presented in Chapter 1.
2 Disconnect any cables, if necessary.
3 Remove the DPE module from the chassis.
a Loosen the two captive screws with the flathead screwdriver.
b Press outward firmly and evenly on the ejector tabs.
The DPE module will eject from the slot.

When you replace the DPE module, the firmware parameters that were
previously configured by the SysconF command in the software are not
automatically updated to the FPROM of the replacement DPE module. You must
reconfigure these parameters. Refer to the software guide for configuration
information.
