Rear Slot Numbering for Half-Height Line Cards
Rear-installed line cards must be installed directly behind their respective front-loaded application card. For example, an
application card in Slot 1 must have a corresponding line card in Slot 17. The redundant line card for this configuration
would be placed in Slot 33. This establishes a directly mapped communication path through the chassis midplane
between the application and line cards.
To help identify which rear slot corresponds with the front-loaded application card, note that the upper rear slot numbers
are equal to the slot number of the front-loaded card plus 16. For example, to insert a line card to support an application
card installed in slot 1, add 16 to the slot number of the front-loaded application card (Slot 1 + 16 slots = Slot 17). Slot
17 is the upper right-most slot on the rear of the chassis, directly behind Slot 1.
For lower rear slot numbers, add 32. Again, a redundant line card for an application card in Slot 1 would be (Slot 1 + 32
= Slot 33). Slot 33 is the lower right-most slot on the rear of the chassis, also behind Slot 1.
