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.

Example

RLGHNCXA21W 00-02-07 11:02:30 EST  EAGLE 35.0.0
** 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.

1. 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.

2. The threshold can be reset by entering the following command:
   chg-th-alm:thermallv1c=xxxx

   where xxxx is temperature.

3. 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.

     Contact My Oracle Support (MOS) for assistance.

   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.
4. If the fan unit is working properly, employ additional cooling methods to the card reporting a high-operating temperature.
5. 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.
6. 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.
7. If performing the steps in this procedure did not clear the fault, contact My Oracle Support (MOS) for assistance.
8. 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.
