Featuring up to 48 wire-speed 1GbE or 10GbE small form-factor pluggable transceiver (SFP/SFP+) or 100M/1GBASE-T/10GBASE-T ports in a compact one rack unit (1 U) platform, the Juniper Networks® EX4550 Ethernet Switch delivers 480 Gbps of Layer 2 and Layer 3 connectivity to networked devices such as servers and other switches. Two versions of the EX4550 base switch are available: the EX4550-32F, a fiber-based version that provides 32 fixed 10GbE SFP/SFP+ pluggable ports; and the EX4550-32T, a copper-based version that supports 32 fixed 100M/1GBASE-T/10GBASE-T ports. Both versions feature two expansion slots, one in front and one in back, that can accommodate one of four optional expansion modules, providing tremendous configuration and deployment flexibility for campus and data center access and aggregation networks. The four expansion modules include: • A 128 Gbps Virtual Chassis module • An 8x10GBASE-T copper expansion module • An 8x10GBASE SFP/SFP+ fiber expansion module • A 2x40GbE QSFP+ expansion module
