Temperature Sensor; Management Redundancy - HP ProCurve 9304M Installation And Configuration Manual

Installation and Basic Configuration Guide
• Three T-Flow Switching Processor (TSPs) – The TSPs perform Layer 2 and Layer 3 switching for the
forwarding modules.
The MP and the TSP have their own flash memory with primary and secondary areas.
Figure 4.2 illustrates the architecture of the T-Flow.

Feature Coexistence
The T-Flow architecture allows all the following features to be configured and active on a given port at the same
time.
• Input ACLs
• Input rate limiting
• NetFlow Export
• sFlow Export
• Network Address Translation (NAT)
• Policy-Based Routing (PBR)
• Output ACLs
• Output rate limiting
When two or more of these features are applicable for a packet, the T-Flow processes the features in the order
listed above.

Temperature Sensor

The T-Flow also contains a temperature sensor. The sensor generates a Syslog message and SNMP trap if the
module's temperature exceeds a specified warning level or shutdown level. You can use the CLI or Web
management interface to display the management module's temperature and to change the warning and
shutdown temperature levels. See "Using the Temperature Sensor" on page 6-48.

Management Redundancy

The T-Flow supports management redundancy. You can install a second T-Flow to act as a backup and take over
management of the Chassis device if the active T-Flow becomes unavailable.
