EX4550, 8-Port 1/10G SFP+ Expansion Module
Part Number: EX4550-EM-8XSFP, New
You can install up to two expansion modules in an EX4550 switch—one in each of the module slots on the front panel and the rear panel of the switch.
EX4550 switches can support three different types of expansion modules—an 8-port 10-Gigabit SFP+ expansion module, an 8-port 10GBASE-T expansion module, and a 2-port 40-Gigabit QSFP+ expansion module. Expansion modules are hot-insertable and hot-removable field replaceable units (FRUs).
An 1/10G SFP+ expansion module can house up to eight 10-gigabit SFP+ transceivers or these 1-gigabit SFP transceivers or in any combination of SFP and SFP+ transceivers. You can use the ports on the expansion module to connect the switch to other devices. You can also configure these ports as Virtual Chassis ports (VCPs) and use them to connect the switch in a Virtual Chassis configuration.
