Rack Power Consumption

The tall rack comes with a 220-V power distribution unit (PDU); the short rack comes with either a 120-V PDU or a 240-V PDU. The PDU is rated as shown in Table A-2.

Thermal Dissipation

Each node in the SGI Graphics Cluster has two system fans. Each processor in each node also has its own fan. The SGI Graphics Cluster Series 11 has one processor with a fan; the SGI Graphics Cluster Series 12 has two processors, each with a fan.

A fully configured SGI Graphics Cluster in a tall rack under maximum workload (1,305 W) can produce approximately 4,450 Btu/hour, requiring 0.3708 tons of cooling.

Air temperature measurements around the rack may vary.

Ethernet Port

An SGI Graphics Cluster node has an RJ45 port for 10-Base-T or 100-Base-TX twisted-pair Ethernet. The port autoselects the speed (10 Mbps or 100 Mbps) and type (half-duplex or full-duplex) at bootup, based on what it is connected to. Figure A-6 shows the Ethernet port.

Audio Ports

The audio on the node motherboards is disabled in the SGI Graphics Cluster. The master node of the SGI Graphics Cluster Series 12 has a commercial audio card.

An SGI Graphics Cluster node uses a 3.5 mm mini jack stereo microphone port, an analog line-level audio input port, and an analog line-level audio output port.

For use with the audio card ports on the master node of an SGI Graphics Cluster Series12, SGI supports audio cables no longer than 3 meters. For uses requiring cables longer than 3 m, you can convert to balanced audio using an unbalanced-to-balanced converter such as Balance Buddy from Rane Corporation or FP-UBC2 from Radio Design Labs, or do active conversion to AES digital audio.

For port information for the sound card on the SGI Graphics Cluster Series12 master node, see the manufacturer's manual for the product, which is a SoundBlaster Live! Value sound card. You can download the manual for this card free from the manufacturer's web site, http://www.soundblaster.com.
