3Com SuperStackII Router

By jason3k ·
I have an older SuperStackNETBuilderII model 462 router with 2 ethernet ports and and a T1 port. My boss would like to use it as a router between 2 subnets to segment the network traffic. My problem is that I can't seem to get the ethernet ports tocome up. I believe I have them configured correctly, but will not connect when I plug in a cable. I thought perhaps it needed a crossover cable, but no dice.

What am I doing wrong?

3Com SuperStackII Router

Possible problems:

- Crossover vs. straight-through cables (as you identified)
- 10Mb vs. 100Mb ports
- full duplex vs. half-duplex

I would figure that 3COMs are capable enough of auto-sensing but it may be that they were specifically configured a particular way for some reason (autosensing can cause problems in some setups).

If you can get a console cable, get into the box via a serial link and change the port settings to combinations of the above to get a link. Note that you can'trun full duplex to a hub. If I remember correctly, 3COM had some weird thing where they decided not to use the same straight-through console cable either, so you may have to use a crossover-console cable (basically swap pins 2 and 3 on one side of the console cable).

Hope that helps -
