NV8288-Plus
Figure 2-6 on page 10 shows the front of the NV8288-Plus with the door removed. From this view,
in the slots that do not have an active card installed, the backside of installed backplanes and the
motherboard connectors are visible. The router features 36 upper bay slots and 36 lower bay slots
for input cards and output cards. In the upper bay are two additional slots for two control cards. In
the lower bay are two additional slots for one monitor cardset (composed of two monitor cards).
Slots have colored guides that match the color of the ejector lever on the card that is installed in that
slot. For more information, see
Active Cards on page 15.
Located in the center of the router are two horizontal slots housing two crosspoint cards. At the top
and bottom of the router frame are two removable fan trays.
Inputs are numbered 1–288 with each card slot, and the card it holds, corresponding to 12 input
connections. This means that input slot 1 corresponds to inputs 1–12, input slot 2 corresponds to
inputs 13–24, and so on, up to 288.
Outputs are numbered 1–288 also, but each card slot contains two types of output connections: 6
connections for outgoing signals for the local router and one expansion connection for outputs to a
connected NV8288-Plus router. This means that output slot 1 corresponds to outputs 1–6, output
slot 2 corresponds to outputs 7–12, and so on, up to 288.
