    Hi,

    My client recently purchased a AP5201 KVM and (6) LCD/KVM USB Cable (AP5821).

    The issue is that the connected servers doesn't respond to console keyboard & mouse. However, they can switch server screens using hotkeys, which means the connected keyboard is functioning. But when they try to logon at the server's screen, the server just doesn't respond to keystrokes and mouse pointer remains idle.

    Is it because AP5201's console comes with PS/2 Keyboard & Mouse Interface ? But if APC offers KVM USB Cable (AP5821), there shouldn't be a compatibility issue, right ?

    My first thought is to check whether legacy USB (1.1 or 2.0) is enabled on the server (BIOS and/or OS). AP5821 I think only supports USB 1.1 and I think also USB 2.0 for keyboard/mouse. 

    I don't think this has anything to do with the console input being VGA & PS/2 just yet based on the fact you said the KVM On Screen Display menu is working OK.

    Hi Angela,

    After a long queue, We've finally got the chance to reboot and change BIOS settings. There ain't options for USB 1.1, at most backward to USB 2.0. However, server is still not responding to the KVM. We've also plugged in a desktop PC into another KVM port and to my surprise it is also facing the same problems, not responding to keystrokes or mouse.

    Anymore suggestions ? I hope it doesn't just supports USB 1.1.

    So to confirm, you have a PS/2 keyboard and mouse connected to the console port (to control and navigate the KVM menus) with NO adapters converting a USB keyboard and mouse to PS/2? Then, the AP5821 is connected between your server (and desktop PC) and AP5201, with green end into KVM and blue VGA/USB to server and desktop PC? (Sometimes, cables have accidentally gotten connected backwards and "sort of" work.

    I tend to think everything is connected OK since the KVM on screen display is OK but just want to check.

    I will see if my colleague can test this. I was thinking this AP5821 cable worked OK but maybe it doesn't. I'll report back shortly.

    In general though, I will see what we are doing with these KVMs and USB 3.0. This model is older so I am wondering if it only supports USB 1.1. I don't want to speculate though but I will start a discussion about compatibility/operation with USB 3.0 on KVM.

    Hi again,

    Well, I stand corrected. I had my colleague try AP5821 with one of these KVMs and it did not work - received the same results as you, regardless of BIOS setting. frown

    We are trying to find one of the AP52XX USB cables for testing. Do you have any of these (part # AP5253, AP5257, or AP5261) that are mentioned here as compatible in the user's guide: http://www.apc.com/salestools/ASTE-6Z5QBL/ASTE-6Z5QBL_R2_EN.pdf 

    These are the original USB cables designed for use with this KVM and attached servers and are just varying lengths. If one of these still does not work, then we maybe we have a USB compatibility issue. But, we should confirm one of these successfully works before assuming there is a problem based on both your testing and our testing with AP5821 (which also isn't listed as supported).

    Hi Angela,

    I was hoping it was just a case of wrong or backward connection. unfortunately not. I've spent quite a bit of time on the installation manual especially page-6 (KVM Rear View) to make sure all cables are plugged in correctly. The keyboard & mouse are pure PS/2 with no converters. The Hot Key works, so that should be a strong indication that at least the PS/2 Keyboard is in good working condition.

    AP582x type cables are listed as one of the first options in the AP5201 product overview page. However in the user manual only AP52xx type cables are listed. Utmost confusing !!

    I hope it's not compatablity issue between AP5201 and AP582x cables.
