5058-030 Security Reset Jumper Previous 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: 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. Remove the small yellow jumper that covers a pair of the jumper's pins. Next Go Back 4. Replace the small yellow jumper so that it covers the pins adjacent to its original position. 5. Replace and secure the Kensington lock on the card cage (if installed). 6. Power the device on. Note: The movement of the small yellow jumper from position A to position B triggers the reset, not the specific positions. When the device is powered on, it labels the current position of the small yellow jumper (let's say position A) as the "home " position. If, at the next POR, the device detects that the small yellow jumper has moved from its previous "home " position (position A) to the " other " position (position B), then it performs a jumper reset. After performing the reset, the device also relabels the " other " position (position B) as the " home " position (now position A is the "other " location). Note: The admin's security settings are lost when the RIP card is replaced. Secure settings are those that are configured under the Settings->Security->Edit Security Setups menu. These are all the PINs, Passwords, and other Building Blocks and Security Templates that define the device's protection of functions and menus. In other words, if the customer is using LDAP to authenticate users to use the Copy function, then after the RIP card is replaced, the device will no longer have that LDAP configuration or the Copy function protected.
