Required Tools and Safety Items

You need the following tools to install a line module:

•A Phillips screwdriver

•An ESD (electrostatic discharge) wrist strap

Protecting Modules and Slots

To protect the modules and slots, observe the following guidelines when installing modules:

Caution: When handling modules, use an antistatic wrist strap connected to the ERX system’s ESD grounding jack. This action helps to protect the module from damage by electrostatic discharge.
