2.1 Blade Installation and Removal
Note: It is important that the module be properly aligned with the slot guides before it is
inserted into the appropriate slot on the chassis. It is recommended that the user’s
line of sight be level with the middle of the backplane in order to see both slot
guides clearly.
Install a VSI blade into the chassis as follows:
Caution: Use proper ESD precautions when installing or removing a VSI blade to
avoid damaging the unit’s circuitry.
1. Slide the blade, open end first, into the desired slot on the chassis until it plugs into the
connector located on the backplane at the rear of the unit.
2. Use the bottom ejector handle to securely seat the blade into the chassis and to properly
mate the rear connectors. The handle should lock closed when properly inserted to secure
the unit.
3. Tighten the captive thumb screw located at the top of the blade to provide a more secure
mounting.
4. If desired, an additional Phillips screw can be installed through the handle.
5. The Status LED will blink once per second when the blade is properly installed, powered, and

Chapter 3 Connecting to the Network AVN422HD User’s Manual
Chapter 3 Connecting to the Network
3.1 Unicast and Multicast Transmissions over the Network
A Unicast transmission sends IP packets to a single recipient on a network. A Multicast
transmission sends IP packets to a group of hosts on a network. If the streaming video is to be
distributed to a single destination, then you would start a Unicast stream by setting the
destination IP address and port on the AVN equal to the destination's values. If you want to view
the stream at multiple concurrent locations, then you would set the AVN's destination IP address
to a valid Multicast IP address (224.0.0.0 - 239.255.255.255).
Note that while the Multicast IP address range is from 224.0.0.0 - 239.255.255.255, the first octet
(224.xxx.xxx.xxx) is generally reserved for administration. VSI recommends setting the first octet
to 225 and the remaining three octets to the AVN's IP address. For example, if the AVN's IP
address is 192.168.1.53, then set the destination IP address to 225.168.1.53 for Multicast
streaming.
Since Multicasting is a relatively new technology, some legacy devices that are part of your
network might not support Multicasting.
Before using the AVN422HD in Multicast streaming mode, check the functional specifications of
your network infrastructure to ensure that the Multicast stream will not create major traffic on your
network. Verify that your backbone switch supports Internet Group Messaging Protocol (IGMP)
snooping, which allows the core of your network to ignore the traffic streams that Multicasting
may generate.
3.2 IGMP Querying and IGMP Snooping
IGMP is a session-layer (Layer 3) protocol used to establish membership in a Multicast group
and can register a router to receive specific Multicast traffic. (Refer to RFC 1112 and RFC 2236
for information on IGMP versions 1 and 2.)
Multicast aware switches are slowly making their way into the network cores for businesses and
universities that have heavy traffic to move through their networks. Multicast filtering is achieved
by dynamic group control management. By default, all Multicast traffic should be blocked until
requested by a Multicast group member. (Default behavior depends on switch manufacturer.)
The master of the IGMP filter lists is the router or switch that is configured to act as the IGMP
Querier. The responsibility of the Querier is to send out IGMP group membership queries on a
timed interval, to retrieve IGMP membership reports from active members, and to allow updating
of the group membership tables.
A Layer 2 switch supporting IGMP Snooping can passively snoop on IGMP Query, Report, and
Leave (IGMP version 2) packets transferred between IP Multicast routers/switches and IP
Multicast hosts to determine the IP Multicast group membership. IGMP snooping checks IGMP
packets passing through the network, picks out the group registration, and configures
Multicasting accordingly.
8
AVN422HD User’s Manual Chapter 3 Connecting to the Network
Without IGMP Querying/Snooping, Multicast traffic is treated in the same manner as a Broadcast
transmission, which forwards packets to all ports on the network. With IGMP Querying/Snooping,
Multicast traffic is only forwarded to ports that are members of that Multicast group. IGMP
Snooping generates no additional network traffic, which significantly reduces the Multicast traffic
passing through your switch.
If your network distribution core does not support IGMP Querying/Snooping, the AVN streams
will still function as designed but your network may be subjected to high traffic loads and
condensed collision domain due to the broadcasting action used by the older switch or hub. If this
is the case, you may wish to isolate the streaming nodes within the network so that the streams
may be viewed without crossing the normal network traffic along its path.
Otherwise, for a general performance improvement, you may consider upgrading your network
core to a switch that is Multicast aware.
3.3 DHCP IP Configuration
The AVN422HD has Dynamic Host Configuration Protocol (DHCP) enabled as the factory
default. If your network has a DHCP server on it, the AVN422HD will automatically acquire an IP
address. If the AVN422HD is not able to find a DHCP server, it will default to the IP Address,
Subnet Mask and Gateway that are configured into the unit. The factory default IP address is
192.168.1.253.
To disable or enable DHCP on the AVN422HD, use either the Console Interface (refer to section
) or the Browser Interface (refer to section 6.5.3 Device Network).
To assign a static IP address for the AVN422HD, refer to the following section.
3.4 Static IP Configuration
If the AVN422HD is not able to find a DHCP server, it will default to the IP Address, Subnet Mask
and Gateway that are configured into the unit. The factory default is 192.168.1.253.
It is strongly recommended that the AVN422HD be statically configured to a specific IP address.
This enables the AVN422HD to be consistently found at the same address. Prior to statically
configuring the AVN422HD, check with your IT department and/or make sure the IP address to
be assigned is not in use by any other device on the LAN.
To assign a static IP address to the AVN422HD, follow these steps:
1. Power on the AVN422HD blade and connect the console (light blue) and the network cables.
2. Run a terminal emulation program such as HyperTerminal or Minicom to communicate via
console (refer to section 5.1 Connecting With a HyperTerminal Session). Use the following
communication parameters: Bits per second (38400), Data bits (8), Parity (None), Stop bits
(1), Flow Control (None).
3. Press Enter to get the login prompt.
9
Chapter 3 Connecting to the Network AVN422HD User’s Manual
4. Log in to the unit with the valid username/password (by default admin/admin).
5. An unconfigured unit automatically starts the Network Configuration Wizard, and will prompt
the user to enter an IP Address, Netmask, Gateway, and DNS Server.
6. Once the values have been entered, the AVN422HD should reboot and be accessible at its
newly assigned address. Type the unit’s IP address into a browser (http://xxx.xxx.xxx.xxx) to
bring up the AVN422HD’s Browser Interface (refer to Chapter 6 Using the Browser Interface).
7. For previously configured units, press “n” and then Enter from the Console Interface to
unlock the display and start the Network Configuration Wizard (see step 5 above).
8. Units can be reconfigured at any time using the Console Interface as described in the
previous step.

AVN422HD User’s Manual Chapter 5 Using the Console Interface
5.2.1 Network Configuration
An AVN422HD is considered to be either configured or unconfigured depending upon previous
actions.
— An unconfigured unit does not have any network configuration settings. When the
Console Interface is opened for the first time, the Network Configuration Wizard
automatically appears and prompts the user to enter four pieces of information: the IP
Address, Netmask, Gateway and DNS Server values.
— A configured unit is one where the network configuration settings have been entered
and saved. When the Console Interface is opened on a configured unit, it will display the
basic network information about the unit and that it is in a “Locked” state. To change any
of the current values, the user will need to unlock the Console Interface and activate the
Network Connection Wizard. Doing this will automatically resets the network
configuration settings back to the unconfigured state.
If any typing errors occur during the configuration steps, just press the Enter key and re-enter the
desired values.
5.2.2 Using the Network Configuration Wizard
1. Open the Console Interface.
a. If configuring an unconfigured unit, the Network Configuration Wizard appears; or
b. Press n (lower case “n”) followed by the Enter key to unlock the display and open the
Network Configuration Wizard.
2. Please Enter Unit IP Address:
a. To configure the unit statically (recommended), enter the AVN’s new IP address and
press Enter.
b. To enable DHCP on the unit, enter 0.0.0.0 and press Enter.
3. Please Enter Unit Netmask: Enter the AVN’s new Netmask address, commonly
255.255.255.0, and press Enter.
4. Please Enter Unit Gateway: Enter the AVN’s new Gateway address. This value is critical for
updating firmware as it enables the AVN to find the Internet and download updates as
needed.
5. Please Enter DNS Server: Enter the AVN’s new DNS Server address, commonly 4.2.2.1,
and press Enter.
To restart the entire configuration, press n (lower case “n”) followed by the Enter key.

Field Upgrade).
Note: In order to upgrade firmware components, the AVN422HD must have a valid
Gateway IP address configured and be on a network that has access to the
Internet.
The AVN422HD has four firmware components:
1. Root File System
2. Linux Kernel
3. U-Boot Boot Loader (Boot Loader)
4. Configuration Partition (not currently implemented).
Each firmware component must be updated independently, but not all components will always
need to be updated. The Root File System is the most likely to change, and therefore the most
likely to require updating. If two or more image/components need to be updated, the updates
33
Chapter 6 Using the Browser Interface AVN422HD User’s Manual
must be performed in the order specified above (1. Root File System, 2. Linux Kernel, 3. Boot
Loader, and 4. Configuration Partition).
Warning: Failure to upgrade the firmware components in the proper order can
cause the AVN422HD to become non-operational and require that it
be reprogrammed by VSI at customer’s expense.
However, only out-of-date components need to be updated. For example, if both the Root File
System and the Boot Loader components are out-of-date, update the Root File System
component first and the Boot Loader second. The Linux Kernel, which is not out-of-date in this
example, would not need to be updated. If it did, update it after the Root File System and before
the Boot Loader.
Component – Displays the current firmware component name.
Installed Version – Displays the current firmware component version information.
Latest Available Version – Displays the most current firmware component version available.
Note: The Latest Available Version column and Upgrade Latest buttons are only

from the public Internet.
Actions:
Upgrade Latest – This button causes the corresponding component to be upgraded to the latest
version. After each upgrade, the AVN422HD automatically reboots.
Upgrade Custom Image – This button is for advanced users only and requires specific
component files in order to work properly. **IMPORTANT** Improper use of this option can
seriously impair the functionality of the AVN422HD, requiring it to be returned to VSI for
repair at the customer’s expense.

7.3 Factory Default Settings
This procedure provides a way to reset the AVN422HD configurations back to the factory default
settings, which may be necessary or desirable in certain circumstances.
If restoring the Factory Default, it is recommended that it be performed through the Browser
Interface as described in section 6.7.4 Administration FactDef.The unit will reboot to its Factory
Default settings. Note that a Factory Reset causes all of the settings, including the network
settings, to be reset to Factory Default values. Performing a Factory Default reset will restore the
DHCP settings to DHCP-On, causing the unit to acquire a new IP address. If there is no DHCP
server available on the network segment, the AVN422HD will automatically reset to default IP
address 192.168.1.253.
35
Chapter 7 Troubleshooting AVN422HD User’s Manual
However, if necessary (possibly due to lack of ability to communicate with the unit due to
misconfiguration), a hardware reset procedure is provided below.
To return the AVN422HD to the Factory Default settings:
1. Remove the AVN422HD blade from the chassis (see 2.1 Blade Installation and Removal).
2. Locate the Factory Default DIP switch near the top center of the AVN422HD blade's PCB.
3. If present, remove the plastic cover from the DIP switch.
4. Set the left DIP switch into the Factory Default position as labeled on the unit.
Warning: Do not change the position of the other dip switch.
5. With the chassis powered on, insert the AVN422HD blade back into the chassis.
Warning: Do not remove the blade or turn off power to the unit until the default
is complete as described below.
6. Observe the Status and Video LEDs on the front of the unit.
7. Wait for these lights to be "solid" on (no blinking); this indicates that the default reset is
complete.
8. Remove the blade from the chassis to return the DIP switch to the Normal Operation setting,
then re-install the blade.

AVN422HD User’s Manual Chapter 8 Field Upgrade
Chapter 8 Field Upgrade
8.1 Firmware Component Overview
The AVN422HD h.264 encoder blade is built on top of an embedded Linux software platform.
The Overall functionality of the system software is best looked at in four distinct pieces.
1. Root File System. The Root File System contains all of the necessary scripts and libraries
for Linux, as well as all of the additional value added software for user interfaces, encoding
and streaming control, and everything else that runs outside of the context of the Linux
Kernel.
2. Linux Kernel. The Linux Kernel is the core of the running system after control is handed over
by the Boot Loader. The Linux Kernel is responsible for virtualizing access to the underlying
hardware and controlling all of the running processes in the system.
3. U-Boot Boot Loader. The U-Boot Boot Loader (Boot Loader) is responsible for early system
initialization and configuration. It allows for updating and system configuration, but is locked
down to prevent system level accidents.
4. Configuration Partition. Not currently implemented.
8.2 Firmware Component Versions
In order to determine if a firmware upgrade is required, you will need two pieces of information:
namely what is currently installed and what is available. This is most easily done through the
Browser Interface as you can view both the current versions and the latest versions that are
available.
8.2.1 Browser Interface: To Determine Both the Current and Latest Version
Information
1. Open the Browser Interface.
2. Navigate to the Administration Upgrade page (refer to section 6.7 Administration Page).
This will display both the Current Version and Latest Version component information.
8.2.2 Via the Internet: To Determine the Latest Available Firmware Component
Version
1. Open a browser.
2. Go to http://www.vsicam.com/files/AVN4XX/LATEST/versions_HD.txtto view the latest
released firmware component versions (images) and their release dates.
37
Chapter 8 Field Upgrade AVN422HD User’s Manual
8.3 Updating Firmware Components
Each firmware component must be updated independently, but not all components will always
need to be updated. The Root File System is the most likely to change, and therefore the most
likely to require updating. If two or more image/components need to be updated, the updates
must be performed in the following order:
— Root File System
— Linux Kernel
— Boot Loader, and
— Configuration Partition (not currently implemented).
Warning: Failure to upgrade the firmware components in the proper order can
cause the AVN422HD to become non-operational and require that it
be reprogrammed by VSI at customer’s expense.
However, only out-of-date components need to be updated. For example, if both the Root File
System and the Boot Loader components are out-of-date, you would update the Root File
System component first and the Boot Loader second. The Linux Kernel, which is not out-of-date
in this example, would not need to be updated. If it did, you would update it after the Root File
System and before the Boot Loader.
Only one firmware component can be updated at a time.
8.3.1 General Firmware Component Update Procedure
Note: In order to use the general firmware component update procedures, the
