Some idiot (one guess as to who) installed a Cisco/Linksys SRW2024P in a 2nd location and forgot to change the IP before doing so. Now it's on a new subnet and I need to control it via console port.
I'm used to controlling Cisco gear through the console port from my Mac using
screen or ZTerm and a Tripp Lite (née Keyspan) USB-to-Serial adapter, but have the benefit of being up to my neck in Cisco's blue DB9-to-RJ45 console cables. This Cisco/Linksys switch has a DB-9 male console port and I dug out a female-to-female DB9 serial cable, but I have no idea whether it's a null modem cable or not and it doesn't seem to work using the official serial port settings for the SRW2024P:
Bits per second: 38400 Data bits: 8 Parity: None Stop bits: 1 Flow control: None
I must admit that I'm usually lucky and what cables I have tend to work, but not this time. Unfortunately, the former admin ditched the box & cables. So, should I need a null modem cable like the Tripp Lite P450-006 Null Modem Gold Cable DB9F/F - 6ft or something else?
I can get all crazy if I have to, but that's a lot of effort for something I could just buy a cable for, esp. since I'd like to keep the correct cable with this switch from now on. Any other ways to get into this that I'm not thinking of?
I have tried a random serial cable and the aforementioned Tripp Lite null modem cable with my Keyspan USB-to-Serial adapter (both ZTerm and
screen), and get nothing, no matter how many times I tap enter/return (okay, I haven't tested all the possibilities there). This is with using the aforementioned serial settings as well as the following (I found both in official documentation):
Bits per second: 115200 Data bits: 8 Parity: none Stop bits: 1 Flow control: none
By connecting directly to the switch via ethernet and changing my IP to the same subnet as the original IP of the switch I can connect via the web interface, but do not have the password. And, no, it's not the default! So, my only option is serial (to perform a password reset, but that doesn't seem to be working in the slightest.
Any further suggestions would be greatly appreciated!
