Component Locations

In Figure 1, the components on the front panel are shown. Use this illustration to locate front-panel features and components discussed later in this manual.

Figure 1. Front-Panel Component Locations

1 LS module (2) 2 1-inch hard-disk drive carriers (14) 3 Handle on front-panel mounting flange (2) 4 Thumbscrew (2)

CAUTION: Do not use front-panel handles to lift the chassis. Handles are for sliding the chassis in and out of the rack on rack rail assemblies.

The two hot-swappable loop resiliency circuit/SCSI enclosure services (LS) modules provide active/passive failover of enclosure services as well as monitoring and control of Fibre Channel loops. Each LS module has six light-emitting diodes (LEDs) for indicating system power, system fault, FC loop A and loop B status, and LS module fault. The bottom LED is reserved for future use.

The hard-disk drive bays provide space for up to 14 one-inch FC hot-swappable hard-disk drives. These hard-disk drives are connected to either one or two Dell Fibre Disk RAID Controllers on the back of the system, or to a copper or fibre optic I/O module.

Figure 2. Back-Panel Component Locations

The two option slots accept one or two of the following:

• Dell Fibre Disk RAID Controller module (the first RAID controller must be installed in slot 0 on the right side, as viewed from the back)
  
  
• Copper conductor high-speed serial data connector (HSSDC) module
  
  
• 1-Gb/s fiber optic I/O expansion module

The power cables leading from the power supply distribute power to the system board 
and all installed drives.

¹ When the ready indicator is lit, it shows that the drive is ready for access. A
   flickering ready light shows that the drive is being accessed. The light is 
   controlled by the disk drive.
