Description

The Juniper EX4300-48P-S is a spare chassis from the EX4300 line, a 1U fixed-configuration Layer 2/3 access switch for campus, branch-office and data-centre edge deployments. It suits sites that need PoE+ for IP telephony, CCTV cameras and wireless access points, and supports pay-as-you-grow Virtual Chassis designs.

The switch provides 48 10/100/1000BASE-T ports with 802.3at PoE+ delivering up to 30 W per port, plus four fixed 40GbE QSFP+ ports preconfigured as Virtual Chassis ports with a 320 Gbps backplane. Up to 10 members can be managed as a single logical device. Switching capacity is 248 Gbps unidirectional (496 Gbps bidirectional) at 369 Mpps wire speed. As a spare chassis SKU, the unit is sold without power supplies or fan modules, and a 900 W PoE budget is available when fitted with an 1100 W AC power supply.

It works with the EX-UM-4X4SFP 4-port 1GbE/10GbE SFP+ uplink module for 10G uplinks, and with JPSU-715-AC-AFO or JPSU-1100-AC-AFO power supplies and EX4300-FAN fan modules. Junos OS is licensed through the Flex tiers, with Standard features available on the shipped image.

FAQs

Q: What licence does this switch use?
A: It runs Junos OS with Flex licensing in Standard, Advanced and Premium tiers. Standard-tier features are available on the shipped Junos OS image, with Advanced and Premium as optional upgrades. MACsec requires a separate licence.

Q: What power supplies does it need?
A: This is a spare chassis, so it needs JPSU-715-AC-AFO or JPSU-1100-AC-AFO AC power supplies together with EX4300-FAN fan modules. With the 1100 W AC supply the switch provides a 900 W PoE+ budget.

Q: How do I get 10G SFP+ uplinks?
A: Fit the optional EX-UM-4X4SFP uplink module, which adds four 1GbE/10GbE SFP+ ports. The four fixed 40GbE QSFP+ ports are preconfigured as Virtual Chassis ports.

Q: Can it be stacked with other switches?
A: Yes. Virtual Chassis lets up to 10 EX4300 or EX4600 switches operate as a single logical device over the 40GbE QSFP+ ports, with a 320 Gbps backplane.

Q: Which optics and cables does it support?
A: It supports 1GbE SFP SX/LX, 10GbE SFP+ SR, USR, LR, ER, LRM and DAC, and 40GbE QSFP+ SR4 and DAC, including QFX-QSFP-40G-SR4 and QFX-QSFP-DAC-1M and 3M.
