Description

The Catalyst 3750-X is a stackable, enterprise-class 1 RU access switch for campus and branch wiring closets. This model provides 48 10/100/1000 PoE+ ports and ships with the IP Services feature set, making it suited to routed access deployments that also need to power IP phones, wireless access points and video endpoints.

Each port can deliver up to 30W of PoE+. The 715W AC power supply provides a 435W PoE budget, so full 30W delivery on all 48 ports needs larger or additional power supplies. Switching fabric is 160 Gbps with a forwarding rate of 101.2 mpps (with two 10GbE uplinks). Cisco StackWise Plus gives 64 Gbps of stacking throughput across up to nine switches, and StackPower lets up to four stack members share power capacity. The switch accepts optional hot-swappable uplink network modules in 4x 1G SFP, 2x 10G SFP+, 2x 10GBASE-T and service module variants.

IP Services is the highest feature tier and covers advanced Layer 3 routing for IPv4 and IPv6, including OSPF, EIGRP, BGP, policy-based routing and VRF-Lite. The chassis has redundant modular power supply and fan bays and works with the C3KX power supply range (350W, 715W, 1100W AC and 440W DC).

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: Which feature set does this switch run?
A: It runs the IP Services (E) feature set, the highest of the three tiers (LAN Base, IP Base, IP Services). It is required for full OSPF, EIGRP, BGPv4, IS-ISv4, PIM, policy-based routing, VRF-Lite and IP SLA.

Q: Can it deliver 30W PoE+ on all 48 ports?
A: The default 715W power supply provides a 435W PoE budget. For 30W on every port you need two C3KX-PWR-1100WAC supplies, or one 1100W plus one 715W.

Q: Which uplink modules and power supplies does it work with?
A: Uplink modules are C3KX-NM-1G, C3KX-NM-10G, C3KX-NM-10GT and C3KX-SM-10G. Power supplies are C3KX-PWR-350WAC, -715WAC, -1100WAC and -440WDC.

Q: Can it be stacked with other switches?
A: Yes. StackWise Plus supports up to nine switches at 64 Gbps and is backward compatible with Catalyst 3750 Series. A LAN Base stack cannot be mixed with IP Base or IP Services switches.

Q: What redundancy options are available for power?
A: A second power supply, either AC or 440W DC, can be added for redundancy. If only one supply is installed it must be in bay 1. StackPower also lets up to four stack members share power.
