NOTE:
• You can use a QSFP-40G-SR4-MM850 or QSFP-40G-CSR4-MM850 transceiver module to
connect a QSFP+ port to four SFP+ ports. The QSFP+ transceiver module and SFP+ transceive
r
modules to be connected must be the same in specifications, including central wavelength and
fiber type.
• Interface numbered 31 on the S6850-56HF and S9850-32H switches cannot be split into four
interfaces.
• When the LSWM18CQ or LSWM18CQMSEC interface module is installed in slot 2 on the
S9850-4C switch, interface numbered 7 on the interface module cannot be split into four
interfaces.
• When the LSWM124TG2H interface module is installed in slot 2 on the S9850-4C switch, the
interface numbered 25 on the interface module cannot be split into four interfaces.
