The E4G-200 router has an integrated DC power supply with dual feeds on the front panel. Power feed
A can be connected to one power source and power feed B can be connected to a different power
source to provide protection should either source of power fail. The power supply is not field-
replaceable.
The back panel of the E4G-200 router provides an alternate attachment point for the grounding lug.
Status LEDs on the E4G-200 router are described in

E4G-200 Clock (CLK) Module
An optional clock module for the E4G-200 router provides timing. Timing is based on either:
•
ITU-T Synchronous Ethernet (SyncE) protocol
•
Precision Time Protocol based on the IEEE specification 1588v2
The clock module has four mini-BNC connectors providing Sync In/Sync Out timing interfaces and an
RJ-45 connector that provides an RS-422 BITS-IN interface. Clock modules can be installed or removed
without powering down the router, although a system reboot is required to initialize the module.
