C1000-24T-4G-L Description
C1000-24T-4G-L is a Cisco Catalyst 1000 Series fixed managed Gigabit Ethernet Layer 2 switch with 24 10/100/1000 RJ45 data ports and 4 fixed 1G SFP uplinks.
The SKU fits access closets where copper endpoints need data connectivity but not switch-supplied PoE power. In the same 24-port 1G-uplink group, C1000-24P-4G-L adds PoE+ with a 195W budget, while C1000-24T-4X-L keeps the data-port role and changes the uplinks to 10G SFP+.
Quote review should confirm the 24-port data-only requirement, 1G SFP optic plan, 100 to 240V AC input, fanless installation location, rack or wall mounting method, and any service or shipping terms tied to the final bill of materials.

Product Performance
Key Features
The model provides 24 Gigabit RJ45 data ports, so it should be selected when endpoint power is handled separately or not required.
The uplink profile is 4 x 1G SFP, which keeps the aggregation design in the 1G fiber tier instead of the 10G SFP+ tier used by C1000-24T-4X-L.
Cisco marks this 24-port data model as fanless, a useful fit for quiet branch closets, retail spaces, offices, or classroom cabinets with proper clearance.
Catalyst 1000 switches operate on Cisco IOS Software and support CLI and on-box web UI management for smaller Cisco access networks.
The switch uses a single fixed internal AC power supply, so the order should be checked against the local AC circuit, power cord, UPS capacity, and optional cord retainer.
Cisco documents 802.1X, SPAN, BPDU Guard, sFlow, SNMP, and related Layer 2 functions across the Catalyst 1000 family.
Application Scenarios
C1000-24T-4G-L fits a small branch, office, retail, or classroom access closet where 24 Gigabit copper endpoints need switching but powered devices do not draw power from the switch.
The SKU works for sites standardized on four 1G SFP uplinks into the upstream layer, especially when the design does not justify the 10G SFP+ uplink model.
The fanless 24-port chassis suits edge placements near users, provided the temperature range, optic selection, mounting method, and AC power plan are confirmed before installation.

Ordering description |
24x 10/100/1000 Ethernet ports, 4x 1G SFP uplinks |
24x 10/100/1000 Ethernet PoE+ ports and 195W PoE budget, 4x 1G SFP uplinks |

48x 10/100/1000 Ethernet ports, 4x 1G SFP uplinks |
- In a C1000-24T-4G-L vs C1000-24P-4G-L comparison, the difference is endpoint power: both stay in the 24-port 1G SFP uplink class, but C1000-24P-4G-L adds PoE+ with a 195W budget.
- The C1000-24T-4G-L difference from C1000-24T-4X-L is uplink speed, because the 4X data model changes the uplinks from 1G SFP to 10G SFP+ and moves to the higher forwarding-rate class.
- For C1000-24T-4G-L vs C1000-48T-4G-L, the comparison is port count and hardware profile: the 48T model doubles the copper 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 copper ports and 1G SFP or 10G SFP+ uplinks.
Selection Guide
1. Choose it for 24-port data-only access
Select C1000-24T-4G-L when the BOM requires 24 Gigabit RJ45 data ports, 4 x 1G SFP uplinks, fanless hardware, and no switch PoE budget.
2. Move to PoE+ only when endpoints need power
Choose C1000-24P-4G-L instead when phones, cameras, access points, or other powered devices must draw from a Cisco-listed 195W PoE budget.
3. Use the 4X data model for 10G uplinks
Specify C1000-24T-4X-L when the access-port count stays at 24 but the upstream design requires 10G SFP+ uplinks rather than 1G SFP.
4. Use the 48T model for higher copper density
Select C1000-48T-4G-L when the site needs 48 data ports in the same 1G SFP uplink class and can accept the larger non-fanless chassis profile.
Ordering Checklist

Order Review Area |
Cisco-confirmed Item |
Procurement Check |
|---|---|---|
|
Switch identity |
C1000-24T-4G-L |
Match the line item to the 24-port Catalyst 1000 data switch before substituting any PoE or 10G-uplink variant |
|
Copper access scope |
24 x 10/100/1000 RJ45 data ports |
Confirm endpoint power is not expected from the switch because this SKU is not the PoE+ model |
|
Fiber handoff |
4 x 1G SFP uplinks |
Prepare the 1G SFP optic plan and avoid assuming the 10G SFP+ uplink tier |
|
Variant boundary |
C1000-24P-4G-L adds 195W PoE+, and C1000-24T-4X-L changes to 10G SFP+ uplinks |
Use the alternate SKU only when the requirement changes to powered endpoints or 10G aggregation |
|
Site electrical input |
100 to 240V AC input, 50 to 60 Hz, 0.29A to 0.47A current, and 0.08 kVA power rating |
Align the switch with the rack power strip, UPS capacity, and regional AC cord |
|
Optic temperature check |
GLC-BX-U or GLC-BX-D use changes the documented operating-temperature ceiling |
Review the cabinet temperature if bidirectional SFP modules are part of the uplink bill of materials |
|
Installation accessories |
24-port models include 19 in. mounting brackets; CAB-CONSOLE-RJ45 and PWR-CLP are compatible accessories |
Add console access and cable-retention items only when the installation package requires them |
