specified with the rest, where the msgSlot field is the slot, msgPort is the port on the slot, while
the msgInstance field is used when further differentiation is necessary.
The other fields correspond to the fields in the GUI: the msgSeverity field to Level, the
msgSourceName field to Application, the msgText field to Error Code, and the
msgGenerationTime field to Set.
For more information on using the SNMP agent, refer to the SNMP Integration
Guide.
11.3 SOAP XML Interface
The SOAP XML interface can be used for external control and monitoring of the unit. For more
information on the SOAP XML interface, refer to the Sencore SOAP XML API document.
12 Maintenance
This chapter describes how to perform maintenance tasks such as software upgrades,
replacing faulty modules, etc.
12.1 Software Upgrades
Software can be uploaded to the unit remotely using the Maintenance Center (MC) available on
port 8088 of the unit, ie http://<ip_addr>:8088/. Refer to the Upgrade Guide for details.
Required software upgrades for the units will be provided together with instructions by
Sencore’s support department.
For more details on the upgrade procedure, please refer to the Upgrade Guide document.
12.2 Hot-Swapping
The platform supports module hot-swapping, i.e. the different modules – power supply, fan,
input, or switch – can be replaced when the head-end is in operation, without shutting it down.
In other words, removing a module and replacing it with a new one will not damage the module.
The effects of hot-swapping a module are explained in further detail in the following sections.
12.2.1 Performing a Hot-Swap
To remove a module, first loosen the screws on the top and bottom (one screw is located in the
ejector). Next, press the white button inside the module ejector and push the ejector down. The
module is now released from the chassis.
To insert a new module into the chassis, it is important to align the module’s edges with the
module-guides in the chassis. Ensure that the jack on the module is in the open position as
illustrated in the figure below. Slide the module into the unit on the module-guides until the jack
touches the chassis. Move the jack upwards. This will insert the module all the way into the unit.
