Server Specifications - Hitachi NAS Platform 4000 Series Hardware Reference Manual

All server models have a chassis that is 3U (5.25 inches) high, 480 millimeters (19 inches)
wide, rack mountable, and a maximum of 686 millimeters (27 inches) deep, excluding the
bezel. The chassis contains:
Front bezel
■
MMB (Main Motherboard)
■
MFB (Main FPGA Board)
■
Model 4040 uses an MFB
●
Models 4060 and 4080 use an MFB2
●
Model 4100 uses an MFB2E
●
Hot-swappable fan assemblies
■
Model 4040 has two fans
●
Models 4060, 4080, and 4100 have dual fans
●
Dual power supplies

If there is an issue with the motherboard (MMB) or field programmable gate array (MFB),
the server must be returned for repair. MMBs are not field replaceable and, typically,
MFBs are not field replaceable). Many of the other components can be replaced in the
field, and some are hot-swappable (they can be changed without shutting down the
server). Field replaceable units (FRUs) include power supplies, an NVRAM backup battery
pack, fan assemblies, and disk drives.
