Over the next ten days or so, I'll be dumping several bits of old
network equipment in the skip at work, and thought I'd see if anyone
here might want any of it. Before you get too excited, some of it
"needs attention", ie is faulty :-)
Firstly, there's a pile (20 or so) of Emulex Performance 4000 32-port
terminal servers. Not sure exactly which model, but I know that all
the ones I have boot over the network (we used DECnet but BOOTP/TFTP
should work just as well if set it up properly). You can get firmware
and other stuff from Emulex's FTP site (I just checked).
Each has 32 MMJ serial ports, a 10base2 BNC, 10base5 AUI, and possibly
a parallel printer port. I can provide a bundle of short MMJ-to-RJ45
cables for each, if required. Unfortunately almost all are "dead".
The common fault is a blown power supply -- they used to die regularly
-- and probably not hard to fix if you have relevant
experience/knowledge. The power supply is a 3-rail 60W circuit board,
not unlike an industry-standard 3" x 5" unit, but slightly larger, so
you might be able to persuade a standard unit to fit (spec is 5V _at_ 6A,
+12V _at_ 1.5A, -12V @ 1.0A).
The other pile I'm chucking contains a quantity of 10baseT 3Com FMS II
hubs, some with management units, some without. Most are 24-port but
some are 12-port. There should also be some 3Com PS II 40 hubs, all of
which have on-board management, and all of which are 24-port. All are
19"-rack-mountable, and have a serial port (except the ones without
management). The FMS units can accept one transceiver module in the
back; the PS II 40s can accept two, and we have some spare modules (not
sure what, but probably a few 10base5 AUI ports, one or two 10base2
with BNC connector, and some FOTs (10baseFX Fibre Optic Transceivers
with ST connectors). The older ones aren't very exciting as hubs but
are a useful source of Astec 40W (no, not 60W) 3-rail 3"x5" PSUs.
Lastly, I have an HP LaserJet 5M printer with optional 500-sheet Tray 3
and a 10base2/10baseT/Appletalk network interface, in good condition.
This is the only item I want a monetary contribution for: make me a
(small) offer.
These are PICK UP ONLY -- I haven't time or resource to ship things --
and must go within 10 days. They're "free to a good home" but without
any manuals (unless you're extremely lucky) and with absolutely no
warranty or even guarantee of electrical safety. If you want some of
this stuff, please contact me off-list.
