Trouble Setting Up Sun Ultra 10 - Displaying Garbage
Hello there,
I am new to this forum as well as to the UNIX world. Recently graduated with a degree in Computing and just started learning UNIX & bought 3 Sun Ultra 10 Servers. I was trying to set the Servers up so I can use them; the Servers don't have a VGA card. My laptop, which I would be using as a console, does not have a VGA/Serial out so I bought a USB to Serial cable to connect it (with the laptop and) with the Server's DB25 port (which has an adapter to convert it to RJ45). I tried the connection with a straight cable, roll over cable (RJ45 both ends) and another roll over cable (RJ45 at one end and female serial at the other); Since I have Windows 7 on my laptop hence there is no Hyper Terminal, so instead downloaded Putty Extra to communicate with the Server.
But, whenever I connect the Server(s), they either don't display anything or display garbage on screen. As I have 3 Servers, I tried it with all of them with the same result, changed the Adapters on the back of the Servers, changed my USB to Serial cable, plugged in cable into different ports of the server and etc, with same result!
Any help would be highly appreciated because I am really stuck here
Also, attaching a picture of the back of the server, as well as the cables I am using, in case I am using them with the wrong port on the server/wrong cable (though.. have tried all different combinations!).
In the Image:
1 = the port of the server I am connecting with (DB25 with an adapter to convert it to RJ45)
2 = USB to Serial cable I am using to connect my laptop to (number 5 and then to) the Server
3 = Extra Console/Roll Over cable I bought, with a female serial on one end and a RJ 45 connector on the other
4 = an extra adapter I got with the Servers (the pin settings on this are slightly different to the one(s) already in the Server (number 1)
5 = connect this adapter to my (number 2) USB to Serial cable and then have used both straight & roll over cables to connect to number 1, but the result is either empty screen or garbage on the screen.
Thanks for reading this!

sge_host_aliases
HOST_ALIASES(5) Sun Grid Engine File Formats HOST_ALIASES(5) NAME
host_aliases - Sun Grid Engine host aliases file format DESCRIPTION
All Sun Grid Engine components use a hostname resolving service provided by the communication library to identify hosts via a unique host- name. The communication library itself references standard UNIX directory services such as DNS, NIS and /etc/hosts to resolve hostnames. In rare cases these standard services cannot be setup cleanly and Sun Grid Engine communication daemons running on different hosts are unable to automatically determine a unique hostname for one or all hosts which can be used on all hosts. In such situations a Sun Grid Engine host aliases file can be used to provide the communication daemons with a private and consistent hostname resolution database. The location for the host aliases file is <sge_root>/<cell>/common/host_aliases. FORMAT
For each host a single line must be provided with a blank, comma or semicolon separated list of hostname aliases. The first alias is defined to be the unique hostname which will be used by all Sun Grid Engine components using the hostname aliasing service of the communi- cation library. SEE ALSO
