Installation Instructions

VSP 8400 ports can be used with QSFP+ transceivers depending on the type of Ethernet Switch
Modules (ESM) installed. For information about ESM types for VSP 8400, see Installing the Virtual
Services Platform 8000 Series.
VSP 7200 Series switches support 40 Gbps QSFP+ transceivers on ports 2/1–2/6.
VSP 4000 switches do not support 40 Gbps QSFP+ transceivers because the VSP 4000 devices do
not have any QSFP+ ports. However, the VSP 4000 Series supports four SFP+ 10 Gigabit ends of
the breakout cable (BOC) assembly.
Selecting a QSFP+
Use a QSFP+ transceiver for 40 Gigabit per second (Gbps) Ethernet connections over optical fiber.
Alternatively, you can use a direct attach cable (QSFP+ to QSFP+ DAC) to connect ports for cable
distances of up to 5 meters.
About this task
Select the appropriate transceiver to provide the required reach.
Procedure
1. Determine the required reach.
2. Determine wavelength restrictions or requirements.
3. Use the following job aid to determine the appropriate QSFP+ transceiver or cable for your
application.
Job aid
QSFP+ transceivers are designed to support 40 Gigabit Ethernet. Different transceiver types are
available for use over different optical fiber types and for different optical reaches.
All Extreme Networks QSFP+ transceivers use LC connectors and MPO/MTP connectors to provide
precision keying and low interface losses.
To determine the appropriate QSFP+ transceiver or cable for your application, see Supported
transceiver, BOCs, and DACs information on page 16.
Installing a QSFP+ transceiver
Install a QSFP+ transceiver to provide a 40 Gigabit Ethernet interface between the device and other
network devices.
Before you begin
• Verify that the QSFP+ is the correct model for your network configuration.
• Before you install the fiber, ensure the connector is clean.
