Rear Panel Components

007-4377-002
The IX-brick has the following rear panel components (see Figure 6-4):
• Power switch. Moving the power switch to the
controller of the IX-brick, and moving it to the
controller. The 12-VDC LED illuminates green when the L1 controller is powered
on.
• 12-VDC LED. The 12-VDC LED illuminates green when the L1 controller is
powered on and operating. The L1 controller is powered on by turning on the
power switch.
• 48-VDC LED. The power switch must be in the ON (
light. The 48-VDC LED illuminates green when the rest of the IX-brick internal
components are powered on and operating. The rest of the internal components are
powered on by pressing the On/Off switch on the front panel of the brick, or via the
L2 controller display or system console.
• PWR (power) connector. This connector connects to a power bay, which provides
power to the IX-brick.
• PCI-X slots. These slots seat the PCI cards. See "Adding or Replacing a PCI or
PCI-X Card" on page 136. The card slots are numbered bus 1 through bus 6. Each
bus has two slots, labeled 1 and 2, as shown in Figure 6-4.
• PCI-X slot LEDs. Each PCI-X slot has the following LEDs:
– PWR (power) LED. This LED illuminates green when the PCI card is installed
securely and is getting 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 IX-brick to one
C-brick. As an option, the second connector can be connected to another C-brick to
create a dual-ported IX-brick, which would provide greater bandwidth.
• XIO 10 and XIO 11 connector LEDs. Each XIO connector has two LEDs, as follows:
– The yellow LED illuminates to indicate that both the IX-brick and the brick to
which it is connected are powered on.
– The green LED illuminates when a link has been established between the
IX-brick and the brick to which it connects.
• Two DB-9 RS-232 serial port connectors. These ports can be used as COM ports to
connect to serial devices. They require the presence of the base I/O card.
