Product Performance
Key Features
The switch provides 24 Gigabit RJ45 data ports and no PoE budget, keeping the line item focused on copper data access rather than powered endpoints.
The 4X model gives the same 24-port access count as the 4G data model but changes the uplink side to four SFP+ slots for 10G handoff.
Cisco marks this model as fanless, which is useful when the switch must sit near users in a small office, classroom, retail cabinet, or edge closet.
Catalyst 1000 switches use a single universal Cisco IOS Software image with advanced Layer 2 functionality, which keeps software planning consistent across the series.
Cisco documents a single fixed internal power supply for Catalyst 1000 switches, so ordering checks should focus on AC input, regional power cable, UPS capacity, and cable retention.
The Catalyst 1000 feature set includes 802.1X, SPAN, BPDU Guard, sFlow, SNMP, and related Layer 2 controls used in managed access deployments.
Application Scenarios
C1000-24T-4X-L fits a branch, office, or small campus access closet where 24 copper endpoints need Gigabit switching and the upstream design already calls for 10G SFP+ uplinks.
The SKU is a practical match for quiet edge cabinets when the site can provide suitable airflow, operating temperature, rack or wall mounting, and the correct AC power connection.
Use this hardware path when phones, cameras, or access points are powered separately, because C1000-24P-4X-L is the adjacent 10G-uplink model that adds a 195W PoE budget.

- In a C1000-24T-4X-L vs C1000-24T-4G-L comparison, the difference is uplink speed: both are 24-port data switches, but the current SKU uses four 10G SFP+ uplinks instead of four 1G SFP uplinks.
- The C1000-24T-4X-L difference from C1000-24P-4X-L is PoE scope, because both stay in the 24-port 10G-uplink class while C1000-24P-4X-L adds a 195W PoE budget.
- For C1000-24T-4X-L vs C1000-48T-4X-L, the comparison centers on copper port count and cooling profile: the C1000-48T model doubles the data ports and is not fanless.
- The which model to choose check should start with data-only versus PoE access, then confirm whether the uplink design is 1G SFP or 10G SFP+ and whether the site needs 24 or 48 copper ports.
Selection Guide
1. Choose it for data-only access with 10G uplinks
Select C1000-24T-4X-L when the BOM requires 24 Gigabit RJ45 data ports, four 10G SFP+ uplinks, fanless hardware, and no switch PoE budget.
2. Stay with the 4G model for 1G fiber uplinks
Use C1000-24T-4G-L when the access count remains 24 data ports but the aggregation layer only requires four 1G SFP uplinks.
3. Move to the PoE 4X model for powered endpoints
Specify C1000-24P-4X-L when the same 10G-uplink class is required and attached phones, cameras, or access points must draw from a Cisco-listed 195W PoE budget.
4. Use the C1000-48T 4X model for higher data density
Choose C1000-48T-4X-L when the project needs 48 non-PoE Gigabit copper ports with 10G SFP+ uplinks and can accept the larger non-fanless chassis profile.
Ordering Checklist
|
Check Item |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact switch model |
C1000-24T-4X-L |
Match the line item to the 24-port data model before substituting a PoE or 48-port variant |
|
Access port role |
24 x 10/100/1000 RJ45 data ports |
Confirm endpoints do not need switch-supplied PoE power |
|
Uplink tier |
4 x 10G SFP+ uplinks |
Prepare the SFP+ optic plan instead of assuming 1G SFP uplinks |
|
Long-reach SFP+ thermal check |
SFP-10G-ER or SFP-10G-ER-S use lowers the documented temperature ceiling at altitude |
Review cabinet temperature if those optics are part of the uplink bill of materials |
|
Site power |
100 to 240V AC input, 50 to 60 Hz, 0.29A to 0.51A current, and 0.08 kVA power rating |
Align the switch with the local AC circuit, UPS capacity, and regional power cable |
|
Variant boundary |
C1000-24T-4G-L uses 1G SFP uplinks, and C1000-24P-4X-L adds 195W PoE |
Use an alternate SKU only when the uplink speed or endpoint power requirement changes |
