Rear Panel Components

84
The PX-brick has the following rear-panel components (see Figure 5-4):
• Power switch. Moving the power switch to the
controller of the PX-brick, and moving it to the
controller.
• 12-VDC LED. The 12-VDC LED illuminates green when the L1 controller is
powered on.
• 48-VDC LED. The power switch must be in the ON (
illuminate. The 48-VDC LED illuminates green when the rest of the PX-brick
internal components are powered on.
• PWR (power) connector. This connector connects to a power bay, which provides
power to the PX-brick.
• PCI/PCI-X slots. These slots support PCI or PCI-X cards. The card slots are
numbered bus 1 through bus 6. Each bus has two slots, labeled 1 and 2, as shown in
Figure 5-5.
• PCI-X Slot LEDs. Each slot has the following LEDs:
– PWR (power) LED. This LED illuminates green when the PCI card carrier is
installed securely and is receiving power.
– Fault LED. This LED illuminates yellow when a fault occurs with the PCI card.
• XIO 10 and XIO 11 connectors. Each connector can connect the PX-brick to one IP53
node board. As an option, the second connector can connect to another IP53 node
board to create a dual-ported PX-brick, which provides greater bandwidth.
• XIO 10 and XIO 11 connector LEDs. Each connector has two LEDs, as follows:
– The yellow LED illuminates to indicate that both the PX-brick and the IP53
node board to which it is connected are powered on.
– The green LED illuminates when a link has been established between the
PX-brick and the IP53 node board to which it connects.
