5.7 Software Download Procedures
There are three different methods for upgrading host firmware in the field. They include a
CPU swap, XMODEM binary file download, and TFTP or TFTPD protocol binary file
download. Each is detailed in the following sections.
5.7.1 CPU Swap
The first and easiest way to accomplish a field upgrade is to order an upgraded CPU from the
manufacturer and swap the CPUs at the CPE site. Following are instructions for swapping the
CPU cards.
1. Loosen the screws from the top and bottom front panel on the existing CPU, and remove
the card from the chassis.
2. Unpack the upgraded CPU and slide into the same slot in which the previous CPU resided
(usually the C1 chassis slot).
Following the CPU swap, the system re-initializes. Upon completion of re-initialization,
verify that all circuits are active and operating.
