10.1.1.1 Heartbeat
The shelf managers use two private interfaces to heartbeat each other. The heartbeat interval
is configured to 400 ms and the partner is considered inactive when no responses are received
after five retries within 2 seconds.
10.1.1.2 Data Replication
During redundant operation, the active shelf manager synchronizes the shelf FRU information
with the standby shelf manager every time it is modified using an HPI application (for example,
shelf address, shelf IP address, shelf manager controlled activation, allowance for FRU
activation readiness, FRU activation order).
While the shelf manager is inserted, the active shelf manager synchronizes the shelf FRU
information with the newly inserted shelf manager.
The active shelf manager replicates HPI resource IDs on the standby shelf manager during
redundant operation and during shelf manager insertion.
10.1.1.3 HPI Interface
The HPI interface for the Redundancy Sensor and the Heartbeat Sensor is implemented as
described in the
HPI-to-AdvancedTCA Mapping Specification
.
10.1.2 System Manager
If the system manager accesses the active shelf manager via the backplane Ethernet interfaces,
it may use virtual IP plane and active virtual IP address 192.168.0.171 of the shelf manager.
The change of shelf address, shelf IP address and FRU activation order takes effect after a
reboot of the system (powering down and up again which means a physical toggle of the
PSU/PEM breakers).
