Description

The EX4400 is a 1 U fixed multigigabit access switch for enterprise campus, branch and data centre access layers. It suits Wi-Fi 7 access points, IoT and other high-power PoE devices that need multigigabit uplinks to the edge, with MACsec encryption and cloud management through Juniper Mist.

This EX4400-48MXP-S is a spare chassis with 12 x 100M/1/2.5/5/10GbE and 36 x 100M/1/2.5GbE multigigabit ports. All 48 ports support IEEE 802.3bt PoE++ at up to 90 W per port. Two built-in 100GbE QSFP28 ports serve as uplinks or Virtual Chassis stacking, and an extension module slot adds further 100G, 25G or 10G ports. Switching capacity is 1020 Gbps with 758 Mpps throughput. It runs Junos OS (ELS).

The spare chassis ships without power supplies or fan modules, which are ordered separately. It accepts 2000 W AC or 2000 W DC power supplies, and dual AC supplies provide up to 3600 W of PoE budget. Extension modules are EX4400-EM-1C, EX4400-EM-4S and EX4400-EM-4Y.

FAQs

Q: Does this spare chassis include power supplies or fans?
A: No. The EX4400-48MXP-S spare chassis is supplied without power supplies or fan modules, so these must be ordered separately.

Q: Which power supplies does it use and what PoE budget can it provide?
A: It supports 2000 W AC or 2000 W DC power supplies. Dual 2000 W AC supplies give a PoE budget of up to 3600 W, and each port can deliver up to 90 W under IEEE 802.3bt.

Q: Which extension modules fit this switch?
A: The extension module slot accepts the EX4400-EM-1C (1x100GbE QSFP28), EX4400-EM-4S (4x10GbE SFP+) and EX4400-EM-4Y (4x25GbE SFP28).

Q: Does it need a licence or subscription?
A: It runs Junos OS (ELS). Cloud management through Juniper Mist Wired Assurance is a subscription, and optional Junos feature licences apply for advanced features.

Q: Can the 100G ports be used for stacking?
A: Yes. The two built-in 100GbE QSFP28 ports work as uplinks or as Virtual Chassis stacking ports, with up to 10 members per Virtual Chassis.
