In order to run the RSC as before after changing the System Board it is
necessarry

  I)   to restore the configuration into the appropriate chip at the
       new board (the RSC Flash PROM is on the E250 System Board at U4401)

and, if the NVRAM is also changed, 

  II)  to perform an update for the RSC-MAC-Address
  III) to set some NVRAM Parameters.

Detailed description of the three steps
=======================================

I)
  
Although there is a backup file mentioned [1,Chapter 7] it is not possible
to store and restore the RSC Configuration by a file yet. The way to restore
the configuration is to log them manually by the command rscadm [3] and
configure the new RSC Flash PROM on the new System Board using rsc-config [3].
It is recommended to backup the RSC Configuration in order to avoid problems 
when the System Board is broken.

Example RSC Configuration:

	/usr/platform/sun4u/sbin/rscadm show

page_enabled="false"
mail_enabled="false"
ip_mode="config"
ppp_enabled="false"
serial_hw_handshake="false"
tpe_link_test="true"
serial_baud="9600"
serial_parity="none"
serial_stop="1"
serial_data="8"
customerinfo=""
ip_addr="10.0.0.100"
ip_netmask="255.255.255.0"
ip_gateway="10.0.0.200"
mailhost=""
mailuser=""
page_info1=""
page_init1=""
page_password1=""
page_parity1="even"
page_stop1="1"
page_data1="7"
page_baud1="300"
page_info2=""
page_init2=""
page_password2=""
page_parity2="even"
page_stop2="1"
page_data2="7"
page_baud2="300"
ppp_local_ip_addr="0.0.0.0"
ppp_remote_ip_addr="0.0.0.0"
hostname="lab-rsc"
escape_char="~"


After changing the System Board it is neccessary to perform

	/usr/platform/sun4u/sbin/rsc-config

and enter the values when being prompted.


II)

The RSC-MAC-Address is related to the systems MAC-Address and must be updated
with the following command in the OPB:

	rsc-mac-update

For more detailed information see [1], [2].

III)

To redirect all in- and outputs to the RSC the following NVRAM Parameters
must be set with the proper values:

	setenv output-device	rsc
	setenv input-device	rsc

and the following command in the OBP must be performed:

	diag-output-to	rsc

For more detailed information see [1], [2], [3].
