Installing or Replacing an ARM

Software or Hardware Version Requirements

ARMs are compatible with "i" -series MSM modules, Summit and "i" -series I/O
modules, and Packet over SONET (PoS) modules. For the most current list of I/O and
PoS modules supported for use with the ARMs, consult your release notes.
Software support for the ARM is provided in an ExtremeWare technology release, which
is a software release that provides specialized hardware support or additional
functionality not found in the current mainstream ExtremeWare release.
The ExtremeWare technology release that supports the ARM includes multiple software
packages. One software package runs on the MSM module while another package runs
on each ARM. The software packages are downloaded independently using the
ExtremeWare command. Each software package has an associated
download image
version number that you can display using the command. As a
show version
recommendation (not a requirement), the MSM software package and the ARM
software package should be the same version. To ensure compatibility, the MSM
performs an automatic compatibility check before an ARM is activated. In case of
incompatibility, the ARM ports on the module will not come up and the
show slot
command will indicate that the software on the ARM is incompatible with the MSM
software.
You can also verify compatibility by comparing the version of the MSM software
package with the version of the ARM software package. The format of the software
version field of the ExtremeWare software version identifier has been extended to
support technology releases. The following example of the ExtremeWare software
version identifier illustrates the extended version format:
ExtremeWare Version 6.1.5 (Build 20) Project IP_SERV_TECH_REL v1.2.64
In this example, the technology release-specific version information Project
IP_SERV_TECH_REL v1.2.64 is added to the base ExtremeWare version identifier
ExtremeWare Version 6.1.5 (Build 20) to form the extended version identifier format. The
first field of the version identifier, ExtremeWare Version 6.1.5 (Build 20), identifies the
ExtremeWare software version on which this technology release is based. The second
field in the extended version identifier, Project IP_SERV_TECH_REL, is the name of the
technology release. The final field 1.2.64, is a three-part number that identifies the
version of the technology release. In the example, the first part of the number, 1, is the
extended major version number; the second part of the number, 2, is the extended minor
version number; the third part of the number, 64, is the extended build version number.
The MSM software package is compatible with the ARM software package when the
following conditions are true:
