Great! This gives you a replacement system board, too, so you
can use both serial ports (among other things).

Hmm ... does this one use a CD-ROM drive or a DVD-ROM drive? My
Ultra-60s used DVD-ROMs, as well as my earlier Ultra-2s. O.K. Looking
at the FEH -- they were supplied with CD-ROM drives, I must have swapped
in DVDs on my own -- from earlier systems. At least one of my Ultra-2s
came with a DVD ROM drive (perhaps swapped in by a previous owner) --
and I acquired others for other systems -- and kept moving them to the
newer ones until I reached systems (like the SB-1000 and SB-2000) which
came with the DVD-ROM drives as standard.
Anyway -- the DVD-ROMis a Toshiba SD-M1401, and Sun's part
numbers on them are:
390-0025
540-4683
540-4684
and if you get an older one, and want to boot from a DVD-ROM (nice when
installing Solaris 10 -- saves a *lot* of CD swapping), you'll want to
download the firmware patch and install it -- the 1009 firmware version.
(You can tell which by running probe-scsi-all before booting.)

"some sort of clip" for *what* -- and where?

Don't touch them yet.

There are -- but the side panel on the other side is permanent.
You'll need to remove the bracket which carries the CD/DVD-Rom drive
*and* the floppy -- along with a possible optional tape drive as well.
So -- to get it out (based on checking with my Ultra-60, which
is the same box, two CPUs instead of just one, and I think no other
difference other than airflow control plastic.):
1) Remove the side cover (as you have already done).
2) Look at the bezel surrounding the CD/DVD drive, the floppy (
if present), and the possible third drive) if present. You
should notice that there are a pair of grooves in the sides
about midway down.
Grip by these and yank (perhaps with someone else holding down
the box.) The bezel should come off in your hands. (I didn't
have easy access, so I had to place something in the groove on
the right as viewed from the front and hit that with the heel of
my hand, then hold that forward as I worked the other side
clear.
3) Look into the cavity -- just below the DVD-ROM drive. You
should see two captive slotted head screws. Loosen these until
they pop out (I think that they are spring assisted, and will
come out about 1/4" or so before stopping.
4) Start to pull the entire cage forward -- drives, cables, and
all.
5) Stop and spend some time unplugging ribbon cables and power
cables from the drives.
6) You can now slide the drive cage all the way out, and can
now access the screws from both sides, allowing removing
the drive from the cage. (But -- if you have the same drives in
both systems -- why not pull the entire cage from both, and
exchange them?) It will be easier and you can probably
disconnect the cables at the system board end instead of at the
drives.

The only two ways that I know of getting that side open are a
pneumatic nibbler after drilling a hole in the side to start it, or a
cutting torch (either of which will do nasty things to the "skin" over
the metal chassis -- and probably to many other things in the system. :-)
It is not *made* to come open. Instead -- the drive carrier is
made to pull out the front.

And removing your old drive.

I have a question -- does the drive "eject" before you start to
boot, or only when booted? I remember having problems with one which
ejected volutarily when booted.
Also -- check whether "vold" is running. If it is
ps -ae | grep 'vold'
then try:
sh /etc/init.d/volmgt stop
to turn it off temporarily. You might not need to swap out the drive.
I've already told you how to turn it off permanently, along with other
things controlled from /etc/init.d.
Also -- check that the SCSI cable is connected *firmly* at both
ends. If it is not, it could be sending confusing signals to the drive,
causing it to eject.
Good Luck,
DoN.
