2.6.127 MEA (EQPT)
• Critical (CR), Service Affecting (SA)
The Missing Equipment Attributes (MEA) alarm for equipment is reported against a card slot when the
physical card inserted into a slot does not match the card type that is provisioned for that slot in CTC.
Removing the incompatible cards clears the alarm.
Caution Always use the supplied electrostatic discharge wristband when working with a powered ONS 15327.
Plug the wristband cable into the ESD jack located between the top high-speed and XTC slots.
Procedure: Clear the MEA (EQPT) Alarm
Step 1 Physically verify the type of card that sits in the slot reported in the Alarms window MEA alarm Object
column.
Step 2 In CTC, click the Inventory tab to reveal the provisioned card type.
Step 3 If you prefer the card type depicted by CTC, complete the “Physically Replace a Card” procedure on
page 2-130 for the reporting card.
Note When replacing a card with an identical type of card, no additional CTC provisioning is
required.
