The ExtremeSwitching VSP 7400 Series switches offer a versatile and efficient core/aggregation switching functionality for campus environments. The VSP 7400 Series switches run the VOSS operating platform.
VSP 7400 Series switches include the following base models:

An SFP28 based 10 Gb or 25 Gb port.
A QSFP28 based 100 Gb port that can, with appropriate cabling, be partitioned/channelized into four 25 Gb data lanes.
A QSFP+ based 40 Gb port that can, with appropriate cabling, be partitioned/channelized into four 10 Gb data lanes.
For details about the port partitioning/channelizing options that are available on VSP 7400 Series switches, see Partitioning/Channelizing Switch Ports.
A serial console port on the front panel allows you to connect a terminal and perform local management. An Ethernet management port can be used to connect the system to a parallel management network for administration. Alternatively, you can use an Ethernet cable to connect this port directly to a laptop to view and locally manage the switch configuration. The Ethernet management port supports 10/100/1000 Mbps speeds.
A USB port can be used for network management or for attaching a removable memory module.
Switch cooling is provided by field-replaceable fan modules. Fan modules are available in two different models that direct the airflow either from front to back or from back to front. All installed fan modules must be of the same model, so that they all direct the airflow in the same direction.
Two power supply bays accommodate 750 W AC or DC power supplies. Supported power supply configurations include two AC, two DC, or one AC and one DC power supplies. configurations include Power supplies have integrated cooling fans that operate independently of the switch fans. Like the fan modules, the power supplies are available in models with either front-to-back or back-to-front cooling airflow.
Both front-to-back and back-to-front airflow options are available. However, on any given VSP 7400 Series switch, air must flow in the same direction for all installed fan modules and power supplies.
Channelization allows you to partition QSFP28 ports into four logical ports. In 100-Gigabit mode, each port can be partitioned into four logical 25-gigabit ports. In 40-gigabit mode, each port can be partitioned into four 10-gigabit ports. Channelization can be enabled on all ports of VSP 7432CQ, except port 28. Channelization is not supported on VSP 7400-48Y QSFP28 ports.
Logical port numbers are represented as slot/port/sub-port in the CLI when channelization is enabled. For example, when channelization is enabled on port 8 of VSP 7432CQ, the four logical ports are represented as 1/8/1, 1/8/2, 1/8/3 and 1/8/4 in the CLI.
The VSP 7400 Series has a PHYless design. The benefits of a PHYless design are lower powerconsumption and lower latency. However, due to the PHYless design, the following transceivers that require electronic dispersion compensation (EDC) for proper operation are not supported:
AA1403017-E6: 1-port 10GBASE-LRM SFP+
AA1403016-E6: 1-port 10GBase-ZR/ZW SFP+
The AA1403165 10GBASE-ZR CWDM DDI SFP+ transceiver can be substituted forAA1403016-E6 10GBASE-ZR/ZW SFP+.
