2. Introduction
Thank you for purchasing PS/2 IP-KVM switch. PS/2 IP-KVM switch can save your MONEY, TIME,
SPACE, EQUIPMENT and POWER. PS/2 IP-KVM switch defines a new class of remote KVM access
devices. PS/2 IP-KVM switch combines an 8/16/32-port KVM switch with digital remote KVM access
via IP networks and comprehensive system management.
PS/2 IP-KVM switch provides convenient; remote KVM access and control via LAN or Internet. It
captures, digitizes, and compresses video signal and transmits it with keyboard and mouse signals to
and from a remote computer. PS/2 IP-KVM switch provides a non-intrusive solution for remote access
and control. Remote access and control software runs on its embedded processors only but not on
mission-critical servers, so that there is no interference with server operation or impact on network
performance.
Furthermore, PS/2 IP-KVM switch offers additional remote power management with the help of
optional available device.
PS/2 IP-KVM switch supports consoles consisting of PS/2 style keyboards and mouse, and HD 15
video output. PS/2 IP-KVM switch will automatically detect the current video mode of the console,
however manual fine-tuning is recommended to receive the best video quality. PS/2 IP-KVM switch
will accept video streams up to 110 MHz dot clock. This results in a screen resolution of 1280x1024
pixels with a frame rate of 60 Hz.
2.1 When the server is up and running
PS/2 IP-KVM switch gives you a full control over the remote server. The Management Console allows
you to access the remote server’s graphics, keyboard and mouse and to send special commands to
the server. You can also perform periodic maintenance of the server. Using the Console Redirection
Service, you are able to do the following:
I. Reboot the system.
II. Watch the boot process.
III. Boot the system from a separate partition to load the diagnostic environment.
IV. Run special diagnostic programs.
2.2 When the sever is dead
Obviously, fixing hardware defects is not possible through using a remote management device.
Nevertheless PS/2 IP-KVM switch gives the administrator valuable information about the type of a
hardware failure. Serious hardware failures can be categorized into five different categories with
different chances to happen:
I. Hard disk failure 50%
II. Power cable detached, power supply failure 28%
III. CPU, Controller, main board failure 10%
IV. CPU fan failure 8%
V. RAM failure 4%
Using PS/2 IP-KVM switch, administrators can determine which kind of serious hardware failure has
occurred (See table 2.1).
