•8 QSFP28 ports (10/25/40/50/100GbE speed)
•1 Management port
•1 Console port
•1 USB port
The chassis has 48 SFP28 and 8 QSFP28 ports. Each of these ports uses an optical
transceiver, active optical cables, or direct-attached cable to connect the SFP28 or
QSFP28 port to servers and other Ethernet switches. For more information on obtaining
the appropriate SFP28 or QSFP28 modules, refer to “Supported Cables and Transceivers”.
One management port enables you to manage the switch operation using an RJ-45
Ethernet cable.
One console port enables you to perform the initial configuration by connecting to a
PC with the RJ-45 to DB-9 serial adapter cable.
One USB port provides the flexibility and possibility to install switch runtime image
or configuration.
