Chapter 2 Alarm Troubleshooting
Alarm Procedures
Step 9 If the reset card or replaced card has not rebooted successfully, or the alarm has not cleared, call TAC
(1-800-553-2447). If the TAC technician tells you to reseat the card, complete the “Remove and Reinsert
(Reseat) the Standby XTC” procedure on page 3-3. If the TAC technician tells you to remove the card
and reinstall a new one, follow the “Physically Replace a Card” procedure on page 2-130.
Note When replacing a card with an identical type of card, no additional CTC provisioning is
required.
2.6.39 CONTBUS-IO-B
• Major (MJ), Non-Service Affecting (NSA)
An XTC B to Shelf Slot Communication Failure alarm occurs when the XTC card in Slot 6 (XTC B) has
lost communication with another card in the shelf The other card is identified by the Object column in
the CTC alarm window..
The CONTBUS-IO-B alarm can appear briefly when the ONS 15327 switches to the standby XTC card.
In the case of an XTC protection switch, the alarm clears after the other cards establish communication
with the new active XTC card. If the alarm persists, the problem is with the physical path of
communication from the XTC to the reporting card. The physical path of communication includes the
XTC card, the other card, and the backplane.
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 CONTBUS-IO-B Alarm
Step 1 Ensure that the reporting card is physically present in the shelf. Record the card type. Click the
Inventory tab to reveal the provisioned type.
If the actual card type and the provisioned card type do not match, see the “MEA (EQPT)” section on
page 2-90.
Step 2 If the alarm object is any single card slot other then the standby XTC card in Slot 5, perform a CTC reset
of the card. Complete the “Reset a Traffic Card in CTC” procedure on page 2-129.
Step 3 When you reinsert the high-speed card, verify the following LED behavior:
• The FAIL LED blinks for approximately 30 seconds.
• All LEDs blink once and turn off.
• The ACT/STBY LED is green (active).
Step 4 If the alarm object is the standby XTC in Slot 5, perform a soft reset of this card:
a. Right-click the Slot 5 XTC card.
b. Choose Reset Card from the shortcut menu.
c. Click Yes in the confirmation dialog box. Wait ten minutes to verify that the card you reset
completely reboots and becomes the standby card.
