Fortinet’s official data sheet specifies the FS-148E’s 48 × GE RJ45 interfaces, 4 × GE SFP interfaces, 104 Gbps switching capacity, 155 Mpps forwarding rate, 16K MAC table, and 1.5 MB packet buffer.
48 × Gigabit Ethernet RJ45 Ports
The FS-148E provides 48 Gigabit Ethernet copper ports for high-density network access.
These ports can be used to connect:
- Desktop computers
- Servers
- Printers
- IP phones
- Network appliances
- Wireless access points
- Security devices
- IoT and enterprise endpoints
- Other Ethernet switches
The FS-148E is a non-PoE model, so its RJ45 ports do not provide PoE power.
4 × Gigabit SFP Uplink Ports
Four Gigabit Ethernet SFP ports provide fiber-based connectivity for uplinks and network expansion.
They can be used for:
- Fiber uplinks
- Switch-to-switch connections
- Campus backbone connections
- Longer-distance links
- Network aggregation
- Fiber-based infrastructure
SFP transceivers are not included unless specifically supplied with the exact product SKU or bundle.
Switching Performance
The FS-148E is designed to provide high-speed Layer 2 switching for enterprise access networks.
| Performance Metric | FS-148E |
|---|---|
| Switching Capacity | 104 Gbps |
| Packet Forwarding | 155 Mpps |
| MAC Addresses | 16K |
| VLANs | 4K |
| Latency | 3,860 ns |
| Packet Buffer | 1.5 MB |
These are manufacturer specifications; actual network throughput can vary depending on packet size, traffic patterns, configuration, and connected equipment.
Layer 2 Networking
The FS-148E supports enterprise Layer 2 networking features for segmentation, redundancy, and traffic management.
Capabilities include:
- VLANs
- 802.1Q VLAN tagging
- Spanning Tree Protocol
- Rapid Spanning Tree
- Multiple Spanning Tree
- Link aggregation
- LACP
- LLDP

- BPDU protection
- Private VLAN capabilities
The switch supports up to 4,000 VLANs, with up to 32 spanning-tree instances.
Link Aggregation
The FS-148E supports link aggregation for combining multiple physical links into a logical connection.
It supports:
- Up to 8 ports per LAG
- Up to 16 LAG groups
- LACP
- Increased aggregate bandwidth
- Link redundancy
Link aggregation can be used for switch uplinks, server connections, and other applications requiring additional bandwidth or resiliency.
Layer 3 Networking
The FS-148E supports Layer 3 networking capabilities through FortiSwitchOS, allowing it to participate in routed enterprise network architectures.
Depending on the FortiSwitchOS release and deployment mode, supported capabilities can include:
- Static routing
- IPv4/IPv6 routing
- DHCP relay
- Dynamic routing features
- Multicast networking
- VRRP
- Policy-based routing
For exact feature availability, Fortinet recommends checking the applicable FortiSwitch feature matrix and FortiSwitchOS release for the deployed version.
FortiLink & FortiGate Integration
The FS-148E can be integrated with FortiGate using FortiLink.
This enables centralized management and visibility across the Fortinet network environment, including:
- Switch discovery
- Centralized configuration
- VLAN management
- Port configuration
- Device monitoring
- Network segmentation
- Firmware management
- Security Fabric integration
- Authentication and access control
Fortinet’s current documentation continues to list the FS-148E as a supported FortiSwitch model in FortiSwitchOS releases.
Security Features
The FS-148E supports enterprise access-control and network-security functions such as:

Important Compatibility Note
The FS-148E is the non-PoE version of the FS-148E family and provides 48 × GE RJ45 + 4 × GE SFP interfaces.
Fortinet also identifies FS-148E-POE as a separate model. Therefore, do not advertise PoE functionality or a PoE power budget for an FS-148E unless the physical unit is specifically the PoE variant.
SFP transceivers and fiber cables should also be treated as separate accessories unless explicitly included in the supplied package.
