Juniper EX4400 - Connector Pinout Information

third-party opcal module or cable and, if required, replace it with an equivalent
Juniper-qualied component.
Use of third-party opcal modules with high-power consumpon (for example,
coherent ZR or ZR+) can potenally cause thermal damage to or reduce the lifespan of
the host equipment. Any damage to the host equipment due to the use of third-party
opcal modules or cables is the users’ responsibility. Juniper Networks will accept no
liability for any damage caused due to such use.
The Gigabit Ethernet transceivers installed in EX4400 switches support digital opcal monitoring
(DOM): You can view the diagnosc details for these transceivers by issuing the operaonal mode CLI
command show interfaces diagnostics optics.
NOTE: The transceivers support DOM even if they are installed in ports congured as Virtual
Chassis ports (VCPs).
