ALERT
!
ALERT! To avoid electrostatic discharge, always
wear a grounding strap plugged into the ESD jack
when handling any MIX 56 components.
Front Panel
Each MIX 56 chassis houses two independent systems, System 1 and Sys-
tem 2. The front of each system is equipped identically (with the exception
of one electrostatic discharge (ESD) jack per chassis), and either system
can be used as a DSX only, as a nonredundant multiplexer, or as a redun-
dant multiplexer.
Front Panel Definitions
ACO/LMP Button: One per system. When pressed and released, it turns
off external alarms for a time period specified in the system settings screen
of the Craft interface or through SNMP. When pressed and held for three
seconds, it tests the LEDs on the LED panel and the M13 cards by chang-
ing the panel LEDs to yellow (except Critical and Major, which turn to red)
and changing the card LEDs to orange. Testing the LEDs also resets the
ACO timer.
DSX Jack: 28 per system. Used for patching and monitoring DS1 signals.
