Description

The Juniper EX3300 is an entry-level fixed-configuration 1U access switch suited to campus wiring closets and data-centre Gigabit Ethernet server access. This EX3300-48T-BF uses back-to-front airflow, which suits hot and cold aisle racks where the ports face the cold aisle at the rear.

It provides 48 10/100/1000BASE-T ports with no PoE, plus four dual-mode SFP+/SFP uplink ports that run at 10GbE or GbE. Switching capacity is 176 Gbps with 130 Mpps of Layer 2 and Layer 3 throughput. The unit has an internal AC power supply and a maximum system power consumption of 73 W. Virtual Chassis lets up to 10 members be managed as one logical device over four dedicated VC ports with an 80 Gbps interconnect.

It ships with the base Junos feature set covering Layer 2 and basic Layer 3 routing. The EX-48-EFL Enhanced Feature License is an optional purchase that adds OSPF, VRRP, BFD, Q-in-Q and IPv6 routing. The uplink ports accept SFP and SFP+ optics.

FAQs

Q: Does this switch need a licence?
A: No. It ships with the base Junos feature set covering Layer 2 and basic Layer 3. The optional EX-48-EFL Enhanced Feature License adds OSPF, VRRP, BFD, Q-in-Q and IPv6 routing.

Q: Does it support PoE?
A: No. The EX3300-48T-BF has no PoE budget. Choose the EX3300-48P if you need to power PoE devices from the switch.

Q: What optics fit the uplink ports?
A: The four uplink ports are dual-mode and accept SFP optics for GbE or SFP+ optics for 10GbE.

Q: How does back-to-front airflow differ from the standard model?
A: Cooling air flows from the rear of the switch to the front, so rear-facing ports sit in the cold aisle of a hot and cold aisle data-centre rack.

Q: Can I stack it with other switches?
A: Yes. Virtual Chassis lets up to 10 members be managed as one device over the four VC ports, with an 80 Gbps interconnect.
