2.7.175 INVMACADR
• There is a read error occurring on one of the redundant TCC2/TCC2Ps that read the address from
the AIP; these cards read the address independently and could therefore each read different address
values.
• An AIP component failure causes a read error.
• The ribbon cable connecting the AIP card to the backplane is bad.
Clear the INVMACADR Alarm
Step 1 Check for any outstanding alarms that were raised against the active and standby TCC2/TCC2P and
resolve them.
Step 2 If the alarm does not clear, determine whether the LCD display on the fan tray (Figure 2-2 on
page 2-125) is blank or if the text is garbled. If so, proceed to Step 8. If not, continue with Step 3.
Step 3 At the earliest maintenance window, reset the standby TCC2/TCC2P:
Note The reset requires approximately five minutes. Do not perform any other step until the reset is
complete.
a. Log into a node on the network. If you are already logged in, continue with Step b.
b. Identify the active TCC2/TCC2P.
A green ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates a standby card.
c. Right-click the standby TCC2/TCC2P in CTC.
d. Choose Reset Card from the shortcut menu.
e. Click Yes in the Are You Sure dialog box.
The card resets, the FAIL LED blinks on the physical card, and connection to the node is lost. CTC
switches to network view.
f. Verify that the reset is complete and error-free, and that no new related alarms appear in CTC. A
green ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates a standby card.
g. Double-click the node and ensure that the reset TCC2/TCC2P is still in standby mode and that the
other TCC2/TCC2P is active.
A green ACT/SBY LED indicates an active card. An amber ACT/SBY LED indicates a standby card.
h. Ensure that no new alarms associated with this reset appear in the CTC Alarms window.
If the standby TCC2/TCC2P fails to boot into standby mode and reloads continuously, the AIP is
probably defective. In this case, the standby TCC2/TCC2P is unsuccessfully attempting to read the
EEPROM located on the AIP. The TCC2/TCC2P reloads until it reads the EEPROM. Proceed to Step 8.
Step 4 If the standby TCC2/TCC2P rebooted successfully into standby mode, complete the “Remove and
Reinsert (Reseat) the Standby TCC2/TCC2P Card” procedure on page 2-272.
Resetting the active TCC2/TCC2P causes the standby TCC2/TCC2P to become active. The standby
TCC2/TCC2P keeps a copy of the chassis MAC address. If its stored MAC address is valid, the alarm
should clear.
Step 5 After the reset, note whether or not the INVMACADR alarm has cleared or is still present.
Step 6 Complete the “Reset an Active TCC2/TCC2P Card and Activate the Standby Card” procedure on
page 2-270 again to place the standby TCC2/TCC2P back into active mode.
