Hardware

Ethernet

• One 10/100BaseT connection
• Standard RJ-45 connector
• LEDs for link, 10/100 indicator, and network activity
• DDC2B compatible

VGA input

• Max resolution 1280 x 1024 at 75Hz
• Supports all VESA graphics modes, and text modes
• DDC2B compatible

VGA local output

• Copy of input video with OSD (On-Screen Display) for setup
• Optional use, when no screen is present locally

PS/2 Keyboard / Mouse

• Emulates standard PS/2 keyboard and 3-button PS/2 mouse
• Connects directly to server
• Keep-alive feature means server is not affected by power failure on the Kaveman ( it keeps emulating the mouse/keyboard even if the main power to Kaveman is removed )

Local PS/2 Keyboard / Mouse

• Allows local access to the controlled server
• Can be disabled or password protected to limit access
• Used for initial setup of network address, subnet mask, etc.
• Optional once system is deployed
• May be connected/removed without affecting the controlled server

Serial Port 1 (RS-232)

• Standard baud rates up to 115,200 bps
• Can be used for multiple functions:
  • Telnet access (console server mode) - Handy if connected to serial port of Unix machines
  • Watchdog mode - With appropriate server software, the Kaveman will function as an external watchdog which will kill the power to reset failed software/hardware
  • Power control - When connected to a Kaveman power control strip, the serial port may be used to control the power to multiple computers
  • Log monitor - Watches for regular expression string sent from the computer to indicate trouble

Serial Port 2 ( RS-232)

• Can be directly connected to a Kaveman Power Control Strip
• Same features as Serial Port 1
• May be used as second serial port with optional adapter cable

Reset

• Hardware reset button

Power

• 100-240 VAC @ 50/60 Hz, auto - sensing
• Built-in industrial strength power supply with detachable standard IEC 320 connector power cord

Mechanical

• 1 rack unit wide (1U) .
• Dimensions: 17" W x 3.5" H ( 1U ) x 11.25" D
• Aluminum sheet metal construction, painted

Internals

• Contains hardware random number generator
• Flash-memory based firmware may be field-upgraded over the web interface
• Dedicated 32-bit micro-processor

Software

Network Protocols

• HTTP/1.1 and HTTPS (secure) web server used for control and setup
• VNC server (implements RFB 3.3 protocol with Hextile encoding)
• Requires one dedicated IP address
  
• TCP/IP port numbers for all services may be changed to confuse attackers
• SMTP is used to deliver email notifications
• Does not require a DNS server (Domain Name Server) so that it will continue to operate in the face of this network failure

System Software

• Specialized RTOS (Real Time OS)
• Proprietary software, with published open-standard based interfaces System requirement

System Requirements

• Web browser - In order for the Kaveman to function correctly and encrypt keyboard and mouse data, users must have a Java environment that runs SSL. We recommend using Internet Explorer 6+ with the java plug-in JRE 1.4.1. Some other combinations of Netscape or Internet Explorer and the above-mentioned Java plug-in might work, but other versions have not been tested, so we take no responsibility for the outcome. Internet Explorer 5+ works without the plug-in, but does not support encrypted mouse and keyboard events, and will not support the new Java applet
• Optional VNC viewer - supports version 3.3 of RFB protocol. The VNC implementation must use bgr233 pixel format
• An SMTP server is required for email notification feature
• Telnet client required for serial port terminal server access

Public Keys / Encryption

• Supports X.509 certificates
• True hardware RNG (random number generator) used to create session keys and seed values
• 128-bit or 56-bit encryption for SSL v2
• Supports RC4 and DES algorithms
• Compatible with both import and export browsers

Special features

• Up to 32 unique password/users
• Stealth mode - prevents port scans and other network probes
• Turtle mode - disables self when attacked; requires access to local console to re-enable
• Idle timeout causes logout
• Multiple users can connect to same system
• Compatible with most existing KVMs
• Operating Environment 10°to 40° degrees C
• Storage Temperature -20°to 60° degrees C
