TROUBLESHOOTING PLUG-INS

During device discoveries, HP Web Jetadmin attempts to determine the model name of a device.

HP Web Jetadmin then maps the model name to the appropriate device plug-in (either discreet or UPI)

to display a proper bitmap and offer the desired amount of configuration items. Typically the

interrogation of the model name involves SNMP. However, for HP FutureSmart devices, HP Web

Jetadmin might use Web Services (WS*). This means that WS Discovery must be enabled on

HP FutureSmart devices in order for HP Web Jetadmin to use the appropriate device plug-ins.

If HP Web Jetadmin either fails to map a device to the correct plug-in or does not contain a matching

plug-in (such as with discreet plug-ins), only very limited support is provided through a generic plug-in.

For example, on an HP FutureSmart device, if HP Web Jetadmin fails to map it to the correct plug-in,

only generic support that uses SNMP to interrogate the device is available. Since very few items are

defined to use SNMP for HP FutureSmart devices in HP Web Jetadmin, very little information is

provided.

Notice that the device image is that of a very old HP LaserJet II model, the front panel display claims

<Not Supported>, and only the Tray gauges are present because they are defined to use SNMP. The

Config tab offers very few configuration categories. This is a sure sign of generic support. For some

reason HP Web Jetadmin could not match the model name to the correct plug-in. This result might be

credentials related or it might be a newer device and an older version of HP Web Jetadmin that does

not have a discreet plug-in. In the case of UPIs, if the device was initially discovered with an older

version of HP Web Jetadmin that did not have a UPI and HP Web Jetadmin was subsequently

upgraded, the older plug-in is still being used.

When this scenario occurs, perform the following steps to attempt to force HP Web Jetadmin to use

the correct device plug-in:

1. Right-click the device in the device list, and select Refresh Selection.
