7. Insert the new boot EPROMs.
Insert the new boot EPROMs one at a time, using as a reference the location
number and the relevant location diagram. Check that the boot EPROMs
are firmly seated.
Install the boot EPROMs the correct way up! Failure to do so will almost certainly
destroy them. The 'top' end of the EPROM has a notch. This should be positioned so that
the notched end of the EPROM is orientated as shown in the relevant location diagram.
8. Replace any MAC card (AR300 Series only).
Replace any MAC card removed in step 5. See "Installing a MAC" on
page 83 for instructions.
9. Replace the router lid and the power cord.
Replace the router lid and secure it with the four posidrive screws. Connect
the power cord, and switch the router ON.
10. Check that the router is operating correctly.
Check that the router boots up correctly. See "Router Start-up" on page 10
for a list of start-up messages. Verify that the new software version is
installed by typing the command:
SHOW INSTALL

boot EPROM software release number is shown in the "Default" field.
Check that this is correct.
