When NVRAM is selected, the Model 281xSA hub configures
itself during power-on or reset using the parameter values obtained
from the NVRAM (if they exist).
p
[Toggle boot protocol] Shifts the boot protocol among Auto, IP,
IPX, and IP_IPX. The factory default setting is Auto.
When Auto is selected, the Model 281xSA hub tries to find its IP
or IPX configuration parameters over the network. This process
has two stages:
■
First the Model 281xSA hub seeks the IP parameters and
configuration file from a BootP server, transfers the
configuration file, and writes the values (if it finds them) into
NVRAM. (Without IP parameters stored in NVRAM, this
Model 281xSA hub cannot be managed by IP.)
■
Then the Model 281xSA hub seeks the IPX parameters and
configuration file from a Novell server and writes the values
into NVRAM.
As long as it can find either IP or IPX parameters, the Model
281xSA hub writes the values into NVRAM. If the Model 281xSA
hub fails to locate either an IP BootP server or a Novell (IPX)
server or router, it resets and starts over.
When IP is selected, the Model 281xSA hub tries to locate a BootP
server and load the IP parameter values. It also writes these values
into NVRAM. If it cannot find a BootP server or transfer the
configuration file, it times out and returns to the Boot main
menu without obtaining a network address. If IP is selected, the
Model 281xSA hub does not look for IPX parameters.
NOTE:
When NVRAM is selected as the boot mode, you must use
the menu selections to set or change the required parameters.
NOTE:
If m [Toggle boot mode] is set to NVRAM, this parameter
is ignored.
