Repair and Replacement

This chapter describes periodic maintenance procedures, troubleshooting procedures, and the replacement of major parts for the MGX 8220.

Caution For protection against shock hazard, verify both power cords are disconnected before servicing the unit.

Caution Vergewissern sie sich, däss beide Netzkäbel vom Gerät getrennt sind, bevor Sie mit den Wärtungsärbeiten beginnen.

Caution Pour iviten tout danger, dibrancher les deux cordons d’alimentation avant toute intervention de maintenance sur cet equipement.

Preventive Maintenance

Most monitoring and maintenance of the MGX 8220 shelf is done using the operating system software. Preventive maintenance of the MGX 8220 shelf hardware is minimal.

1.Periodically check the node supply voltage and internal cabinet temperature. The temperature should not exceed 50° C.

2.Periodically check the event log with the dsplog command.

3.Periodically check the network alarm status with the dspalms command.

4.Ensure that the cooling unit intake grills and the exhaust plenum are clear.

Troubleshooting the MGX 8220 Shelf

This section describes basic troubleshooting steps to be taken for some of the more obvious node failures. (See Table 8-1.) This is not an exhaustive set of procedures, and does not take into account any of the diagnostic or network tools available to troubleshoot the MGX 8220 shelf. See Chapter 5, “Service Configuration,” for information on commands and command usage.
