ERX 8.0.x Hardware Guide

RS-232—The port provides a serial connection for monitoring the system’s hardware configuration through a PC (running terminal emulation software) or ASCII terminal. Allows direct CLI access.

Alarm contacts—The contacts provide for remote indication of critical, major, and minor router alarms (ERX-7xx and ERX-14xx models only; currently not implemented)

External timing inputs—The inputs provide a method of ensuring that the clock timing used by the router remains synchronized with the network’s system clock. BNC connectors and wire wraps are available for ERX-7xx and ERX-14xx models only.
