I've tried several searches but didn't see any obvious answers to my following problem.
I have an rx2620. I'm attempting to use the server through a Dell-branded PS/2 KVM using a USB-to-PS/2 adapter for the keyboard and mouse.
When I power the system up, I get video and I am able to use the mouse, but I have no keyboard. I am seeing this behavior both in the EFI and after the OS (RHEL AS4 in this case) has loaded.
The adapter appears to be working as I can use both the KVM keyboard and mouse when I connect it to another non-HP server or workstation.
Any thoughts on what the problem might be?

Re: USB to PS/2 adapter and no keyboard on rx2620
Hi,
I've experienced this once not with a Dell branded, but other brand, and the result from the response center, the supported output/input devices are:
Video Monitors (Optional -- Max 1)
HP L1940 LCD 19" Flat Panel monitor
EM869AA
HP L1740 17" TFT Monitor
Pl766AA
HP L1506" 15" Flt Panel Monitor
Px848AA
Keyboard/Mouse (Optional)
USB keyboard and USB scroll mouse.
A7861C
USB Keyboard & Mouse for OpenVMS
AB552A
as a workaround I didn't use the kvm, instead I use usb mouse & keyboard. I think the problem is on the USB-to-PS/2 converter
regards,
Sandy

I never think of the future. It comes soon enough.

I've been told by a HP engineer once that even though the connection looks like standard USB it isn't 100% compatible.
When you eg unplug the mouse and plug it back in while using CDE you'll end up with a 'dead' mouse while on a PC people are used to having it work again after plugging it in.
Rebooting would resurrect the mouse again (never tried if there's another option)
That was in the time when they started with USB connections on the HP9000 workstations.
The same goes probably for the Integrity systems as well.
I've also experienced weird problems with non HP mice and keyboard on such USB connections so I'm not that surprised by the problems you have with that particular KVM device.

Re: USB to PS/2 adapter and no keyboard on rx2620
Thanks to the both of you for your replies!
After some discussion here, it appears that this may be a moot point as most users will access the system remotely. Any access needed on the physical console can be duplicated through the management processor.
