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.
  4. If this procedure did not clear the fault, contact My Oracle Support (MOS).
