Resetting a BSC Board

This describes how to reset BSC boards, the Central Process Unit (CPU) of the GXPUM/GXPUT, and the Digital Signal Processing (DSP) of the GDPUC/GDPUX/GDPUP. Only the ADMIN users, administrators, and custom users with related authorities can perform this operation.

Prerequisites

Context

CAUTION:

• Be careful to reset a BSC board if the standby board of the BSC board is not in position or faulty. Otherwise, the services the BSC board carries may be disrupted.
• Resetting a board may affect the existing services, so reset the board when the traffic volume is low, for example, in the early morning.

• Resetting a board

  To complete the software loading and software upgrade of a board, you must reset the board. When a board is reset, its program files and data files are reloaded.

  If the standby board is in position and works properly, resetting the active board will trigger the board switchover before the reset.

  The resetting of the active GSCU leads to the reset of the entire subrack, if the standby GSCU is not installed or faulty.

• Resetting a CPU

  Each GXPUM and GXPUT has four CPUs numbered 0 to 3; each other boards has one CPU. If the CPU 0 of the GXPUC or GXPUM is reset, the entire GXPUC or GXPUM will be reset.

• Resetting a DSP unit

  Each GDPUC/GDPUX/GDPUP has 22 DSP units numbered from 0 to 21. These DSP units can be reset individually.

Procedure

• Through GUI
  1. Resetting a board
     1. On the LMT, choose BSC Maintenance > Maintain Device > Reset BSC Board.
     2. On the dialog box shown in Figure 1, set parameters in the Board Location area, and then click Reset. A confirmation dialog box is displayed.
     3. Click Yes. A dialog box is displayed, as shown in Figure 1.

  2. Resetting the CPU/DSP.
     1. In the dialog box as shown in Figure 1, click the Reset CPU/DSP tab page.
     2. On the dialog box shown in Figure 2, set parameters in the Board Location area, and then click Reset. A confirmation dialog box is displayed.
        NOTE:

        The Subrack No. and Slot No. in the Board Location area decide the board whose CPU/DSP is to be reset. For the GXPUM or GXPUT, the CPU is to be reset. For the GDPUC/GDPUX/GDPUP, the DSP is to be reset. This topic takes resetting the CPU on the GXPUM as an example.

     3. Click Yes. A dialog box is displayed, as shown in Figure 2.

• Through MML
  1. On the Local Maintenance Terminal, run the following commands to reset the BSC boards, CPUs on the GXPUM/GXPUT, and DSP on the GDPUC/GDPUX/GDPUP.
     • Run the RST BRD command to reset BSC boards.
     • Run the RST CPU command to reset CPUs on the GXPUM/GXPUT or DSP on the GDPUC/GDPUX/GDPUP.
