3CR17451-91 3Com 44-Ports 10/100/1000Mbps SuperStack 3 Switch 3870 Network Switch

3Com 3CR17451-91

The 3Com 3CR17451-91 is a 44-port Gigabit Ethernet switch from 3Com, part of the 3Com SuperStack / Baseline Series, built for maintaining and extending existing installations built on this product family.

On the front panel you get 44 x 10/100/1000Mbps, ready for copper and fiber connections as your design requires. High port density reduces the number of switches you need in each rack, which saves space, power and management effort. Because it follows Ethernet standards, it works alongside equipment from other manufacturers. Fewer, larger switches make cable management and fault-finding simpler in busy comms rooms. Cat5e or Cat6 patch leads let each copper port reach its full Gigabit speed.

Its stackable design simplifies expansion and gives you one management point for several switches. Plan which ports will serve end devices and which will act as uplinks to keep cabling tidy and future changes simple. Keeping a record of what is connected to each port speeds up maintenance. Everyday business communication depends on dependable switching between users, servers and the internet. Reliable switching underpins every connected service, from email and file sharing to voice and video.

Adequate airflow around the unit helps it run reliably for years. Connecting it to a UPS protects your network from brief power cuts and surges. The 3CR17451-91 part number makes it easy to source identical units for future expansion. Proven, well-understood hardware is a cost-effective option for stable networks and labs. It is a practical choice for keeping 3Com-based networks running or for expanding them with matching hardware. The 3Com 3CR17451-91 is a smart investment for anyone who needs 3Com SuperStack / Baseline switching.
