5.6 CPU Host Software Upgrade Procedure
This section provides procedures for upgrading Integrated Access System host software. The
procedures for upgrading from 5.0.0 to 5.2.0, and from 5.0.1, 5.0.2, or 5.1.1 to 5.2.0.
The CPU-5 XCON card contains the host software that controls the Integrated Access System.
The host software is stored in flash memory facilitating download of future software releases
to the CPU card. Host firmware for the CPU-5 currently has five versions: 5.0.0, 5.0.1, 5.0.2,
5.1.1 and 5.2.0.
Version 5.0.0 of the host software utilizes kernel 5.0.0, while versions 5.0.1, 5.0.2, 5.1.1 and
5.2.0 host software use kernel 5.0.1. To upgrade from 5.0.0 to 5.2.0 host, the CPU(s) must be
replaced with CPU(s) that contain the new 5.0.1 or 5.2.0 host software containing the new
5.0.1 kernel. CPUs with 5.0.1 host software already use the 5.0.1 kernel and can be upgraded
by flash download as outlined in the procedures in Section 5.7 on page 5-44.
