Pluggable Transceivers Supported on EX4500 Switches
Uplink module ports on EX4500 switches support SFP and SFP+ transceivers. You can find the list of
transceivers supported on EX4500 switches and information about those transceivers at the
Compatibility Tool page for
NOTE: We recommend that you use only optical transceivers and optical connectors purchased
from Juniper Networks with your Juniper Networks device.
CAUTION:
third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC)
can help you diagnose the source of the problem. Your JTAC engineer might recommend
that you check the third-party optic or cable and potentially replace it with an equivalent
Juniper Networks optic or cable that is qualified for the device.
The Gigabit Ethernet SFP and SFP+ transceivers installed in EX4500 switches support digital optical
monitoring (DOM): You can view the diagnostic details for these transceivers by issuing the operational
mode CLI command show interfaces diagnostics optics.
NOTE: The transceivers support DOM even if they are installed in uplink module ports configured
as Virtual Chassis ports.
