NV8144
Figure 1-4 shows the front of the NV8144 (with the door removed). At the top of the frame is the
fan tray. Directly below the fan tray are card slots. On the far left are 8 output card slots. Directly
to the right of the output cards is a single slot for the monitor card. Near the center of the frame,
to the right of the output cards, are 2 crosspoint card slots. The first slot holds the primary cross-
point card. The second slot holds a second, optional 144×144 crosspoint card for redundancy.
To the right of the crosspoint card slots are 16 input card slots. To the right of the input card slots
are 2 additional slots for the primary and secondary control cards. Below the card slots, at the
bottom of the frame, are 2 bays for PS8100 power supply modules.
