequence. Disk drive LEDs Each drive carrier module has two LEDs, an upper (green) LED and a lower (amber) LED.
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; otherwise, the drive carrier may be damaged. 3. Remove the screwdriver. Figure 20.
Chapter 5. Troubleshooting and problem solving The Secure Managed Client (SMC) - Storage Array includes an enclosure services processor and associated monitoring and control logic to enable it to diagnose problems within the enclosure’s power, cooling and drive systems. The sensors for power and cooling conditions are housed within the PSUs and cooling fans. There is independent monitoring for each unit.

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. The conditions for each LED are defined in “Drive carrier module faults” on page 30. Rear panel LED Table 8.

A Voltage Out Of Range condition will activate the audible alarm.
Table 11. Light and buzzer interpretations (continued) LED/buzzer State Related Fast blink (alternating Faster beep (1.5 every half second) seconds beep, 0.5 seconds silence). No fan light constant. No beep if muted. Constant on Meaning Action Critical state - usually temperature near edge of operating range Check ambient temperature and increase if too cold or decrease if too hot immediately. If this does not work, check for a fan failure that also has a broken light.

Cooling fan faults Table 14. Cooling fan faults Symptom Cause Action 1. Front panel fault LED amber 1. Any power fault 2. Audible alarm sounding 2. A fan failure 1. Check to ensure DC power to cooling fans is correct and that the LED is not illuminated 3. Fan LED is illuminated 2. Disconnect the PSU from main power and remove the faulty fan from the system. Re-install. If problem persists, replace PSU. 3.
Table 15. Thermal cooling (continued) Symptom Cause Action 1. Front operator's panel unit fault LED amber. If the internal temperature measured in the airflow through the enclosure exceeds a pre-set threshold, a thermal alarm sound. 1. Check to ensure that local ambient environment temperature is below the upper 35°C (95°F) specification. 2. An amber LED is lit on one or more PSUs. 2. Check the installation for any airflow restrictions at either the front or rear of the enclosure. A minimum gap of 2.
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.
