Note – If you answered no to the question on halting the system, the installation
will continue but the updated firmware will not become effective until the next
system reboot. The NVRAM configuration variables are changed to default values at
the next system reboot. If you customized NVRAM configuration variables you must
change the values back to their customized settings.
9. Turn the keyswitch to the Standby position.
10. Turn the power on to the system. As the system boots, diagnostics will be run at
boot up because the OpenBoot
diag-switch?
was set to
true
in the flash
PROM update procedure. Running diagnostics could take several minutes.
Note –
Other NVRAM variables may be reset to their default values, which could
affect the system in other ways. For example, if you ran the flash PROM update
through the serial port and the system still has its keyboard plugged in, you will no
longer get any response from the serial port connection. The firmware will be
waiting for input from the keyboard.
TABLE 5-4
, which follows, describes the
workarounds for NVRAM settings.

sequence by pressing the Control and ] keys simultaneously. This returns you
to the telnet command line. Type
send brk
at the telnet command line.
d. If you are connected to serial port A via a tip connection, send a Break
sequence by typing the characters ~# in quick succession.
