Electrical Safety
The static discharged by human bodies can damage static-sensitive components on the boards.
When installing and maintaining the equipment, observe appropriate electrostatic safety precautions
to prevent personnel injuries or device damage.
When operating a device in an electrostatic sensitive area, you must take electrostatic-discharge
(ESD)-preventive measures. These include wearing ESD-preventive gloves, an ESD-preventive wrist
strap, and ESD-preventive clothes to avoid personnel injury or device damage.
To prevent damage to the device, pay attention to the following during operations:
• Do not touch devices with bare hands because ESD from the human body may damage the
electrostatically sensitive elements on a board.
• When dealing with the server or any of the internal components, wear an ESD-preventive wrist
strap, ESD-preventive gloves, and ESD-preventive suit.
About the Veritas 2U12 Storage Shelf I/O modules
The rear panel of the Veritas 2U12 Storage Shelf contains two I/O modules. These modules are
located between the Power Cooling Modules (PCM). The two I/O modules slide into the rear of the
shelf, with I/O module 0 above I/O module 1. The storage shelf can run with only one functioning I/O
module. If both I/O modules are faulty the storage shelf must be turned off.
The following figure shows the locations of the I/O modules and the locations of the status LEDs.
