0078 - Card Temperature Exceeds Nominal lvl:T1
An HC-MIM card, EPM based card (E5-E1T1, E5-ATM, E5-ENET, E5-IPSM, E5-TSM), EPM-B based card (E5-ATM-B, E5-ENET-B, E5-MCPM-B), or E5-SM8G-B card has reached an operating temperature that is above the pre-defined limit.

** 0100.0078 ** CARD 1102 LIMT1 Card temperature exceeds nominal lvl:T1
Alarm Level: Major
Recovery
warning:
There is a very limited time to solve this problem. Once the card exceeds its operation limit, all the links on the HC-MIM card will be blocked (ACT-LPO), causing the links to go into local processor outage. All traffic on the blocked links is re-directed elsewhere in the system (based on the current route provisioning). For information about EPM based, EPM-B based, and E5-SM8G-B cards, see "Changing the High-Capacity Card Temperature Alarm Thresholds" procedure in Database Administration Manual - SS7.- Enter the following command to verify the temperature
threshold defaults are within the correct range for the card:
rtrv-th-alm
For HC-MIM cards, the maximum operating temperature is 82 degrees Celsius. For EPM based cards (E5-E1T1, E5-ATM, E5-ENET, ET-IPSM, E5-TSM), the maximum operating temperature is 95 degrees Celsius. For EPM-B based cards (E5-ATM-B, E5-ENET-B, E5-MCPM-B) and E5-SM8G-B cards, maximum operating temperature is 90 degrees Celsius. Temperature Level 1 threshold (Thermal Alarm Level 1) and Temperature Level 2 threshold (Thermal Alarm Level 2) are user configurable. Temperature Level 1 threshold can be configured between 73%–92% (default is 92%) of maximum operating temperature of the card and Temperature Level 2 threshold can be configured between 74%–100% (default is 100%) of maximum operating temperature of the card.
If the thresholds are set incorrectly (or to temporarily suppress the alarm), go to 2. If the thresholds are correct, go to 3.
- The threshold can be reset by entering the following
command:
chg-th-alm:thermallv1c=xxxx
where xxxx is temperature.
- Skip this step for EPM-based cards. Verify that the
fan assembly located in that shelf is working properly and that the fan filters
are clean.
- Check to make sure there is both A and B power.
- Check the fans.
- Check the fan controller card and verify that all
LEDs are green.
For proper operation (as a minimum B power must be present and good fans for fan 2 and fan 3 must be installed before removing the controller).
- Check the fan filters.
- Replace any hardware in the fan assembly that is not functioning properly. Clean or replace fan filters as needed.
- Replace the fan tray only after checking power,
fans, fan filters, and control card.

The hierarchy of maintenance activity is based on Table 3-2. See the Maintenance Manual for card removal/replacement procedures.
Table 3-2 Maintenance Activity Hierarchy
Condition Cntrl LED FAN 1 LED FAN 2 LED FAN 3 LED Alarm Status Actions Normal Operation Green Green Green Green No Alarm** None A power feed fail Blink RED Alarm* Check the fuse, the power source, and cables. Interconnect card OR circuit fail Blink RED Alarm* Check the fuse, the power source, and cables. B power feed fail Blink RED Alarm* Check the fuse, the power source, and cables. Fan 1 fail Green RED Alarm* Make sure that there is A power.
Make sure that there is B power and that Fan 2 and Fan 3 are operating properly.
Replace the fan.
Fan 2 fail Green RED Alarm* Make sure that there is both A and B power.
Make sure that Fan 1 and Fan 3 are operating properly.
Replace the fan.
Fan 3 fail Green RED Alarm* Make sure that there is B power.
Make sure that there is A power and that Fan 1 and Fan 2 are operating properly.
Replace the fan.
Fan 1 Removed Green Blink Alarm* Make sure that the fan is seated properly.
Replace the fan.
Fan 2 Removed Green Blink Alarm* Make sure that the fan is seated properly.
Replace the fan.
Fan 3 Removed Green Blink Alarm* Make sure that the fan is seated properly.
Replace the fan.
Controller card partial fail RED Alarm* Make sure there is both A and B power.
Make sure the fans are working properly.
Remove Fan 1.
Replace the Fan Tray Controller.
Controller card fail. OFF OFF OFF OFF Alarm* Make sure there is both A and B power.
Make sure the fans are working properly.
Remove Fan 1.
Replace the Fan Tray Controller.
Interconnect Failure Replace shelf. Note:
- * If there is no alarm for this condition, it is likely that the relay on the Interconnect card has failed (opened).
- ** If there is an alarm when all 4 LEDs are green, it is likely that the relay on the Interconnect card has failed (closed).
- Try replacing the controller before replacing the fan tray.
- If the fan unit is working properly, employ additional cooling methods to the card reporting a high-operating temperature.
- If the running temperature of the HC-MIM card, EPM based card (E5-E1T1, E5-ATM, E5-ENET, E5-IPSM, E5-TSM), EPM-B based card (E5-ATM-B, E5-ENET-B, E5-MCPM-B), or E5-SM8G-B card exceeds its operational limit, UAM 0077 is generated. HC-MIM links go into Local Processor Outage (LPO). For information about EPM based, EPM-B based, and E5-SM8G-B cards, see "Changing the High-Capacity Card Temperature Alarm Thresholds" procedure in Database Administration Manual - SS7.
- This Temperature Alarm will remain in the system until the operational temperature of the HC-MIM card (HC Blade), EPM based card (E5-E1T1, E5-ATM, E5-ENET, E5-IPSM, E5-TSM), EPM-B based card (E5-ATM-B, E5-ENET-B, E5-MCPM-B), or E5-SM8G-B card returns to normal levels.
- If performing the steps in this procedure did not clear the fault, contact My Oracle Support (MOS) for assistance.
- If the threshold was changed in
2
to temporarily suppress the alarm, enter the following command to reset the
threshold to the original setting:
chg-th-alm:thermallv1c=xxxx
where xxxx is temperature.
