4/64B serial connection problem

Hi,

I am having a problem with serial connection to some SAN switches.

The Fabric has 4/64 and 4/8 B series switches. I can connect fine to the 4/8 switches RS232 serial port with the serial cable (RJ45 connector plugged into the RS232 9 PIN adapter). If I take the adapter off and try to connect to the 4/64 switches using the RJ45 serial port I don't get the login prompt.

It is the same cable, laptop, HyperTerminal and COM port settings (9800 8 N 1 N) used in both circumstances.

All switches are running the following:
Kernel: 2.4.19
Fabric OS: v5.1.1a

Any ideas?

Cheers,

Vaughan

I think you need a different cable for the 4/64B (It should have come with one) - you cannot use the old-style cable with just leaving off the RJ45/DB9 adapter.

Thanks Uwe, I suspected as much.

Our switches were provided direct by HP as part of some remedial support work they were doing, so we didn't get a box with cables etc.

I would like to order a cable but I can't find the part number anywhere. Can anyone tell me what it is or even if it can be ordered separately?
