# Freestanding Installation

When installing the system on a table top or in any other freestanding mode, be sure to leave enough space around the system for adequate ventilation. Position the router with easy access to the connections that it needs for power, local communications, and remote communications.

See Installation Guidelines and Requirements, and System Specifications, for more information.

| Warning: Two people are required to lift an E Series router.

| Caution: To prevent electrostatic damage to the system and its components, make sure persons handling the router wear an antistatic device.

Connectors are located on the I/O modules and the power input module. These modules are installed from the rear of the router. (See Figure 14.) See Cabling ERX Routers for cabling installation procedures.
