Overview of Cisco CBS250-16T-2G 16-Port Gigabit Ethernet Smart Switch with SFP (NA) | Refresh
The Cisco CBS250-16T-2G 16-Port Gigabit Ethernet Smart Switch with SFP (NA) delivers fiber-ready uplinks, reliable wired access and necessary Layer 2/Layer 3 networking services for small and medium business networks. This Cisco Business 250 Series switch offers a scalable foundation for connecting PCs, printers, wireless access points, servers, VoIP phones and other business devices due to its 16 Gigabit RJ-45 ports and two dedicated 1G SFP uplink connections. The CBS250-16T-2G, in contrast to an unmanaged switch, provides managers with useful control over security rules, VLAN segmentation, QoS and static routing via an easy-to-use web interface, CLI, SNMP and Cisco Business Dashboard. For businesses that require secure, high-performance Gigabit switching without the expense and complexity of a fully managed enterprise access switch, this non-PoE rack-mountable switch is an excellent option.

Frequently Asked Questions
Cisco CBS250-16T-2G 16-Port Gigabit Ethernet Smart Switch with SFP
Frequently Asked Questions (FAQ's)
How many Ethernet ports does the CBS250-16T-2G have?
The switch has 16 10/100/1000 Mbps RJ45 Gigabit Ethernet access ports.
How many SFP ports are included?
It provides two dedicated 1 Gigabit SFP slots, giving the switch 18 total Gigabit interfaces.
Are the SFP ports shared with the RJ45 ports?
No. On the CBS250-16T-2G, Cisco lists 16 RJ45 interfaces plus two separate SFP interfaces. They are not the copper/SFP combo ports used on certain 8-port CBS250 models.
Are the SFP uplinks 10 Gigabit?
No. The two uplinks are 1 Gigabit SFP interfaces. They are not SFP+ 10G ports. Cisco's CBS250 models ending in “4X” are the configurations equipped with 10G SFP+ uplinks.
Does the CBS250-16T-2G support PoE?
No. The 16T model does not supply PoE. Cisco lists the CBS250-16P-2G as the corresponding 16-port PoE+ model with a 120W budget.
Can I connect an IP phone to this switch?
Yes. An Ethernet-based IP phone can connect for data, but because the CBS250-16T-2G does not provide PoE, the phone must receive power through its own AC adapter or another appropriate power source.

Yes. The Cisco Business 250 platform supports IEEE 802.1Q VLANs and multiple VLAN-management features for segmenting network traffic.
Does it support Layer 3 routing?
Yes. Cisco includes Layer 3 static routing on the Business 250 Series, allowing suitable traffic to be routed between configured IP networks and VLANs.
Does the CBS250-16T-2G support QoS?
Yes. It has eight hardware queues and supports Strict Priority, Weighted Round Robin, DSCP, 802.1p, DiffServ, rate limiting and other QoS functions.
Is the CBS250-16T-2G fanless?
Yes. Cisco specifies the model as fanless, allowing silent operation.
Is the switch rack mountable?
Yes. Cisco identifies the CBS250-16T-2G as rack mountable and includes a mounting kit in the standard package.
What are the switch dimensions?
Cisco lists dimensions of approximately 10.56 × 10.69 × 1.73 inches (268 × 272 × 44 mm).
How much does it weigh?
The unit weighs approximately 3.92 lb (1.78 kg).
What type of power supply does it use?
The CBS250-16T-2G has an internal universal 100–240V AC, 50/60 Hz power supply.
How much power does the switch consume?
Cisco lists worst-case system power consumption at approximately 18.63W at 110V and 18.37W at 220V.
How large is the MAC address table?
The Cisco Business 250 Series supports an 8K MAC address table.
Does the switch support jumbo frames?
Yes. Cisco specifies support for jumbo Ethernet frames of up to 9K bytes.
How can the switch be managed?
Management options include the on-device web interface, CLI, Cisco Business Dashboard, SNMP, HTTP/HTTPS, SSH, RADIUS, syslog, and other standard tools.
Is the Cisco CBS250 Series discontinued?
Yes. Cisco’s current support page identifies the Business 250 Series as End of Sale. Cisco lists an end-of-sale date of January 31, 2025 and an end-of-support date of October 31, 2029. Cisco recommends the Catalyst 1200 Series as the current upgrade path.
Who is the CBS250-16T-2G best suited for?
It is well suited to small businesses, offices, schools, retail locations, workgroups and branch environments that need 16 managed Gigabit ports, fiber uplinks, VLANs, static routing, QoS and network security without PoE. Organizations needing powered IP phones, cameras, or access points should consider a PoE-capable model or separate PoE equipment.
