FAQ

How Can I Determine Whether the Card Status Is Normal?

Run the display device [ slot slot-id ] command to view component information and device status. When the Register field displays Registered and the Status field displays Normal, the card status is normal.
NOTE:

The status indicates the hardware management status excluding the service running status.

Why Does the Standby MPU Fail to Register?

On a chassis with two MPUs, if one MPU has started normally but the other MPU cannot register and remains in Unregistered state for a long period of time, the MPU that has started is the active MPU, and the other MPU that cannot register is the standby MPU. You can perform the following operations to check why the standby MPU cannot register:
  1. Check whether the standby MPU is properly installed.
  2. Check whether the standby and active MPUs are the same hardware model and have the same type of subcards installed or do not have any subcard installed.
  3. Connect to the standby MPU through the console port to check whether the standby MPU uses the same system software as the active MPU. If not, replace the system software of the standby MPU to the one running on the active MPU.
  4. Run the display reset-reason command to check why the card restarts. For details, see "A Card Resets Unexpectedly" in the Troubleshooting - Hardware Troubleshooting.
  5. Collect log information, alarm information, and configuration information, and then contact technical support personnel to confirm whether a hardware fault occurs.

What Does PowerOff Mean and Why Is PowerOff Displayed in an LPU's Status Information?

If the LPU status displays PowerOff, the LPU is powered off. Perform the following operations to check why the LPU is powered off:
  1. Check whether the power off slot slot-id command has been executed to power off the LPU according to the current environment and planning requirements. If so, no action is required. If not, run the power on slot slot-id command to power on the LPU.
  2. If the LPU fails to be powered on, run the display power system command to view the system power and card power. According to the information, you can determine whether the LPU cannot be powered on because of insufficient power. If the remaining system power is insufficient, add a system power module to increase the system power.
  3. Check whether the LPU matches the running system version. For the mapping between LPUs and software versions, see "Version Mapping" of the specific card in the Hardware Description - Cards.
  4. Run the display reset-reason command to check the reason why the LPU is powered off. For details, see "A Card Resets Unexpectedly" in the Troubleshooting - Hardware Troubleshooting.
  5. If you still cannot determine why the LPU is powered off, collect log information, alarm information, and configuration information, and then contact technical support personnel to confirm whether a hardware fault occurs.

What Does Unregistered Mean and Why Is Unregistered Displayed in an LPU's Status Information?

If the power-on status of an LPU is PowerOn but the registration status is Unregistered, the LPU is starting but has not registered successfully. In the beginning of a system upgrade or system downgrade, or when an LPU is just installed or powered on, it may take a long time for the LPU to register because of version update. This is a normal situation, and the LPU will register successfully. If the LPU cannot register for a long time (more than 30 minutes for example), the LPU cannot start normally. If a stably running LPU restarts unexpectedly when no manual operations, such as running a restart command line, upgrading or downgrading the system, are performed, the LPU status will become Unregistered.

Run the display reset-reason command to view the reason why the LPU restarts. For details, see "A Card Resets Unexpectedly" in the Troubleshooting - Hardware Troubleshooting.

What Does Offline Mean and Why Is Offline Displayed in an SFU's Status Information?

The Offline state can be displayed only for switch fabric units (SFUs) on an S12700 switch. Before removing an SFU from the chassis, you must set the SFU to the Offline state. Otherwise, data forwarding and services are affected. The Offline state indicates that an SFU has been separated from the system and can be removed from the chassis. When an SFU is triggered Offline and the OFL indicator is steady red, the SFU state changes from Present to Offline.

An SFU is triggered Offline in either of the following conditions:
  • The SFU is not used for cluster connection and is not the only usable SFU. A user holds down the OFL button on the SFU for 6 seconds to trigger it Offline.
  • The SFU is used for cluster connection but is not the only SFU used for cluster setup. A user holds down the OFL button on the SFU for 6 seconds to trigger it Offline.
