FAQs

Q: What does the AFO suffix mean on this switch?
A: AFO denotes front-to-back airflow, where air exits at the front of the chassis. This suits racks where the port side faces the cold aisle. Confirm your rack airflow layout before ordering.

Q: Does this switch use AC or DC power?
A: This model is DC powered and includes dual DC power supplies in a 1+1 redundant arrangement, along with redundant fan modules.

Q: Can the 100G uplink ports be used at other speeds?
A: Yes. The 8 QSFP28 ports support 100GbE and 40GbE, and each can be configured as 4x25GbE using breakout cables.

Q: Does the EX4650-48Y-DC-AFO support PoE?
A: No. This model has no PoE capability, so powered devices need a separate power source.

Q: What is this switch typically used for?
A: It is aimed at campus aggregation, data centre top-of-rack and service provider aggregation, with EVPN-VXLAN, MC-LAG and Virtual Chassis support for modern fabric designs.
