NOTE: Werecommend that you use only Juniper Networks SFP+ directattach
cables with your EX Series switches.
The cables are hot-removable and hot-insertable: You can remove and replace them
without powering off the switch or disrupting switch functions. A cable comprises a
low-voltage cable assembly that connects directly into two SFP+ ports, one at each end
of the cable. The cables use high-performance integrated duplex serial data links for
bidirectional communication and are designed for data rates up to 10 Gbps.
Table 17 on page 36 lists the software support for SFP+ direct attach cables by software
release.
