Vertiv™ Avocent® HMX High Performance KVM Extender System Installer/User Guide

1 Product Overview
The Vertiv™ Avocent® HMX Advanced High Performance KVM extender system is the next generation of Avocent keyboard,
video and mouse (KVM) products. The system offers flexible ways to link receivers, transmitters and systems via standard
networks.
1.1 Features and Benefits
The HMX 5000, 6000 and 8000 series extenders provide a high-performance, reliable desktop extension experience by
converting high quality DVI or DPand 4K video, audio and USB data into Internet Protocol (IP) messages. Via the included
web-based System Configuration utility, you can customize and enable audio options for the transmitters and receivers
throughout your system. All models support copper-based Gigabit Ethernet cabling and Fiber Channel over Ethernet (FCoE).
Dual models allow these to be used in parallel to provide additional Gigabit connection speeds as well as link redundancy that
maintains operation in the event of a failed connection.
The HMX high performance extenders support single-head video at single-link resolutions, but the dual models of both series
also support dual-head video at two single or one dual-link resolution. Within the HMX 6000 extender series, the HMX 6210T
extender also has a built-in Virtual Network Computing (VNC) server allowing it to stream low-bandwidth versions of high-
resolution output (via a dedicated Ethernet port). This allows remote access via a VNC viewer, through any standard network.
The HMX 8000 extender provides dual-head 4K video, audio and USBdelivered over a fiber connection.

Table 1.1 Model Descriptions
1.1.1 Additional video features
The HMX extender system allows you to choose how to compress video transmission across your network. The system is
automatically loaded with a lossless codec compression Run-Length Encoding (RLE) scheme which encodes or decodes a
digital data stream or signal to improve the appearance of natural images, gradients or shadows. If you do not need "pixel
perfect" results for your images, a compression scheme that can be added and configured to provide increased system speed.
Anti-dither capability
While the dithering process smooths the appearance of gradually shaded areas in video images, it can slow down system
performance. If using Apple Mac or other computers with dithered video output in your network, the HMX extender system
provides an anti-dither capability to increase performance and reduce network traffic.
NOTE: Enabling the anti-dither feature may produce slight color inaccuracies on the monitor.
1 Product Overview 1
Vertiv™ Avocent® HMX High Performance KVM Extender System Installer/User Guide

Extended Display Identification Data (EDID) management
The EDID is used to provide details to the monitor graphics card so it uses the optimal video resolution. With the HMX
extender system, you can use the EDID of the monitor connected to the receiver or use a fixed EDID that is stored on the
transmitter.
1.1.2 USB support
The HMX extender system transmitters use USB Emulation technology, which enables faster keyboard and mouse switching
for up to 13 different USB devices or an infinite amount of the same devices. This technology emulates certain USB peripheral
signals to the computer, causing those peripherals to appear permanently connected to the computer, even when the
receivers are switched elsewhere. Other supported USB devices include Human Interface Devices (HID), storage devices
such as flash drives and various printers, scanners and serial adaptors.
NOTE: The HMX extender system does not support isochronous USB devices such as microphones, speakers,
webcams and television receivers.
1.1.3 Transport Layer Security (TLS)
The HMXextender system supports the industry standard TLS protocol which offers protection against third party
monitoring and tampering when data is transferred across networks.
1.1.4 Vertiv™ Avocent®HMX Advanced Manager software
The HMX Advanced Manager software is a secure, web browser-based, centralized, enterprise management solution that
provides remote management and monitoring of the extender system. The software handles all administration, access control,
monitoring and firmware upgrades across the extender system. For more information on the HMX Advanced Manager
software, see the Vertiv™ Avocent®HMX Advanced Manager Software Installer/User Guide.
NOTE: When using the HMX Advanced Manager software server to configure your HMX extender system, ensure that
all transmitters and receivers are set to their factory defaults. Otherwise, they will not be located by the HMX
Advanced Manager server.
1.2 Extender System Devices
Within the HMX extender system, transmitters and receivers allow you to seamlessly access and share one or more remote
computers that are physically separated from your local work environment.
1.2.1 Extender interfaces
Administrators and users can manage and configure transmitters and receivers in the extender system through a web-based
System Configuration utility. Receivers within the system also have an On-Screen Display (OSD) that allows users to establish
target connections from a local keyboard and mouse.
1.2.2 Firmware upgrades
Transmitters and receivers are flash upgradable at any time to ensure that your system is running the most current version
available. If your system is running the most current firmware version and is managed by the HMX Advanced Manager
software, then that same version must be used across all units in your system. Firmware versions can be mixed in
configurations not using the HMX Advanced Manager software, but it is always recommended to use the most current
version.

1.2.3 Device ports
Transmitters and receivers in the HMX extender system share similar port layouts and functionality. After the general
descriptions provided in this section, the following graphics illustrate where these ports and other features are located on the
transmitters and receivers. For more information on configuring and working with these ports, see System Configuration
Utility on page23.
System and Teaming ports
The system port on transmitters and receivers is the default location to connect devices in either a direct connect
configuration or a matrix configuration. On HMX extender dual-head models, the teaming port can be used in conjunction
with the system port to provide immediately increased connection speeds of up to 2 Gigabits per second. On HMX8000
models, you can use two 10gb fiber cables for connection speeds up to 20 GB per second. Using these ports together also
improves video, audio and peripheral feed quality, increases bandwidth in your system and creates link redundancy that can
maintain operation in the event of a failed connection. The web-based System Configuration utility can be accessed from
either port, although the system port is the default location.
Serial port
The AUX serial port on transmitters and receivers allows RS232 signals to be extended up to a baud rate of 115200.
1.2.4 Management and VNC ports
HMX extender dual-head transmitters and receivers have a port on the left side of the front panel. For the HMX 6210T
transmitter, this port is a VNC port that transmits low-bandwidth video output to authorized remote viewers. On the remaining
dual-head models, this port is a management port that allows you to access the System Configuration utility if the system port
is already in use due to the extenders operating in a direct connect configuration.

2.2 System Recommendations
For optimal performance, it is recommended that your HMX extender system has the following:
2 Installation and Configuration
14
Vertiv™ Avocent® HMX High Performance KVM Extender System Installer/User Guide

•Ethernet ports that support Gigabit (1000 Mbps) or faster speeds
•Internet Group Mulitcast Protocol (IGMP) v2 or v3 support
•Jumbo frame that supports up to 9216 bytes
•Fiber channel or other high bandwidth connections between switches
•Layer 3 switches with full duplex, 1 Gbps up and downstream speeds and multiple dedicated processors
Application Specific Integrated Circuits (ASICS)
•For HMX8000 models, a 10 GBfiber connection is required
2.2.1 Factory reset
If the standard settings within your HMX extender system are changed in an installation and you need to change the current
configuration, a reset must be performed to restore the transmitters and receivers to the factory default settings before
proceeding. This factory reset must also be performed if using an HMX Advanced Manager server to configure your system.
Otherwise, the transmitters and receivers in the managed system will not be located.
To perform a factory reset:
NOTE: A factory reset can also be performed from the System Configuration utility. For more information, see System
Configuration Utility on page23.
1. Ensure the extender you are resetting is turned on.
2. On the extender front panel, locate the small hole that houses the recessed reset button.
3. For HMX5000 and 6000 units, insert a narrow tool such as a straightened paper clip into the hole, then press
and hold it while removing the power cord. Re-insert the power cord and then release the reset button. Five of
the front panel device status indicators quickly flash nine times to indicate a successful reset.
-or-
For HMX6500 units, press and hold the button next to the front panel OLEDscreen until the indicator turns blue
and the OLEDscreen displays that the unit is in factory reset mode. Then use a narrow tool such as a
straightened paper clip to press and release the recessed button on the front panel to turn the unit off. Wait 10
seconds and press the button again to turn the unit back on.
-or-
For HMX 8000 units, use a narrow tool such as a straightened paper clip to press and hold the recessed reset
button until the indicators turn blue. Indicators will flash red and green before turning blue. Release the reset
button. The indicator remains blue as the unit resets itself. The indicator illuminates green when all connections
are reset or orange if one of the connections are missing.
NOTE: You must wait at least 30 seconds after you have released the reset button to safely disconnect power.
2.3 Basic Configuration
After your system is installed and turned on, you may need to re-configure the IP address for your network. In a direct connect
configuration, the factory default address may be acceptable for immediate use in your network. However, if you wish to
change the default address, this should be the only basic configuration needed to begin using your transmitter and receiver.
In an unmanaged matrix configuration, the IP address of the transmitter and each receiver must be specified so the units can
locate each other within the HMX extender system. Re-configuring the IP addresses of extenders in a managed matrix
configuration is completed in the HMX Advanced Manager software. See the HMX Advanced Manager Software
Installer/User Guide for basic configuration procedures. The default port IPaddresses are listed in the following table.
