Deployment / Use Cases
This switch is ideal for data center top-of-rack deployments, where its 24x 10GbE ports can connect hyper-converged infrastructure or virtualized hosts, while the 100GbE uplinks maintain high-bandwidth paths to the network core. It also serves effectively as a distribution layer switch in large campus or enterprise networks, aggregating access switches and providing Layer 3 segmentation.
For storage networking, the low-latency, fiber-based connectivity supports iSCSI or NAS traffic, and the PoE capability allows consolidation by powering edge devices. The rack-mountable, 1U form factor fits standard 19-inch cabinets, making it suitable for space-constrained data centers or wiring closets.
Data Center Server Access
Connect racks of servers with 10GbE NICs, using 100GbE uplinks to spine switches for efficient east-west traffic flows.
Enterprise Network Core
Act as a core or distribution switch, routing between VLANs and aggregating multiple access switches with high-throughput uplinks.

User Manual
FAQ
What are the primary port types and counts on this HPE switch?
The HPE CX 8100 24XF4C provides 24 SFP+ ports for 10 Gigabit Ethernet connections and 4 QSFP28 ports for 100 Gigabit Ethernet uplinks. These QSFP28 ports also support 40 Gigabit Ethernet optics, giving you flexibility in uplink configuration. All ports are optical fiber-based, suitable for longer-distance, high-bandwidth links in data center or core network deployments.
Does this switch support Power over Ethernet (PoE)?
Yes, this switch includes PoE capability on its RJ-45 ports. This allows it to deliver power to compatible devices such as wireless access points, IP phones, or security cameras over the Ethernet cable, simplifying installation and reducing the need for separate power supplies at the edge of your network.
What does Layer 3 support mean for this switch?
Layer 3 support means the switch can perform IP routing between VLANs and subnets, enabling it to handle inter-VLAN traffic without an external router. This includes support for static routing and dynamic routing protocols, which simplifies network design, reduces latency, and improves scalability in larger enterprise or data center environments.
How many power supplies does this switch support, and why is that important?
The switch supports two power supplies, allowing for redundant power input. This means you can connect each power supply to separate electrical circuits or UPS units. If one power supply or circuit fails, the switch continues operating on the remaining supply, minimizing downtime and enhancing reliability in critical networking applications.
What are the physical dimensions and mounting options?
The switch measures 1.73 inches high, 17.42 inches wide, and 16 inches deep, fitting a standard 1U rack space. It is designed for rack-mountable, surface mount, or cabinet mount installation, providing flexibility for deployment in data center racks, network closets, or on flat surfaces where rack space is limited.
What type of fiber optic modules are compatible with this switch?
The switch supports SFP+ modules for 10GbE connections, QSFP+ for 40GbE, and QSFP28 for 100GbE over optical fiber. This includes a wide range of industry-standard transceivers for multimode or single-mode fiber, allowing you to choose optics based on distance requirements and existing fiber infrastructure in your network.
