INSTALLATION REQUIREMENTS
• The minimum permissible rmware versions for ALIF units linked with the A.I.M.
server depend upon the rmware version that is running on the A.I.M. server itself:
• A.I.M. server: v4.0 Attached ALIF endpoints: v3.5 (minimum)
• A.I.M. server: v4.1* Attached ALIF endpoints: v4.1 (minimum)
• A.I.M. server: v4.2* Attached ALIF endpoints: v4.2 (minimum)
* A.I.M. servers with rmware version 4.1 or above no longer support the original ALIF1000.
• On the network switch(es) that have A.I.M. server(s) attached, ensure that the portfast
option is enabled on each port to which an A.I.M. unit is connected. Where portfast
is not enabled, if a second A.I.M. is added for redundancy, this could result in a mis-
congured back up server.
• If an existing A.I.M. server must be replaced, follow the important advice given within
Appendix C (Swapping out an A.I.M. server).
• When conguring the installation for multicasting (and to improve overall
performance), the network switch(es) being used must support a minimum of IGMP v2
snooping. For faster performance use switches that support IGMP v3.
• In order to display video resolutions that use a horizontal video resolution of 2048
pixels, the network switch must have support for Jumbo packets.
• Please also see Appendix A - Tips for success when networking ALIF units.
• This unit should always be installed in suitable a 19” rack space, it is not suitable for
standalone desktop use.
