Expansion module for QFX5100 switches

The Juniper QFX-EM-4Q is an expansion module designed for the QFX5100 series. It adds four QSFP+ ports to increase port density in data networking environments. The module is hot-swappable, allowing installation or removal without interrupting switch operation. It provides a straightforward way to expand 40 Gigabit Ethernet connectivity.

Suitable for QFX5100 owners needing extra ports

This module suits administrators who need to add four 40GbE ports to a compatible QFX5100 switch using available expansion bays. It is not for users whose switches lack the required expansion slots or who require channelised port configurations. Buyers needing different port speeds or form factors should consider other options.

Four QSFP+ ports at 40 Gigabit Ethernet

Each of the four expansion slots accepts a QSFP+ transceiver for 40GBase-X optical connections. Ports operate as native 40 Gigabit Ethernet links without channelisation. The module supports hot insertion and removal for continuous operation. RoHS compliance confirms environmentally friendly manufacturing.
