EX4550 switches have a base port density of 32 fixed 10-Gigabit SFP+ or 10-Gigabit Ethernet BASE-T (10GBASE-T) ports that you can scale up to 48 ports by installing the optional expansion modules. You can configure EX4550 switches in a Virtual Chassis, or in a mixed Virtual Chassis with Juniper Networks EX4200 Ethernet Switches or Juniper Networks EX4500 Ethernet Switches or both, in a total of up to 10 members. You can expand the number of ports on an EX4550 switch by installing up to two optional expansion modules in the module slots on either side of the chassis. The optional modules for an EX4550 switch are: 8-port 10-Gigabit SFP+ expansion module—Provides eight ports for eight 1-gigabit small form-factor pluggable (SFP) transceivers or eight 10-gigabit small form-factor pluggable (SFP+) transceivers. You can install a total of eight SFP and SFP+ transceivers in any combination in these eight ports. 8-port 10GBASE-T expansion module—Provides eight ports for 100-Megabit Ethernet BASE-T, 1-Gigabit Ethernet BASE-T, or 10-Gigabit Ethernet BASE-T RJ-45 connectors. 2-port 40-Gigabit QSFP+ expansion module—Provides two ports for 40-gigabit quad small form-factor pluggable (QSFP+) transceivers. 128-Gigabit Virtual Chassis module—Provides two dedicated Virtual Chassis ports (VCPs) for connecting the switch in a Virtual Chassis. You can also connect Virtual Chassis members using the SFP+ network ports, SFP+ expansion module ports, 10GBASE-T network ports, 10GBASE-T expansion module ports, and QSFP+ expansion module ports configured as VCPs. Benefits of the EX4550 Switch:Compact solution—The EX4550 switch supports up to 48 10-Gigabit Ethernet ports in a 1 rack unit (1 U) chassis. Support for Virtual Chassis—EX4550 switches support Virtual Chassis technology. You can interconnect up to 10 EX4200 switches, EX4500 switches, or EX4550 switches to form a Virtual Chassis. Energy efficiency—The 10-Gigabit Ethernet fiber ports consume less than five watts and the 10-Gigabit Ethernet copper ports consume less than nine watts, thereby offering a low power solution for top-of-rack, end-of-row, and aggregation deployments.
