4062-XXX Security Reset Jumper The Security Reset Jumper is available on all high-end printer and MFP models, including the T650, T652, T654, X652, X654, X656, and X658. It functions as described below (excerpt from the RIP Functional Spec): Security Reset Jumper Each device contains a hardware jumper with which an administrator can: • Erase all security templates, building blocks, and access controls that a user has defined (i.e. the factory default configuration); or • Force the value of each function access control to "No Security" (all security templates and building blocks are preserved but not applied to any function). Note: Note: If the "Enable Audit " setting in the Security Audit Log section of the "Security Menu " is activated, the device logs a message each time that the jumper is used. A small lock icon identifies the jumper's position on the RIP card. Also, to make it easier to separate the small yellow plastic jumper from the 3-pin connector, a looped handle is attached to the top of the small yellow jumper that covers the 3-pin connector. An administrator controls how a jumper reset affects a device by configuring the jumper-related setting on the Security Web page. Note: Administrators can discourage tampering with the jumper by securing the entire RIP card cage (of which the jumper is a part) with a Kensington lock. or, to completely negate the effects of a jumper reset, an administrator can select the "No Effect " value for the jumper-related setting on the Security Web page or in the "Security Reset Jumper " setting in the " Security Menu". To perform a jumper reset operation: 1. Power the device off. 2. Remove the Kensington lock from the card cage (if installed). 3-108 Service Manual
