Explanation:
Enter the LOAD START command to download new firmware. During the download process, feedback
consisting of an increasing page count appears every second on the terminal screen (Example 5-19).
Each page represents one loaded 128 byte flash page; there are two cyclic redundancy checks (CRCs)at
the end of the load procedure. For a successful load, the CRC will match the Cisco-provided CRC (Cisco
provides the CRC with its firmware upgrade).
If during download the rate of updates halts and no CRC is displayed within 10 seconds of the halt, the
download has failed.
Note In the figure below at the “0 pages loaded line” , CR/LF (carriage return/line feed) pairs have been
substituted for LFs to enhance readability. The actual download procedure only uses LFs.

Use Table 5-13 to interpret the LOAD START command results.
A LOAD ABORT command reverts an EDFA that is waiting for a firmware upload to normal mode.
Any firmware file sent to the EDFA is rejected. You must reissue the LOAD START command for the
EDFA to take action on a firmware file (Example 5-19).
Example 5-20 LOAD ABORT Command
0-0>LOAD ABORT
Aborted
0-0>
Note The LOAD REPORT command is used only for diagnostic purposes.
