E2T or RTC Processor

Tip: Refer to the 3300 ICP Engineering Guidelines to determine when a
second processor is necessary in the MXe.
Tip: The MXe Server ships with both E2T and RTC as standard equipment.
CAUTION: If you are replacing an RTC in an MXe or MXe
Server running 8.0+ software, you may need to change the
