For more information about the QSFP+ transceiver module and QSFP+ DAC cables, see HP
Comware-Based Devices Transceiver Modules User Guide.
NOTE:
• HP recommends that you use QSFP+ transceiver modules or QSFP+ DAC cables for the QSFP+ ports on
the switch. The HP QSFP+ transceiver modules and QSFP+ DAC cables are subject to chan
g
e over time.
For the most up-to-date list of HP QSFP+ transceiver modules and QSFP+ DAC cables, contact your HP
sales representative or technical support engineer.
• You can use an HP X140 40G QSFP+ MPO SR4 transceiver (JG325B) or HP X140 40G QSFP+ MPO
MM 850nm CSR4 300m transceiver (JG709A) to connect a QSFP+ port to four SFP+ ports. The QSFP+
transceiver module and SFP+ transceiver modules to be connected must be the same in specifications,
including central wavelength and fiber type.
