Step 6 Load the switch card ﬂash memory for Slot A.

• For a Release 2 switch card in Slot A, enter the following command at the System

Monitor prompt (the 0 in sd0b is a zero):

System Monitor-> fload sa (sd0b)fware/flash_sc2.rec

If the Flash Load Fails

Step 7 If you do not see the System Monitor-> prompt, the ﬂash load has failed. Do the following:

• Disconnect from the NP by typing ‘. (backquote plus dot, that is, left single quote plus

period).

• Reset the NP as follows (the NP in slot 1 in this example):

If you see the following error message, repeat Step 6:

flash failed to erase or is not erased

ACTION_FLASH=0x45

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

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 occurs with

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

complete successfully.

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

Step 8.
