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. 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.
Partitioning/Channelizing Switch Ports
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.
VSP 7400 Series Operational Notes
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+.
VSP 7432CQ Features
The front panel of the VSP 7432CQ switch includes:
•
32 100-gigabit Ethernet ports capable of supporting passive copper QSFP28/QSFP+ and active fiber
QSFP28/ QSFP+. With a few exceptions, noted below, these ports are configurable for 100 Gb, 40
Gb, 4x25 Gb, and 4x10 Gb modes. For information about QSFP28 and QSFP+ optical modules, see
the
Extreme Networks Pluggable Transceivers Installation Guide
.
Note
Exception: Physical port 28 cannot be partitioned.
