Description

C1000-48T-4X-L overview

The C1000-48T-4X-L is a fixed-configuration Cisco Catalyst 1000 Series managed Layer 2 access switch with 48 Gigabit Ethernet data ports and four 10G SFP+ uplinks. It is intended for small businesses, branch offices and distributed enterprise sites that need high-density wired connectivity for non-PoE endpoints.

Each access port supports 10/100/1000 Ethernet for devices such as desktops and printers. The four SFP+ uplinks support 10G fibre or direct-attach connections when fitted with suitable optics or DACs, helping connect the access layer to distribution switches, servers or another communications room.

This is a non-PoE model, so it does not provide power over Ethernet to connected devices. Projects requiring powered phones, cameras or access points should confirm endpoint power requirements before selecting a switch.

Specifications

Applications and deployment planning

The C1000-48T-4X-L suits installations where many wired devices need Gigabit access and where PoE is not required from the switch. Its fixed 1RU format is suitable for office racks, branch refreshes and replacement projects.

• Wired access for desktops, printers and other non-PoE Ethernet endpoints
• High-density access-layer deployments with 48 data connections
• 10G uplinks to distribution switching, servers or a separate communications room
• Installed-base expansion, like-for-like replacement and spare-stock requirements
• Projects using VLANs, Quality of Service, link aggregation, Spanning Tree, access control and port-security features

Uplink optics

Select SFP+ optics or DACs according to required speed, fibre type, connector, distance and the interface at the far end. Confirm whether multimode or single-mode fibre is required, and verify support at both ends before deployment.

Replacement and sourcing

When replacing an older Catalyst switch, compare port density, uplink design, VLAN and security configuration, software features and support requirements. GNTME can assist UAE buyers with model selection, optics selection, power planning, configuration planning and deployment requirements.

Frequently asked questions

Is C1000-48T-4X-L a managed switch?

Yes. It is a managed Cisco Catalyst access switch with Cisco IOS-based configuration and monitoring options.

Does C1000-48T-4X-L support PoE?

No. This model is non-PoE and its stated PoE power budget is not applicable.

What uplinks does C1000-48T-4X-L provide?

It provides four 10G SFP+ uplinks. Select optics or DACs according to speed, medium, connector, reach and the equipment at the opposite end.

Can C1000-48T-4X-L replace an older Catalyst switch?

It can often be used for replacement, but suitability depends on port density, PoE load, uplink design, VLAN and security configuration, software features and support requirements.
