Removing a PC Blade
To remove a blade, do the following:
1. Lower the front bezel on the chassis by depressing the latches on each side.
2. Power down the blade (if required) and pull gently on the handle until it slides out.
Be sure to support both ends of the blade when you remove it completely from the
chassis.
CAUTION: Some surfaces on the blade may be hot, especially when the
blade has been powered on. Remove and handle the blade with care.
Never leave a PC blade unprotected when not in use. It should either be in the chassis
or in its storage box. Dust, dirt, and other debris can cause problems so keep the
boards clean by keeping them installed or in their storage box.
Locking out Mass Storage Devices
When using ClearCube's C/Ports, you have an additional feature that provides
increased levels of security. The R Series PC blades offer a unique Mass Storage
Lockout (MSL) security feature that disables the use of any USB mass storage device
connected to the C/Port 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, Sentral 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 Figure 32 and Figure 33 for the jumper locations by blade model number. The
default position for the jumper connects pins 2 and 3 (USB mass storage devices
will 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
Sentral software.
