[a] Power supply efficiency needs to be considered if calculating total AC power input.

The following sections provide more details about the I-brick, P-brick, R-brick, and X-brick.

I–brick :

  • Supports a CD-ROM

  • Supports five 64–bit PCI slots to support 3.3/Universal VDC PCI cards (three slots support 33–MHz and two slots support either 33–MHz or 66–MHz PCI cards)

  • Supports two 3.5-in. sled-mounted Fibre Channel disk drives

  • FC disk controller uses one of the PCI slots

P–brick :

  • Supports twelve 3.3/Universal volt PCI cards (all slots support either 33-MHz or 66–MHz PCI cards).

The P–brick power board supplies an average of 17.5 W (5.3 A, 3.3 V) of power to each PCI slot; however, a PCI card may consume as much as 25 W of power. The L1 controller controls how the power board applies power to the PCI cards. Starting with lowest numbered slot, the power board continues to apply power to the PCI cards starting with the lowest numbered slot. It continues to apply power to the PCI slots until all of the power has been consumed. The L1 controller uses two presense pins in each PCI slot to calculate the total power consumption of the PCI cards. The L1 controller prints a message to the console if there is not enough power for all of the PCI cards.

X–brick :

  • Four XIO slots

The power board contains the logic components of the X–brick's L1 controller, five VRMs, one DC-to-DC converter, and three voltage regulators. The VRMs, DC-to-DC converter, and voltage regulators convert the incoming 48 VDC to voltage levels required by the components in the brick.

R–brick :

  • One USB port (connects to L2 controller)

  • Eight NUMAlink I/O connectors (located in rear)

  • Input power is +48 VDC (~60 W)
