N2K-C2248TP-E-1GE Description
N2K-C2248TP-E-1GE is a Cisco Nexus 2248TP-E Fabric Extender for rack-edge 1G copper host connectivity under a Nexus parent switch. It provides 48 100/1000BASE-T host interfaces, four 10G SFP+ fabric interfaces, 10G SFP+ fabric media, 40 Gbps fabric speed in each direction / 80 Gbps full duplex, 176 Gbps / 131 Mpps hardware forwarding, 32 MB shared buffer, 32,000 MAC addresses, one included fan module, and parent-switch-managed software download and upgrades. The fabric extender supplies top-of-rack 1G copper extension with centralized Nexus parent-switch control.

Product Performance
Key Features
N2K-C2248TP-E-1GE operates as a Fabric Extender under a supported Nexus parent switch, giving engineers centralized access-port management instead of another independently managed rack switch.
The 48 100/1000BASE-T ports fit data center racks that still need 1G copper server, storage, appliance, or management connections.
The four fabric interfaces connect upstream to the Nexus parent switch using 10G SFP+ media, so optics, FET transceivers, or supported cables should be confirmed before quoting.
The 2248TP-E model provides a 32 MB shared buffer, which is one of the key reasons buyers compare it against older 2248TP variants.
Cisco lists this SKU with choice of airflow and power supply, so procurement should match port-side intake or exhaust and AC or DC power to the rack design.
Choose N2K-C2248TP-E-1GE when the buyer wants the 2248TP-E FEX profile and will confirm fabric media separately; choose N2K-C2248TF-E when the project specifically needs a FET-included bundle.
Application Scenarios
Use N2K-C2248TP-E-1GE when a rack needs 48 1G copper host ports while switching control and policy remain on a supported Cisco Nexus parent switch.
Choose this SKU when a project is expanding or standardizing Nexus 2248TP 1GE FEX deployments with the 2248TP-E model while keeping the same copper host-port profile.
Deploy N2K-C2248TP-E-1GE when procurement wants the FEX chassis ordered while leaving SFP+ optics, FET transceivers, or twinax cable selection to the final cabling design.

- Choose N2K-C2248TP-E-1GE when the buyer needs a Nexus 2248TP-E FEX and wants to confirm 10G SFP+ fabric media separately.
- Choose N2K-C2248TF-E when the project needs the 2248TP-E model with eight FET transceivers included.
- Choose N2K-C2232TM-E-10GE when host ports need 10GBASE-T instead of 1G copper.
- Do not position any Nexus 2000 FEX as a standalone switch; it must connect to a supported Nexus parent switch. Related SKU checks: N2K-C2248TP-1GE.
Selection Guide
1. Choose N2K-C2248TP-E-1GE for 1G copper FEX access
Select N2K-C2248TP-E-1GE when the project needs 48 100/1000BASE-T host ports and a Nexus parent-switch-controlled access architecture.
2. Choose N2K-C2248TF-E if FET transceivers must be included
If the quote should include Cisco Fabric Extender Transceivers with the FEX, compare N2K-C2248TF-E instead of this SKU.
3. Choose a 10GBASE-T FEX if host access needs 10G copper
If the rack has servers or appliances requiring 10GBASE-T host links, compare N2K-C2232TM-E-10GE rather than a 1G-only 2248TP-E model.
4. Verify parent switch, software, airflow, and media before ordering
Confirm parent Nexus platform, NX-OS release, 10G SFP+ fabric media, airflow direction, AC or DC power supply selection, quote, stock, lead time, warranty handling, and shipping destination.

FET Bundle Decision |
Whether N2K-C2248TF-E is a better fit |
Avoids missing FET transceivers when the buyer expects a bundle |
|
Airflow Direction |
Port-side intake or port-side exhaust |
Airflow must match the rack cooling path |
|
Power Configuration |
AC or DC power supply selection and power cord requirements |
Prevents mismatch with the rack power design |
