Board registration failure troubleshooting

15



  1. Check whether the board is installed properly.


    Run the display device command to check whether the Online field is Present. If not, the board is not installed properly. Reinstall the board or install the board into another slot.



  2. Check whether the board is compatible with the device version.


    Run the display elabel command to check the BOM field of the board. You can determine whether the board is compatible with the device version based on the value of the BOM field. If the board is compatible with the device version, upgrade the device version.


  3. If the fault persists, contact Huawei technical support personnel.

Troubleshoot call failures
If an intra-office call fails, perform the following steps: Step 1 Check whether the corresponding intra-office prefix is configured. For example, if the called number is 4000, at least one of prefixes 4, 40, 400, and 4000 with the call attribute being intra-office is configured. Step 2 Check whether the called number is registered. Step 3 Check whether call forwarding unconditional (CFU) is configured for the called number and whether the forward-to number is unreachable. Check whether the do not disturb (DND) is configured for the called number. Step 4 Check whether the address from which the calling number initiates the call is different from the registration address. Step 5 Run the show license command to check whether a temporary license is used and whether this license has expired. If an inter-office call fails, perform the following steps: Step 1 Run the show tkc office no x command to check the interconnection trunk status. The variable x indicates the office route number of the trunk. The trunk is functional if its status is displayed as IDLE. Step 2 Check whether the prefix is correctly associated with other relevant parameters. When you configure the prefix, you also need to configure the corresponding office route selection code, which needs to be associated with an office route. The office route needs to be associated with a trunk. Step 3 Check whether the calling number has the corresponding call rights. Step 4 Check whether the calling number is correct. Ensure that the calling number is the number allocated by the carrier in the case of connection to the carrier network. Step 5 Capture signaling messages and check whether the local end or peer end disconnects the call. If the local end disconnects the call, check the call disconnection time and the call setup request time. Maybe the peer end does not respond to the call setup request within the required time, causing call disconnection upon timeout. For the call disconnection causes, rectify the fault according to actual situations.

Revelations of troubleshooting-SSH login failure
If logging to the SSH server through STelnet fails, check the following configuration: 1. Check whether the SSH service is enabled on the SSH server. 2. Check whether the access protocol is correctly configured in the VTY user interface view. 3. Check whether an RSA public key is configured on the SSH server. 4. Check whether an SSH user is configured on the SSH server. 5. Check whether the number of login users on the SSH server reaches the upper limit. 6. Check whether an ACL is bound to the VTY user interface of the SSH server. 7. Check the SSH version on the SSH client and server. 8. Check whether first-time authentication is enabled on the SSH client.

Why a PoE card fails to be registered on S series switches
The ES0D0G48VA00 card is the PoE card for the S12700 and S7700, and the LE0DG48VEA00 card is the PoE card for the S9300. Possible causes of a PoE card registration failure are as follows: No PoE power module is installed in the PoE power slot of the switch. The PoE power module is not powered on. The dual in-line memory module (DIMM) is faulty. For the handling methods, see "Fault Locating Guide - Card Registration Failure" in Huawei S Series Campus Switches Maintenance Guide.
