IBM 2005-16B fiber switch - serial console cable

Hi,

We have an old switch installed by a supplier a while ago and that we wish to connect a new tape library we bought.
The problem is that no one knows about how the switch were configured.
I tried to connect through the console without any success.
Made the try with TIA RS-232 straight cable with DB9 connectors => I see nothing on the screen
COM port settings are as follow:
•Baud: 9600 bps
•Data bits: 8
•Parity: None
•Stop bits: 1
•Flow control: None

I also connected it with an UTP crossover cable, put a 10.77.77.76/8 IP on my NIC then tried to ping the 10.77.77.77(which is the default as stated by IBM/Brocade) but got no echo replies.
I used wireshark to snif what's happening on the line but can only see packets generated from the computer not the switch.

Could you please help?
Which serial cable/cabling is needed for that kind of switch?
is there any manner to reset the switch to its factory without access to CLI?
Is there another way I didn't try that can solve the issue?

Thank you.

Normal serial cables don't work on Brocade switches unless you cut pin 7, see http://bizsupport1.austin.hp.com/bizsupport/TechSupport/Document.jsp?prodSeriesId=352379&prodTypeId=18972&objectID=c00991261&printver=true for example.

Just press return at the password prompts to leave the default, if you change it and lose it you may never get in to configure it again. There is no reset switch unfortunately, sometimes you'd like to reset it to factory and start from scratch.

Hi andyalder,

First of all, thanks for your reply.
So i managed to get ito the console CLI with following equipment:

EQUINOX SERIAL ADAPTER
Part Code: 210120
Manufacturer: Avocent
Type: Serial adapter ( DCE ) - CAT 5
Wires per Cable: 8 wire(s)
Connector(s): 1 x RJ-45 - female
Connector(s) (Other Side): 1 x 9 pin D-Sub (DB-9) - female

Basically, it'a a DCE to UTP/CAT5 adapter. So both of serial cable termination has to be DCE wired and not DCE/DTE.
I then used a standard straight through UTP cable between the two equinox adapters and could access the CLI.

Adapters can be found here:

By the way, should this help someone:
username: root
factory password: fibranne

Grtz,
M S

That's what I wanted to make sure you didn't change.
