In addition to bug fixes, the AXP 1.5.2 maintenance release builds upon AXP 1.5.1- see the blog 'AXP 1.5.1 Release - A Giant Leap Forward' - by adding support for two new service modules. The SRE 700 has a 1.86 GHz cpu, 4 GB Ram, and a 500 GB HD. The SRE 900 offers Raid 1 support, has a 1.86 GHz dual core cpu, 4 GB RAM and 2x500 GB HD. Raid-1 and linear raid can be selected as options at install time. This new hardware runs on the new Cisco Generation 2 routers which require IOS require IOS version 15.0(1)M or higher
Backed by popular request a new internal interface (mgf) has been added to allow for inter-blade (i.e., AXP to AXP) communication within the same router.
