3.
Calculate the total power consumption, and make sure your power supply can provide enough
power. For more information, see "Power supplies."
4.
Verify that the service module is fully seated. You can remove the service module, install it
again, and press the ejector levers inward until the ejector levers touch the panel tightly.
5.
If the router has empty service module slots, install the service module in an empty service
module slot, and verify that the service module is operating correctly.
6.
If the failure persists, contact the local agents or technical support engineers.
Troubleshooting interfaces
The interfaces provided by MPUs and service modules all have associated LEDs. When an interface
connected to the network is operating correctly, its LED is on.
NOTE:
A management Ethernet interface or XFP interface each has two LEDs, LINK and ACT. The LED
mentioned in this section for such an interface refers to the LINK LED. Each interface of any other
type has only one LED.
If the LED of an interface connected to the network is off, the interface or the connecting cable might
fail. To troubleshoot the interface:
1.
Verify that the MPU or service module where the interface resides is operating correctly. For
more information, see "
Troubleshooting the service modules
."
2.
Verify the cable connection of the interface. For how to correctly connect the cable to a copper
port with an RJ-45 connector or to a fiber port, see "Connecting your router to the network
through twisted pair cables."
3.
Verify that the cable is not broken. Use the cable to connect two interfaces of the same type that
are operating correctly. If the LEDs of the two interfaces are on, the cable is normal. Otherwise,
the cable is broken. Use a compliant cable to connect the interface. For more information about
the compliant cables, see "Appendix E Cables."
4.
If the interface uses a transceiver module, verify that the current transceiver module is not faulty
by replacing a transceiver module. If the LED of the interface is on after a replacement, the
previous transceiver module is faulty.
5.
Verify that the speed and duplex settings of the interfaces for a link are the same. Make sure
two interfaces can collaborate correctly.
6.
If the failure persists, contact the local agents or technical support engineers.
NOTE:
After an interface fails, if the router has an idle interface of the same type, you can connect the cable
to the idle interface.
Troubleshooting CF cards
The MPU provides a CFS LED. When the CF card is operating correctly, the CFS LED is on.
If the CFS LED is off, the CFD card fails.
To troubleshoot the CF card:
1.
Verify that the MPU is operating correctly. For more information, see "
."
2.
If the CF card fails because you execute the
umount
command, you can execute the
mount
cfa0:
command in user view to re-mount the CF card.
