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

– 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)

A blanking plate must be installed over the empty upper bay.
v
A server subsystem comprising:
– An Intel Server Board S5000PSL with integral I/O panel
– An Intel RAID Controller SRCSATAWB
– A boot drive module
