You can try the pinouts found at
Nullmodem.com - DB-25 and
Nullmodem.com - RJ45 but you really need to find out what the pinout is as far as the NTS is concerned (you might need something just a little bit different).
Could not find any info on SUN for what is normal - the only thing I found was the following (that seemed to be of any use). Oh, you don't need to set the port for console on the E4500 side.
Console Logging Options - Tip line to ttya
This may be one of the least expensive console logging options, but can create challenges when attempting to monitor multiple systems. The system that is performing the monitoring function must be up and operational, or logging of the other systems console is lost.
To enable this console logging mode, take a standard serial cable and connect one end to the system ttya port, then connect the other end of the cable to any serial port on any other local workstation.
Once the cable is connected, a user on this monitoring system can issue the tip command and be connected to the other systems console. Note that prior to issuing the tip command, the user must enable some form of logging, i.e. Using the log to file option of an Xterm session, etc.
Using TIP
Have the system console of the 'problem' system redirected to another system.
The basic steps:
Hook a null modem cable between serial port A of the 'problem' machine and one of the serial ports of the healthy machine. The port (a or b) on the healthy machine depends on the hardwire entry in the /etc/remote file on the healthy system.
Here is the hardwire entry /etc/remote that uses port b on the healthy machine.
hardwire: :dv=/dev/term/b:br#9600:el=^C^S^Q^U^D:ie=%$
e=^D:
A null modem cable in its most basic form is an rs232 serial cable with a minimal pin connections as follows:
2 ------ 3
3 ------ 2
7 ------ 7
A standard serial cable with a null modem adapter from an electronics store will work too.
There should be an entry for hardwire already in /etc/remote. It comes with the default OS. If one is not there, you can always copy it from another Solaris system.
Now open a command-tool on the healthy system. Sometimes tip behaves better with a shell-tool, but you lose scrolling.
Type in: tip hardwire
You should see a connected message in this command-tool window.
NOTE: you will get the connected message regardless of the presence of the serial cable. Connected just means your tip session is talking to the serial port, not to another system.
