download update-file
The update file is transferred to the switch asynchronously from either an INADS
host or a personal computer (PC) using the XMODEM protocol.
Remote download
Remote users can dial into the switch by either using the “call” command (from
an INADS host) or by dialing the switch directly with a modem. Once the
connection has been established, the user logs into the switch as a remote
system access terminal (SAT) using the inads login.
NOTE:
Only the INADS and INIT logins have the necessary permission to send an
update file to the switch.
1. Type the
download update-file
command and press
ENTER.
“Please
wait..."
displays on the screen.
After completing some initialization,
"Please start file
transmission now..."
displays.
2. Start an XMODEM session on the remote end and send the update file.
a. INADS host: enter
~dload <
file_name
>
to start the file
transmission.
b. PC: follow the instructions in the emulator’s manual for invoking an
XMODEM session to send the update file.
Each block is written to tape or flash card as it is received by the switch. The link
level of XMODEM provide error detection and retransmission. Additional
protection is provided within the application level. After the entire file has been
written to tape or flash card, it is read back and each update file block is
validated, and the file checksum is also checked. If the file appears to be sound,
the status word in the header block is changed to indicate that it is a valid update
file.
There may be a delay between the end of the file transmission and command
completion. This delay is caused by the patch application of any immediate
sub-patches.
