Compact 12-Port Managed Switch

The HPE Juniper Networking EX2300-C-12T is a compact, fanless managed switch built for small network environments where space and power are at a premium. It provides 12 front-panel 10/100/1000BASE-T access ports and two SFP/SFP+ uplink ports for fibre connectivity. The desktop form factor delivers complete Layer 2 and basic Layer 3 switching capabilities for branch offices, retail sites and workgroups outside the wiring closet.

Upgrade From Unmanaged Or Larger Chassis

This switch replaces unmanaged desktop units when VLAN segmentation, QoS policies or Layer 3 routing between up to 512 IPv4 prefixes are required. It also serves as a space-saving alternative to full-depth rack switches in micro-branch deployments where only 12 copper ports are needed. The jump is worth it when silent operation, Virtual Chassis stacking of up to four units or Junos Fusion satellite management simplify operations.

Verify Uplink Optics And Mounting Space

Confirm that SFP or SFP+ transceivers are sourced separately because the two uplink ports ship empty. Check that the 27.9 cm width, 4.4 cm height and 23.9 cm depth fit the intended shelf, desk or 1U rack tray. Ensure the management workflow matches Junos OS expectations, as the switch does not support PoE and requires no external power supply beyond its internal unit.

Questions about this item

What are the exact dimensions of the EX2300-C-12T in centimetres so I can check it fits my cabinet?

The switch measures 27.9 cm wide, 4.4 cm high and 23.9 cm deep, making it a 1U desktop form factor.

How do I mount the EX2300-C-12T in a standard rack and what is the common mistake?

Use the included rack-mount brackets to secure the 1U chassis; the step often missed is tightening both front and rear bracket screws to prevent vibration.

Are there any fans or filters in the EX2300-C-12T that will need cleaning or replacement later?

The unit is fanless with no moving parts or filters, so no scheduled internal maintenance is required.
