C1000-48T-4G-L Description
C1000-48T-4G-L is a Cisco Catalyst 1000 Series fixed managed Gigabit Ethernet Layer 2 data switch with 48 10/100/1000 RJ45 Ethernet ports and four 1G SFP uplinks.
The key order difference is endpoint power and uplink tier. C1000-48P-4G-L keeps the same 48-port and 4 x 1G SFP uplink class but adds PoE+ with a 370W budget, while C1000-48T-4X-L stays data-only and changes the uplinks to 10G SFP+.
Quote review should confirm that endpoints do not require switch PoE, the uplink bill of materials uses 1G SFP optics, the site can support a non-fanless 48-port chassis, and the AC input, power cord, rack installation, warranty support, stock status, and global shipping terms match the final order.

Product Performance
Key Features
The model provides 48 Gigabit RJ45 data ports, making it the 48-port choice when phones, cameras, access points, or other endpoints do not need power from the switch.
The uplink profile is 4 x 1G SFP, so the fiber plan should be built around 1G transceivers rather than the 10G SFP+ optics used by C1000-48T-4X-L.
Cisco marks 48-port Catalyst 1000 models as not fanless, and the data sheet lists 31.5 dB typical sound pressure for the 48T 4G and 4X models.
Catalyst 1000 switches operate on Cisco IOS Software and support management through CLI and an on-box web UI for smaller Cisco access networks.
The switch uses a fixed internal AC power supply, so the practical order checks are the 100 to 240V AC input range, UPS load, regional power cable, and optional cord retainer.
Cisco documents access-switch functions such as 802.1X, IPv4 and IPv6 ACLs, BPDU Guard, SPAN, SNMP, and sFlow across the Catalyst 1000 family.
Application Scenarios
C1000-48T-4G-L fits branch, school, retail, and office closets where many wired endpoints need Gigabit switching but endpoint power is handled outside the access switch.
Use this SKU when the upstream design is standardized on four 1G SFP uplinks and the access layer does not require the 10G SFP+ handoff of C1000-48T-4X-L.
The model is a clear step from C1000-24T-4G-L when the design keeps the same data-only and 1G SFP uplink profile but requires 48 copper access ports.

- In a C1000-48T-4G-L vs C1000-48T-4X-L comparison, the confirmed difference is uplink speed: both are 48-port data models, but the 4X variant changes the uplinks from 1G SFP to 10G SFP+.
- The C1000-48T-4G-L difference from C1000-48P-4G-L is endpoint power, because both stay in the 48-port 1G SFP class while the 48P model adds a 370W PoE budget.
- For C1000-48T-4G-L vs C1000-24T-4G-L, the comparison centers on copper port count and chassis profile: the current SKU doubles the data ports and is not fanless.
- The which model to choose check should start with PoE requirement, then confirm whether the site needs 24 or 48 ports and 1G SFP or 10G SFP+ uplinks.
Selection Guide
1. Choose it for 48-port data-only access
Select C1000-48T-4G-L when the bill of materials needs 48 Gigabit RJ45 data ports, four 1G SFP uplinks, and no switch PoE budget.
2. Move to C1000-48T-4X-L for 10G aggregation
Use C1000-48T-4X-L when the endpoint count and data-only role stay the same but the upstream design requires four 10G SFP+ uplinks.
3. Use C1000-48P-4G-L when endpoints need PoE+
Specify C1000-48P-4G-L when the same 48-port and 1G uplink class is correct but phones, cameras, access points, or other powered devices must draw from a 370W switch PoE budget.
4. Keep C1000-24T-4G-L for smaller quiet access
Choose C1000-24T-4G-L when 24 data ports are enough and the installation needs the fanless 24-port hardware profile.
