Switch IP address

[Baj]

I just started at a small company. the person that was here before didn't write down the switch ip that connect to the WAN. It was reported as having several drop packets due to a misconfiguration. The switch is a Procurve 2626. my 2 questions is this, bearing in mind that i know very little about switches:

how can i find out what the ip address is? i tried using a cisco cable connected to a laptop but it doesn't see it when i select the serial option in putty.

is it easy to change the rate from 1/2 duplex to full?

hi,

The best way is to use a serial cable to connect to the serial port of the switch.

Or you can try to do a scan IP of your network with softperfect netscan selecting "snmp" with public community string, take a llok to the quick conf guide (2-3 pages).

Regarding duplex config, under the command line :

2626(config)# interface xx speed-duplex ?
 10-half               10 Mbps, half duplex.
 100-half              100 Mbps, half duplex.
 10-full               10 Mbps, full duplex.
 100-full              100 Mbps, full duplex.
 1000-full             1000 Mbps, full duplex.
 auto                  Use Auto Negotiation for speed and duplex mode.
 auto-10               10 Mbps, use Auto Negotiation for duplex mode.
 auto-100              100 Mbps, use Auto Negotiation for duplex mode.
 auto-1000             1000 Mbps, use Auto Negotiation for duplex mode.
 auto-10-100           10 or 100 Mbps, and half or full duplex, using Auto Negotiation.

Then choose the needed configuration.

Bye.

I already connected the serial cable to the switch/laptop. I wasn't sure if it being a Cisco cable would make it not compatible. Where is the guide you mentioned located?
