Cooling System Failure; Ethernet Port Failure - HP HSR6800 Installation Manual

Cooling system failure

When the temperature inside the router exceeds the upper threshold, the following information appears
on the configuration terminal:
#Jun 14 11:54:38:178 2012 HP DEVM/1/BOARD TEMPERATURE UPPER:
Trap 1.3.6.1.4.1.25506.8.35.12.1.16<hhpBoardTemperatureHigher>: chassisIndex i
s 0, slotIndex 0.1
%Jun 14 11:54:38:179 2012 HP DEVM/4/BOARD_TEMP_TOOHIGH: Board temperature is to
o high on Chassis 0 Slot 1, type is RSE-X2.
The output shows that the temperature inside the router has exceeded the upper threshold. In this case,
the fans of the router will rotate at full speed.
Generally, after the fans rotate at full speed for a certain period, the temperature inside the router will
drop below the upper threshold, and the following information appears on the configuration terminal:
#Jun 14 11:56:48:279 2012 HP DEVM/1/BOARD TEMPERATURE UPPER:
Trap 1.3.6.1.4.1.25506.8.35.12.1.17<hhpBoardTemperatureFormHigherToNormal>:
chassisIndex i
s 0, slotIndex 0.1
%Jun 14 11:56:48:279 2012 HP DEVM/4/BOARD_TEMP_TOOHIGH: Board temperature changes to
normal on Chassis 0 Slot 1, type is RSE-X2.
The output shows that the operating temperature of the router restores to normal state.
When exceptions occur, the temperature inside the router might exceed the critical temperature threshold,
and the following information appears on the configuration terminal in this case:
%Jun 14 12:06:58:436 2012 HP DRVMSG/3/TempCritical:
CPU temperature is greater than alarm upper limit in slot 1, index is 1
At the same time, the ALM LED of the MPU is red, which indicates that the temperature inside the router
is abnormal.
To troubleshoot the cooling system failure:
1. Verify that the fans are running correctly.
2. Verify that the operating environment of the router is well ventilated.
3. Use the display environment command to check whether the temperature in the router keeps rising.
4. If the temperature inside the router exceeds the critical temperature threshold, but the fans are
running correctly and the router is well ventilated, power off the router immediately and contact
your local sales agent.
For more information about the display environment command, see HP HSR6800 Routers Fundamentals
Command Reference.

Ethernet port failure

When you use unshielded twisted pairs to connect Ethernet ports and at least one end of the link supports
100Base-TX, you should consider the rate matching of both ends. If the rates of the two ends do not
match (one end operating at 100 Mbps and the other end operating at 10 Mbps), the following failures
occur:
