3.2 INSTALLATION REQUIREMENTS
• The minimum permissible firmware versions for Agility units linked with the iPATH server depend upon the firmware version
that is running on the iPATH server itself.
Note: iPATH servers with firmware v4.1 or above no longer support the original Agility model.
• iPATH server: v4.0
• iPATH server: v4.1
• iPATH server: v4.2
• iPATH server: v4.3
• iPATH server: v4.4
• iPATH server: v4.5
• iPATH server: v4.6
• iPATH server: v4.7
• iPATH server: v4.8
* Due to the changes made to Agility v4.4 endpoint code to support 4 bit Flash error checking, it is not possible to downgrade
from v4.4 endpoint code. Therefore, v4.4 iPATH has been designed to run with both v4.3 and v4.4 endpoint code. These are
both identical in functionality, but v4.4 endpoint code uses 4-bit ECC flash and v4.3 uses 1-bit ECC flash.
To upgrade to v4.5 endpoint code, it is necessary to first upgrade to v4.4. Once at v4.4, it is not possible to downgrade.
§
However, v4.5 does allow a downgrade to v4.4.
• Portfast needs to be enabled on the network switch to ensure that the Agility to iPATH communication happens in a timely
manner. Note that Cisco uses the term 'edge port' rather than 'port fast'. The option is enabled on each port to which an
iPATH unit is connected. Where portfast is not enabled, if a second iPATH is added for redundancy, this could result in a mis-
configured Backup server.
• If an existing iPATH server must be replaced, follow the important advice given within
