3Com 4500 PWR 3CR17571-91

3Com's 4500 PWR, part number 3CR17571-91, is a managed Layer 3 Fast Ethernet PoE switch that brings enterprise access switching to established networks that need like-for-like replacements, spares or expansion units. The series is designed for enterprise access switching.

Its port layout is 24 x 10/100BASE-TX, 2 x 1000BASE-T, giving you a clear, flexible mix of connections. Higher-speed Gigabit connectivity is ideal for uplinks and aggregation, keeping traffic moving when many users are active. PoE support removes the need for separate power supplies for access points, IP cameras, VoIP phones and IoT sensors, cutting cabling cost and clutter. Fast Ethernet access is a budget-friendly way to connect large numbers of simple network devices.

Full management capabilities let your IT team tune performance, enforce policies and monitor every port. Its Layer 3 feature set supports inter-VLAN routing, so traffic between departments does not have to travel to a separate router. Switching sends each frame only where it needs to go, which keeps the network efficient. Email, file sharing, voice and video all depend on stable switching underneath. Labeling patch cables and documenting port assignments makes future moves, adds and changes much faster.

Connecting it to a UPS protects your network from brief power cuts and surges. Quote 3CR17571-91 when ordering to receive this exact configuration. It is a practical choice for keeping 3Com-based networks running or for expanding them with matching hardware. Whether you are building a new network or replacing an existing unit, the 3CR17571-91 delivers PoE switching that fits the job.
