Xdensity Load Module Specifications

Xdensity Four User Support

As many as Four users can operate on a single Xdensity load module. A user can own from one to four port resource groups per load module. 32 ports of Xdensity is divided into four resource groups and each resource group consists of 8 ports defined as follows:

Resource group 1: Ports 1-8 (Port 1 is resource group Master)
Resource group 2: Ports 9-16 (Port 9 is resource group Master)
Resource group 3: Ports 17-24 (Port 17 is resource group Master)
Resource group 4: Ports 25-32 (Port 25 is resource group Master)

A user can own non-consecutive resource group (i.e. resource group 1 and resource group 4). Port Cluster specifications are as follows:

A Port Cluster may be owned by exactly one user
Taking ownership of any un-owned port within the port cluster will automatically force ownership of the entire Port Cluster. Ownership of some (but not all) ports within a Port Cluster is not a legal condition.
Releasing ownership of any owned port within a Port Cluster will automatically force release of ownership of all ports within that Port Cluster.
Reboot of CPU must take place through the Resource Group Master. If user wish to reboot for example port two entier resource group that is port one to port eight gets re-booted.
User can only Telnet to a Resource Group Master
Frequency adjustment (PPM Adjust) functionality is available across the entire Xdensity load module. If there is one owner across an entire Xdensity load module then the user will be allowed to change PPM value for the card. If more than one user owns Port Clusters across an Xdensity load module, then PPM cannot be changed by anyone.
