Just need someone to tell me if I'm right or wrong with these 4 thoughts...
(If I'm wrong, I'm sure you'll enjoy letting me know! :-)
Here's what I have...
7 Cabletron 12 port 10baseT hubs
- 2 - MRXI 93 Series
- 2 - MRX 93 Series
- 3 - MRX
They all have female AUI in media port 13, and media port 14 is blank.
For the console port (RJ45) on the MRXI, it says you can use VT200 or 300
terminal. So, in digging around...
and here http://csgrad.cs.vt.edu/~tjohnson/pinouts/#communications
... to wire up a VT420, I need to make a cable wired like this...
Console port ----- VT420 port
Tx 1 ----- 5 Rx +
Rx 4 ----- 2 Tx +
Ground 5 ----- 3 Tx -
|--- 4 Rx -
DSR 2 ----- 1 DTR
DTR 6 ----- 6 DSR
And, to connect them all together, I believe I have 2 choices...
1 - Connect port 12 on one to port 11 on another, via a RJ45 crossover cable
- or -
2 - Connect the port 13 AUI to a DEC Delni
--- Now, if I had a male AUI (or a male-male AUI cable), I could connect two
of them directly that way, right? Something tells me no on this one, but I
asked anyway :-)
Next, the two MRXI support SNMP management. Is there a good
freeware/shareware/something program for managing these? I have Digital
ServerWORKS/ManageWORKS v.3.2 (and v.2.2B), that says it supports any SNMP
device. That would be fine, right?
Does anyone have any software or hardware available for these hubs?
