The QX-S5524GT-4X2Q and QX-S5548GT-4X2Q are to load an expansion interface card
into the rear, and it's possible to mount 2 QSFP+ ports. You can plug the QSFP+
transceiver modules in Table 10-8. QSFP+ cable is inserted in QSFP+ port as need. A
connection shows a possible QSFP+ cable on the Table 10-9 in 40Gbps SFP+ transceiver
module.
QSFP+ cable is indicated on Figure 10-5. An indicated 40G QSFP+/10G*4 SFP+ copper
cable can also be used for Figure 10-3.
