5: PX-brick
Rear Panel Components
The PX-brick has the following rear-panel components (see Figure 5-4):
•
Power switch.
Moving the power switch to the
1
position powers on the L1
controller of the PX-brick, and moving it to the
0
position powers off the L1
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 (
1
) position for this LED to
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.
