Each host/target interface kit requires an associated cable set chosen from the following

CMI (default) or Mini-SAS HD x4 copper cables:

  • 1m, 2m, 3m

Mini-SAS HD x4 fiber cables:

  • 5m, 10m, 15m, 25m, 50m, 75m, 100m

Cables needed for PCIe links:

  • x4 (1 cable)
  • x8 (2 cables)
  • x16 (4 cables)

Three 120mm x 38mm fans mounted to the front bezel of the chassis

250CFM fixed-speed fans

Tachometer monitoring via front panel LED

Can cool cards up to 3000W (combined)


Dual load-sharing power supplies pluggable from the rear of the chassis:

Two 2000W 80Plus Titanium efficiency power supplies with dual IEC C14 AC input connectors

Total output power:

1000W: 100-127Vac / 12.5-9.5A / 50-60 Hz

1800W: 200-220Vac / 10-9.5A / 50-60 Hz
