third-party optical module or cable and, if required, replace it with an equivalent
Juniper-qualified component.
Use of third-party optical modules with high-power consumption (for example,
coherent ZR or ZR+) can potentially 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
optical 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 EX9251 switches support digital optical monitoring
(DOM). You can view the diagnostic details for these transceivers by issuing the operational mode CLI
