Description

The EX4550 is a 1U Layer 3 managed 10GbE switch with 32 fixed 1/10GbE SFP+ ports, designed for data centre top-of-rack and aggregation deployments. This variant uses a 650W DC power supply and AFO (back-to-front) airflow, making it suited to -48V DC environments and hot-aisle/cold-aisle layouts with port-side exhaust. It runs Junos OS and supports Virtual Chassis, with two expansion module slots for additional 10G or 40G connectivity.

FAQs

Q: What power supply does the EX4550-32F-DC-AFO use?
A: It ships with a 650W DC power supply operating from -48V DC. A second power supply can be added for 1+1 redundancy, and the PSUs are hot-swappable.

Q: What does AFO airflow mean on this switch?
A: AFO is back-to-front airflow, with air exhausting out the front (port) side of the chassis. It suits racks where the ports face the hot aisle.

Q: Can I add 40G or 10GBASE-T ports to this switch?
A: Yes. The two expansion module slots accept optional 8-port SFP+, 8-port 10GBASE-T, 2-port 40GbE QSFP+ or 128Gbps Virtual Chassis modules.

Q: Does this switch support PoE?
A: No. The 32 fixed SFP+ ports are non-PoE, as the switch is intended for data centre aggregation and top-of-rack use.

Q: Can multiple EX4550 switches be managed as one device?
A: Yes. Virtual Chassis allows up to 10 members to be managed as a single logical switch, with redundant Routing Engines and GRES.
