Updating Software Reloading MSS Software
E - 3
• The MSS.SYS download file should be world-readable on the host, regardless
of which download protocol is used.
• Use the Show Server Bootparams command to check the MSS settings and
verify that the correct download file has been configured before using the
Initialize Reload
command to reboot the server and reload the code.
NOTE: It is very important to check the MSS settings before using the Initialize Reload
command; this ensures you are reloading the correct software file.
The reloading sequence is as follows:
1. If BOOTP or RARP is enabled, the MSS will request assistance from a BOOTP or
RARP server before starting the download attempts. The MSS will then try
TFTP, NetWare, and MOP booting, in that order, provided that it has enough
information to try each download method.
2. The MSS will download and rewrite the Flash ROM. This step will take approx-
imately two minutes from the time the Initialize command is issued.
3. If the download file cannot be found or accessed, the MSS can be rebooted with
the code still in Flash ROM. As noted in Chapter 2, the OK LED will blink
quickly while the MSS is booting and reading code, and then slowly when it
returns to normal operation.
NOTE: If you experience problems reloading Flash ROM, refer to Troubleshooting Flash
ROM Updates on page E-4.
E.2.1 NetWare
The MSS.SYS file should be placed in the login directory on the NetWare file server. The MSS
cannot actually log into the file server; it knows no username or password. It can only access files
in the login directory itself. On the MSS, become the privileged user and specify the fileserver
name, filename, and path.

E.2.2 TCP/IP
Downloading involves the Trivial File Transfer Protocol (TFTP), and optionally BOOTP. The MSS
will make a BOOTP query each time it boots. If a host provides BOOTP support, it can be used to
set the MSS’s IP address and loadhost information. Add the MSS’s name, IP address, hardware
address, download path, and loadfile name to the BOOTP file (usually /usr/etc/bootptab). The
path and filename are case sensitive; they must be enclosed in quotation marks (““).
