The N-brick has the following rear-panel components (see Figure 13-10):
• PWR (power) connector. This connector connects the N-brick to a power bay, which
provides 12-VDC and 48-VDC power to the N-brick.
• Power switch. Move the power switch to the
L1 controller within the N-brick, and to the
• 48-VDC and 12-VDC LEDs. The power switch must be in the ON (
these LEDs to be on. The 12-VDC LED illuminates green when the L1 controller is
powered on. The 48-VDC LED illuminates green when the rest of the N-brick
internal components are powered on.
• Connectors. Each connector on the left can connect to a graphics pipe via the
Ktown2 board of a G-brick. Each connector on the right can connect to an XIO
connector of an IP53 node board.
Note: The connectors that are in the same horizontal plane are connector pairs. For
example, the two bottom connectors connect to each other internally.
• Connector LEDs. Each connector has two LEDs, as follows:
– The yellow LED illuminates to indicate that both the N-brick and the brick to
which it is connected are powered on.
– The green LED illuminates when a link has been established between the
N-brick and the brick to which it is connected.
