System Monitor->

Reboot NP

Step 9 To load operational software into the NP, reboot it as follows:

System Monitor-> reset

Verify Flash Version on All Upgraded Switch Cards

Step 10 Log in on the NP as root.

Step 11 To see the current ﬂash checksums of Switch Card A, enter the following command:

bash# sysver -s sa -all

To see the current ﬂash checksums of Switch Card B, enter the following command:

bash# sysver -s sb -all

If the ﬂash checksum is 0x64A2 for a Release 2 switch card or 0x5D00 for a Release 1

switch card, the speciﬁed switch card now has the latest ﬂash image.

If you see the following error message, repeat Step 8:

flash failed to erase or is not erased

ACTION_FLASH=0x45

If you do not see this message and do not see the System Monitor-> prompt, go back to Step 7

followed by Step 4 and Step 5 (as speciﬁed in Step 7). After performing Step 5, resume the present

procedure at Step 9.

If you see the following error message when loading a Release 1 switch card, reboot the primary

NP:

Flash failure occurred when setting DONE bit.. (timeout)

Then perform Step 2 to verify that the checksum is 0x5D00. This problem only happens with

redundant Release 1 switch cards. The message is misleading, because the ﬂash update does

complete successfully.

If you see the System Monitor-> prompt, the ﬂash load has completed successfully. Go to Step 9.
