General Safety Precautions
Before working on the equipment, be aware of standard safety practices and the hazards involved in
working with electrical circuitry to prevent accidents. Adhere to the following cautions and warnings for
safe and hazard-free installation.
Caution
Proper ESD protection is required whenever you handle Cisco equipment. Installation and
maintenance personnel should be properly grounded using grounding straps to eliminate the risk of
ESD damage to the equipment. Modules are subject to ESD damage whenever they are removed from
the chassis.
Caution
If fuses are already installed in the fuse and alarm panel, remove them. You can replace the fuses
after the system I/O module is installed. Do not power up the system while you install and connect
the system I/O module.
Static voltages as low as 30 volts can cause latent damage to circuitry on the system I/O module.
Caution
Observe all standard antistatic procedures (for example, wear a grounding strap).
This warning symbol means danger . You are in a situation that could cause bodily injury. Before
