Deployment / Use Cases
This switch is well-suited for environments where space, power, and connectivity need to be optimized in a single device. Its combination of PoE+ capability and management features makes it versatile for various small to medium business scenarios.
Typical deployments include small office networks where the switch can power VoIP phones and wireless access points while providing connectivity to workstations and servers. The rack-mountable design makes it ideal for structured wiring closets or small server rooms where organized cable management is important.
Small Office Networking
Deploy as the core switch in offices with 8 or fewer wired devices, providing both connectivity and power to IP phones, wireless access points, and other PoE-enabled equipment.
Branch Office Connectivity
Use in remote locations where fiber uplinks connect back to headquarters, with PoE+ supporting local devices without additional power infrastructure.
Physical Profile
The switch features a compact 1U rack-mountable design that fits standard 19-inch racks, with dimensions of 1.70 inches high, 10.60 inches wide, and 7.30 inches deep. This space-efficient form factor makes it suitable for environments where rack space is limited, such as small network closets or wall-mounted racks.
The 7.72-pound weight and sturdy construction ensure stable mounting in rack environments, while the front-facing ports and status indicators provide easy access and visibility during installation and maintenance.

User Manual
FAQ
What is the total PoE budget of this switch?
The Cisco CBS250-8PP-E-2G has a total PoE budget of 45 watts. This budget is shared across all eight PoE+ ports, with each port capable of delivering up to 25.5 watts to connected devices such as IP phones, wireless access points, or security cameras. The switch intelligently allocates power based on device requirements and priority settings.
How many SFP slots does this switch have?
This switch features two SFP (Small Form-factor Pluggable) slots, also referred to as mini-GBIC slots. These slots support fiber optic transceivers for connecting to other network devices over longer distances. The shared SFP slot design allows flexible configuration options depending on your network topology and connectivity requirements.
What does 'Layer 2' mean for this switch?
Layer 2 refers to the data link layer of the OSI model. This switch operates at Layer 2, which means it can perform switching functions based on MAC addresses, support VLANs for network segmentation, implement Quality of Service (QoS) for traffic prioritization, and enable link aggregation for increased bandwidth. These features provide basic network management capabilities without the complexity of Layer 3 routing.
Is this switch rack-mountable?
Yes, the Cisco CBS250-8PP-E-2G is designed for rack mounting with a standard 1U form factor. It includes mounting brackets for installation in 19-inch equipment racks commonly found in server rooms, network closets, or data centers. The compact dimensions of 1.70" H × 10.60" W × 7.30" D make it suitable for space-constrained environments while providing all necessary connectivity.
What management options are available?
This managed switch offers both web-based and command-line interface (CLI) management options. The web interface provides a graphical configuration environment accessible through a standard browser, while the CLI offers advanced configuration capabilities for network administrators. Management features include port configuration, VLAN setup, QoS policies, monitoring, and troubleshooting tools.
What does 'refurbished' mean for this product?
Refurbished means this switch has been professionally tested, cleaned, and restored to full working condition. It undergoes quality checks to ensure all components function properly and meets Cisco's standards for refurbished equipment. Refurbished products offer a cost-effective alternative to new equipment while providing the same core functionality and reliability, often with significant savings.
