Key
PMC rear I/O signals (see the
section)
Alternative PMC I/O (note that PMC I/O [45:48] are no longer available)
Ethernet channel 0 (10/100BaseT)
Ethernet channel 1 (10/100BaseT) or Ethernet channel 0 (10/100/1000BaseT)
General purpose I/O (4 bits)
COM1 (RS232)
COM2 (RS232/RS422)
USB2.0 Port 1
USB2.0 Port 2
CAUTION
If an IMP2B is configured for Gigabit Ethernet and is connected to another Gigabit Ethernet capable
device, the CPCI3UX605 (if used) must be configured to allow the port to be fully connected. Failure to
do so will prevent the Ethernet port from functioning correctly.
