Hi netpro:

I have a sw4503, when power on ,it can't bootup normally and go into rommon mode.

i used the command "dir bootflash:"

rommon 3 >dir bootflash:

Checksum failed on yoda-fslib-m

Expected checksum: 1b4f, calculated checksum: e09d

open: file "yoda-fslib-m" not found

cannot load the monitor library "bootflash:%yoda-fslib-m" from device: Interna

l Flash Memory

dir: cannot open device "bootflash:"

rommon 4 >

I think it maybe a hardware problem,

please help to diagnose it.

Added detail:

when I uesed command "boot tftp://",

the ios can transport from pc to sw4503,

but the sw4503 always stick at loaded,no action .

Thank your help.
