C/Port Installation

Locking out Mass Storage Devices

An additional feature provides increased levels of security with C/Ports. The R Series PC

blades offer a unique Mass Storage Lockout (MSL) security feature that disables the use of

any USB mass storage device at the desktop (e.g., key drives, floppy drives, CD-ROM drives,

etc.). The default factory setting does not enable this security feature – thus in the default

mode, any USB device, including mass storage devices connected to the C/Port, will be

recognized by the operating system. However, Switch Manager allows setting MSL in

software to lock out the use of storage devices.

To enable MSL in hardware, a jumper on the PC blade needs to be moved from the default

position to the adjacent position. You will need a set of needle-nose pliers to access the MSL

jumper. See

on page 19 for the jumper locations by

blade model number. The default position for the jumper connects pins 2 and 3, and USB mass

storage devices function normally.

When the jumper is in the default position, you can also use a software setting to disable mass

storage devices. This software setting is accessible through the Switch Manager software.

Note: When the MSL jumper is physically set to lock out mass storage devices, the software

cannot override this.
