0077 - Card Temperature is Critical lvl:T2

An HC-MIM card, EPM based card (E5-E1T1, E5-ATM, E5-ENET, ET-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 operational limit.

Example

RLGHNCXA21W 00-02-07 11:02:30 EST  EAGLE 35.0.0
*C 0100.0077  *C CARD 1102  LIMT1 Card temperature is critical lvl:T2

Alarm Level: Critical

Recovery

WARNING:

There is a very limited time to solve this problem. For an HC-MIM card, 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. 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 3-1. See the Maintenance Manual for card removal/replacement procedures.

   Table 3-1 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.
2. If the fan unit is working properly, employ additional cooling methods to the card reporting a high-operating temperature.
3. This Critical 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, ET-IPSM, E5-TSM) EPM-B based card (E5-ATM-B, E5-ENET-B, E5-MCPM-B), or E5-SM8G-B card goes below the critical temperature threshold.
