Description

The Juniper EX4650 is a 1U Ethernet switch for campus distribution and aggregation, enterprise top-of-rack and service provider aggregation. It runs Junos OS and suits designs that pair 25G access with 100G uplinks, whether as a Virtual Chassis of up to four members or as an EVPN-VXLAN campus fabric.

This EX4650-48Y-AFO provides 48 SFP28 ports that accept 1/10/25GbE optics and 8 QSFP28 ports for 40/100GbE. Switching capacity is 4 Tbps bidirectional at 2976 Mpps, with latency as low as 550 ns. It is powered by two 650 W AC supplies in a 1+1 redundant arrangement and cooled by redundant 4+1 hot-swap fan modules, with AFO airflow from port-side intake to PSU-side exhaust. The Base Junos licence is included, with optional Premium and Advanced tiers adding BGP, IS-IS, EVPN-VXLAN and MPLS.

The ports support SFP, SFP+ and SFP28 optics and DACs, QSFP+ and QSFP28 optics and DACs, plus 4x25G and 4x10G breakout cables. Replacement parts include JPSU-650W-AC-AFO power supplies, QFX5110-FANAFO fan modules and the EX-4PST-RMK rack kit.

FAQs

Q: Does this switch need a licence?
A: No licence key is needed to run it. The Base Junos OS licence is included. Optional Premium (EX4650-PFL, adds BGP, IS-IS and EVPN-VXLAN) and Advanced (EX4650-AFL, adds MPLS) licences are perpetual per-device licences and are not portable.

Q: What power does it use?
A: It runs from two 650 W hot-swap AC power supplies in a 1+1 redundant arrangement on 110-240 V single phase. Maximum draw is 450 W, typical 260 W and idle 160 W. It does not provide PoE.

Q: What airflow does the AFO version use?
A: AFO is front-to-back airflow, with air drawn in at the port side and exhausted at the PSU side. Racks need to be laid out to suit, and replacement fans and PSUs must also be AFO types such as QFX5110-FANAFO and JPSU-650W-AC-AFO.

Q: Which optics and cables work with the ports?
A: The SFP28 ports take SFP 1GbE, SFP+ 10GbE and SFP28 25GbE optics and DACs. The QSFP28 ports take QSFP+ 40G and QSFP28 100G optics and DACs, as well as 4x25G and 4x10G breakout cables.

Q: Can multiple EX4650 switches be managed as one?
A: Yes. Virtual Chassis lets up to four EX4650 switches operate as a single logical device. They can also be managed through Juniper Mist Wired Assurance or Junos Space.
