OFF indicates that the PHY did not find a valid link on the net-
work connection. Transmit and receive operation are not pos-
sible.
In this situation the hardware is performing Autonegotiation
without any software interaction.
”Receive Activity” ON indicates that a packet is being received in 10BASE–T or
100BASE–TX mode.
”Transmit Activity” ON indicates that a packet is being transmitted in 10BASE–T
or 100BASE–TX mode.
2. 9. Operational Settings
2. 9. 1. NVRAM Setting
The NVRAM contains a set of parameters which are used by the software. After power
up, the monitor checks the parameter called magic.. If magic. is anything else than
RISCPROM, e.g. if a new and empty NVRAM has just been inserted, the monitor does the
whole set of diagnostic tests and sets the NVRAM parameters to the following default
values:
netaddr=0x149.236.99.99
netmask=0xffffff00
lbaut=9600
rbaut=9600
bootfile=bfs()/usr/diskless/clients/spect/root/unix
bootmode=c
console=0
cpuid=0
resetpc=xxxxxxxx
resetra=xxxxxxxx
eth_addr_ch1=0x
eth_addr_ch2=0x
version=5.40
magic=RISCPROM
model=CCU R4600
vendor=BRUKER
rootname=0
use_bootparams=1
keyswtch=0
keyboard=AT
This procedure takes a few minutes. The monitor prints a test protocol and at last its
prompt (
>>) on tty0 which is the default console output.
The NVRAM parameters can be printed with the monitor by
printenv
and can be changed by
setenv
parameter
value
A problem crops up if magic is equal to RISCPROM and lbaud and rbaud doesn’t meet
the bauderate of the connected terminal or
console doesn’t meet the interface to which
the terminal is connected to. Then no printout or input is possible. To correct this
