Installing or Replacing a PoS Module
Software and Hardware Version Requirements
The PoS modules are compatible with "i"-series MSM modules only, but are compatible
with both Summit and "i"-series I/O modules. For the most current list of I/O modules
supported for use with the PoS modules, consult your release notes.
Software support for PoS modules is provided in an ExtremeWare technology release,
which is a software release providing specialized hardware support and/or additional
functionality not found in the current mainstream ExtremeWare release.
The ExtremeWare technology release that supports PoS modules includes multiple
software packages. One software package runs on the MSM module, while another
package runs on each PoS module. These software packages are downloaded
independently using the ExtremeWare
command. Each software
download image
package has an associated version number that you can display by using the
command. As a recommendation (not a requirement), the MSM software
show version
package and the PoS module software package should be the same version. To ensure
compatibility, the MSM performs an automatic compatibility check before a PoS module
is activated. In case of incompatibility, the PoS ports on the module will not come up
and the
command will indicate that the software on the PoS module is
show slot
incompatible with the software on the MSM.
You can also verify compatibility by comparing the version of the MSM software
package with the version of the PoS module 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 V6.1.5 (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 V6.1.5 (Build 20) to form the extended version identifier format. The first
field of the version identifier, ExtremeWare V6.1.5 (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, V1.2.64 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, 24, is the extended build version number.
