The labels on the rear of the NV8576 and NV8576-Plus frames reflect this numbering. How-
ever, slots are ordered differently with respect to port numbering.
Slot Order for Port Numbering
Port numbers increase with consecutive slots in the ordering for port numbers.
NV8140, NV8144 or NV820
Port numbering for the NV8140, NV8144, and the NV8280 follows the physical slot numbers.
NV8576
Slot ordering (for ports) for the NV8576 follows the ordering
1
shown in figures 2-5 and 2-6. An
NV8576 has 64 output slots (32 upper and 32 lower) and 64 input slots (32 upper and 32 lower).
This is the ordering of slots for input port numbering, as viewed from the rear:
