Temperature Sensor; Reset Button - HP 9304m Installation And Getting Started Manual

100BaseFX Ports
The 100BaseFX ports are equipped with MT-RJ connectors and operate at 100 Mbps in full-duplex mode.
1000BaseSX Ports
The 1000BaseSX ports operate in full-duplex mode and are equipped with SC connectors on fixed-configuration
modules and can be mini-GBICs with LC connectors for mini-GBIC modules that support this port type. Multi-
mode fiber cabling is supported.
1000BaseLX
The 1000BaseLX ports operate in full-duplex mode and are equipped with SC connectors on fixed-configuration
modules and come as mini-GBICs for mini-GBIC modules that support this port type. Both single-mode fiber
(SMF) and multi-mode fiber (MMF) cabling is supported. The 1000BaseLX ports must be connected to another
1000BaseLX port. Connection to a 1000BaseSX port is not supported.
NOTE: 1000BaseSX and 1000BaseLX ports also support auto-negotiation when the auto-gig option is enabled
on the system.
NOTE: 1000BaseSX and 1000BaseLX ports operate only at full-duplex.
Port Connectors
• 10/100BaseTX ports come with RJ-45 connectors.
• 100BaseFX ports come with MT-RJ connectors.
• 1000BaseSX and 1000BaseLX ports come with dual SC connectors.
• 1000BaseSX and 1000Base-LX ports also can be mini-GBIC ports with LC connectors for the modules that
support mini-GBICs and these interface types.

Temperature Sensor

The redundant management modules contain an on-board temperature sensor. The software reads the sensor
based on the chassis poll-time, a configurable parameter that determines how often the software polls the chassis
for hardware status information.
The software is configured with a warning temperature (default 45 degrees Celsius) and a shutdown temperature
(default 55 degrees Celsius). When the software reads the temperature sensor, if the temperature equals or
exceeds the warning or shutdown temperature, the software does the following:
• Warning message – If the temperature of the module reaches the warning value, the software sends a Syslog
message to the Syslog buffer and also to the SyslogD server, if configured. In addition, the software sends an
SNMP trap to the SNMP trap receiver, if you have configured the device to use one.
• Shutdown – If the temperature matches or exceeds the shutdown temperature, the software sends a Syslog
message to the Syslog buffer and also to the SyslogD server if configured. The software also sends an
SNMP trap to the SNMP trap receiver, if you have configured the device to use one.
If the temperature equals or exceeds the shutdown temperature for five consecutive polls of the temperature by
the software, the software shuts down the module to prevent damage.
For more information and configuration information, see "Using the Temperature Sensor" on page 4-44.

Reset Button

The reset button allows you to restart the system. The reset button is recessed to prevent it from being pushed
accidentally. The reset button is located to the right of the serial port on the management module as labeled in
Figure B.4.
