Troubleshooting Flash ROM Updates

Updating Software

D-4

D.3   Troubleshooting Flash ROM Updates

Many of the problems that occur when updating the Flash ROM can be solved by 
completing the following steps:

Table D-1:   Flash ROM Troubleshooting

Protocol

Area to Check

NetWare

Ensure the file is in the login directory. Since the EPS cannot actually log into the 
file server, it has very limited access to the server directories.

TFTP

Check the file and directory permissions. 

Ensure the loadhost name and address are specified correctly and that their case 
matches that of the filenames on the host system. 

Ensure the file and pathnames are enclosed in quotes to preserve case.

Ensure that TFTP is enabled on the host; several major UNIX vendors ship their 
systems with TFTP disabled by default.

MOP

The Ethernet circuit must have the service characteristic enabled. 

Ensure that the MOM$LOAD search path includes the directory containing the 
EPS.SYS file.
