Why buy Cisco from XS Network Tech?
We are the independent Cisco specialist Australian IT teams, data centres, and government departments rely on for speed and availability. Unlike other resellers, we hold our own stock in Australia. With us you bypass the 4 - 8 week lead times that slow most Cisco procurement down. From pre-sales to fulfilment, our team moves as fast as your project.
-
Can I still buy discontinued Cisco models?
Yes, we supply both current-generation Cisco switches, routers, and modules and end-of-life (EOL) models that other resellers no longer stock. We hold stock for discontinued Catalyst, Nexus, ISR, ASR, and UCS models. Whether you need a like-for-like spare, a cost-effective upgrade, or a legacy model to extend your existing deployment, we can source it.
