Switch Special Instrucons
EX2300-C You must install the EX2300-C in a restricted-access locaon and ensure that the chassis is
always properly grounded. The EX2300-C has a two-hole protecve grounding terminal
provided on the chassis. Under all circumstances, use this grounding connecon to ground
the chassis. For AC-powered systems, you must also use the grounding wire in the AC
power cord along with the two-hole grounding lug connecon. This tested system meets or
exceeds all applicable EMC regulatory requirements with the two-hole protecve
grounding terminal.

EX4200
Some early variants of EX3200 and EX4200 switches for which the Juniper Networks
model number on the label next to the protecve earthing terminal is from 750-021 xxx
through 750-030 xxx require 10-24x.25 in. screws.
