Security Reset Jumper - Lexmark X792 Service Manual

Security reset jumper

The Security Reset Jumper is available on all high-end printer and MFP models.
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.
Note: An administrator controls how a jumper reset affects a device by configuring the jumper-related setting on
the Security Web page. 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. Alternatively, 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.
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 (for example,
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
(position A is now 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 protection of the 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 LDAP configuration and the Copy function will no longer be protected.
