Unable to console with 2524

[G_40]

I have a new 2524 Switch, when i want to connect on console mode i have no response from the switch (white screen with HyperTerminal).
If i reset the switch with HyperTerminal opened, i have strange characters on HyperTerm window.

HyprTerminal's configuration is ok (2400 - 8N1, Hardware Control). The com port is good.

I test to reverse swith in Factory Default configuration but I have always the same problem.

Anyone know how resolv this problem? I can't managed my swotch by telnet because it haven't Ip for the moment, I have to connect whith console first to configure IP ;(

Thanx, Pluger.

have you checked your cables? i have had some switches and hubs that required null modem adapters to make them work. are you using the cables that came with the unit?

Try setting your com ports configuration to 9600 baud instead of 2400.

HyperTerminal is not always the most ideal terminal emulator. There are some good freeware tools available.

A normal config for Hyperterminal to connect to the switch:

9600-8N1 Flow Control=None

If you have connection to the switch it's wise to fix the console setting to:

2524(config)# console baud-rate 9600

Hopefully it works.

9600-8N1 Flow Control=None

This is the correct setting though I have sometimes connected at higher Baud rates which solves the problem you are having. Flow control must be none

Hi. I suggest
you can use modem to connect and config.
on the other hand, if console port is wrong, you have no modem.
you can use DHCP and make 2524 get ip address, and by toptools in network check ip address, and then you can telnet, web mode config.

Hi.

Once more, com port settings:

9600
8 databits
no parity
1 stop bit
no flow control

But, I'd suggest you check out Tera Term Pro;

Freeware console/telnet client, which works.

Hi,

I have a similar problem.

I know it's not the terminal program that is the problem, or the cable I am using, as we have 15 of the same model switch and *some* of them respond to serial console, whereas others do not.

Have you been able to find a workaround? I have tried a few different ways to access the switch, but am unable to.

Regards,

Nige.

Hi.

"*some* of them respond to serial console, whereas others do not."

... which is precisely the probelm with Hyperterminal. Check out TTPro.

HTH,

Try using Xon/Xoff...

[Gonzo Granello]

This is a chronical, know problem with almost all ProCurve switches. HP just needs to fix it. In the meantime the only real solution is to pull the power....

@ Gonzo,

I would not say that this is a problem with all Procurve switches I have only seen it on the 2300 and 2500 series frequently and on the 4100 series sporadicly.

The problem is more likely to be Hyperterminal, because when I switch to TeraTermPro I have no problems whatsoever contacting the switches over the consoleport. And of course using the correct settings.

I agree with Scooter. I have seen the same with Nortel switches. Generally, I only console to the switch during initial setup and have always made is standard operating proceedure to spark up Hyperterm before powering up the switch. Once the switch is in service, I seldom if ever find a need to Hyperterm to it.
