When you order a Sophos license from us please make sure you include the license number or current hardware appliance serial number. Licenses generally take around 24 - 36 working hours to be issued after order.

In some instances you may find we show out of stock for certain hardware models. This is fairly normal and reflects the fact, often that we have to place what is called a back to back order. When you order with us, we order with Sophos and the unit is shipped in to the country. Please allow around 10 working days where we show as out of stock.

The D-Link DMS-1250-12TP is a 12-port Multi-Gigabit Smart Managed PoE+ switch built for modern Wi-Fi 6 and Wi-Fi 6E networks. It combines eight 2.5G PoE+ ports for downlinks with two 10GBASE-T ports and two 10G SFP+ ports for uplinks, all backed by a generous 240W PoE budget. The 2.5Gbps ports let you make full use of existing cabling and remove bottlenecks for high-performance access points, IP cameras and IoT devices.

Part number DMS-1250-12TP delivers power and data over a single cable, simplifying deployment while leaving room for future growth. With a 120Gbps switching capacity and a feature-rich Layer 2+ software suite, it is a versatile choice for small and medium-sized networks.
