Slot Numbering
The PA-POS-20C3 is supported on a FlexWAN or Enhanced FlexWAN module used in the Cisco 7603
router, Cisco 7606 router, Cisco 7609 router, or Cisco 7613 router. The FlexWAN module can be
installed in any slot of a Cisco 7600 series router except slot 1, which is reserved for the supervisor
engine. Port adapters can be installed into either port adapter bay 0 or port adapter bay 1 on the FlexWAN
module.
Cisco 7603 routers have two slots for port adapters. The slots are numbered from top to bottom. You can
place the port adapters in either of the FlexWAN module slots (slots 2 or 3). Slot 1 is always reserved
for the supervisor engine.
