1600 LB serial access
I am not able to take the serial console of BIG IP 1600 Load balancer.. i have set the baud rate as 19200 at putty. but some junk characters appear. and sometimes end up with a blue screen of my windows.. Any body please help.
Many Thanks...
- Eric_St__JohnEmployeeIs this a brand new appliance(no previous configuration)? Are you using the serial cable that was shipped with the appliance?
- nitassEmployeehave you tried another baud rate? just in case if someone has changed it.
- Eric_St__JohnEmployeeAn RMA should not be necessary. If there was a previous configuration that is causing issues, you can create a USB bootable thumbdrive and re-image the appliance.

Hi Eric,
Yes I am using the brand new appliance. And the cable i am using is an extreme DB9 console cable. Not the one in the box.
Is it mandate to use the F5 cable for this.? and i have tried different baud rates as well.
- mohit123_63342Nimbostratusyes i have tried with other baud rates as well. its a brand new appliance.. i have 2 LB's and not able to take console of both. I guess there is something I am missing..
- Eric_St__JohnEmployeeThe cable must be a null modem cable. You should check the cable you are using, or use the cable supplied with the appliance.

- mohit123_63342Nimbostratusyes.. I am using a DB9 cable only.. I am using this appliance for the first time. As i can work with mgmt port. but some cases i need the serial console.
- El_JefeNimbostratusIf you're getting garbage characters, oftentimes, it means a baud / config issue. Make sure you configure putty for 19200, 8-N-1. As the previous poster stated, if that's not working, you need to open a support case.
- Eric_St__JohnEmployeeI suspect that the cable being used is not a null modem cable and that is the issue. Use the cable that came with the appliance.
- HamishCirrocumulusGetting chars back suggests its a comms rate problem rather than a null modem problem. No xover would tend to manifest itself as no response as you'd be listening for traffic from the recieving pins...
