How do you setup and configure hp 513735-001 kvm switch in a datacentre environment with eight server?

SOURCE: Manual for the Protec Bytelan KVM/4

The switches are used when cascading more than a single BYTELAN KVM. It specifies the scan rate, and which KVM unit the keyboard and mouse are connected to. For a single KVM, use the default settings. SW1 SW2 Scan Rate ---------------------- ON ON 2 seconds OFF ON 10 seconds ON OFF 20 seconds OFF OFF 40 seconds SW3 NOT USED SW4 ON For KVM unit with KB/mouse OFF For other KVM units w/o KB/mouse, If your power supply isn't adequate, it may cause your KB/mouse problem. It should be 9VDC with at least 500ma. Hope this helps.

Ok so this is not a hub, but in my experience with similar setups, it comes down to a handful of possibilities.

1. As with djnick's suggestion, older cables can give problems and if the ports are in an area where they may attract dust, or be poorly groomed ( meaning cables are dangled or twisted and crossed, may also be under excess strain )
   
2. Excess heat or moisture - check around the area, place a thermometer near the unit and check this against safe operating temps and humidity ratings ( should be on the unit or at least in the handbook)
3. Get some pen and paper and make a note of how the setup is currently setup so as to avoid confusion when re-connecting the cables.
4. Take particular note of the ports not shown or responding, and test each one in turn with a lead that is known to work, this will only eliminate bad leads, not bad ports.
5. Try using the leads from bad ports in good ports, this can also help eliminate the good eggs from the bad ones.
6. The only other way is with to blast the ports with a can of compressed air ( not available in all countries due to safety concerns with the product ) - may have to resort to another method, but do take care and as with most units of this nature try to avoid using suction on the ports or internal components.

• Worst case scenario you end up back at square one and the problem remains. This could also mean the problem lies with the software that is running, or any firewalls in the network may also be blocking the ports & may need a rule created to allow these ports to work.
• Consider every option carefully as sometimes the solution may be closer then you think.

This happened to me until I installed the activeX control. Were you prompted for that, and did it install successfully?

After the activeX installed, did it also prompt you to install the secure certificate to access the site without IE prompting about invalid certificates?

Since you've tried multiple machines, I doubt security settings on IE are causing the problem. But my switch did these two actions before I was able to login successfully.

I've had that happen when I've added some newer rev SIPs. The newer ones come with a notice to load the 2161DS with versions 2.0.13 or newer firmware; by unplugging the new SIPs and leaving just the older ones (and I'm at a loss as to the exact revisions) I got back the OSCAR prompts. Plug the SIPs back in one at a time, and they would display, but once the session timed out, the key sequence would do nothing once again. Don't know if this is what you have, but I do know that certain SIPs can interact with your firmware to cause this symptom - my bigger problem now, is that when I try to update with the newer firmware (d2_0_13_english.fl) I get a message: "Unable to upgrade the firmware. Reason: Incompatible file."

Please make sure that the keyboard is hooked up on the KB port of the KVM. check underneath the GCS632U for the correct console port. you will see a keyboard and mouse icon. Make sure that the keyboard is connected to the keyboard port. tap scroll lock key twice to switch between computers.
