Hey all.

I'm prepping to set up an E220R server via TTY.

I haven't done this before, and want to make sure I get the right bits.

My research indicates that I can use an RJ45 cable and an RJ45-DB9
coupler to connect to a 9-pin serial port on a PC. Pointing my Windows
terminal app to the COM port should then allow me to get it going.

2 questions: 1. Should the patch cable be crossed or straight-through?
and 2. Is there a specific pinout that I should configure the coupler
for?

I've seen a page on Cisco's site for setting up cables for their
switches, but haven't found specific Sun info yet.

Thanks!

1. This depends on the coupler (or couplers, see below).
2. This depends on the RJ45 cable.

Does this E220R have a LOM card? It's a card with a RJ45 serial,
RJ12 (I think) phone line and a RJ45 ethernet connector.

If the server has a LOM card, the RJ45 serial has the same pinout
as Cisco is using. If you have a coupler and RJ45 cable that
works with the PC and a Cisco switch, it should work with the LOM
card.

If the server don't have a LOM card, I guess you intend to use a
RJ45-DB25 coupler at the server end. If you use one of those silver
couplers that sometimes is delivered with the servers, the RJ45
cable should probably be crossed (compared to what you have now
(if it was working)). Not ethernet crossed, but crossed 1<->8,
2<->7 ... 8<->1.

Well, there is no consistant standard for RJ45 to DD9 connectors.
Thus, your patch cable really depends more on how you wire up your DD9
connector.

Thankfully Sun choose to use the same exact pinout that Cisco uses,
but other manufactorers are all over the map. I think more and more
though tend to use the cisco pinout.

So, use the Cisco pinout and use a straight through patch-cord, or
a flat silver-satin type cable to connect between the two ends.

I was going to point you to the Sun docs showing the pinout, but
the hardware docs for the system at
http://sunsolve.sun.com/handbook_pub...220R/spec.html
shows that its serial ports at DB25?

A link off that page gives the RJ45 serial pinout for Sun systems that
do use RJ45 serial ports (ie, Netra X1, V100, V120, etc).

IIRC the E220R uses the same system board as the Ultra 60, which certainly
uses DB25 TTY connectors. Yep, the P/N is 501-5606 for both.

Simplest way to connect the server to a PC is with a regular RS232 modem
PC cable and a Radio Shack 9 pin null modem adapter.

_If_ the console port on your E220R is a RJ45 connector, you can use a
cisco 9pins-to-rj45 converter on your PC and the blue cisco cable
(that's a rollover 1-8, 2-7, ..., 8-1). If that doesn't work, try a
straight ethernet cable instead of the blue cable.

If you have a 25pins D-shell connector, you can use a 25pins cisco
converter plug, and try the above.

Hey all -

Turns out the port on the E220 is a 25-pin serial.

I _think_ I can get away with a standard 9-pin to 25-pin null modem
cable.

Guess I'll find out next week! ;-)

Don't forget a male/male genderchanger. Sun has the habit of using
female serial connectors on their systems, while PC's and most terminals
use male connectors.

And, if you don't need one now, you'll probably are glad you have one
when you need somewhere it in the future

I think I can handle that.

Thanks for the tip!
