Small Business Access for Locally Powered Copper Endpoints

WS-C2918-48TT-C is a managed Layer 2 access switch with 48 10/100Mbps Ethernet ports and two fixed Gigabit copper uplinks. The non-PoE, 1U configuration belongs to the Cisco Catalyst 2918 family and runs the Chinese LAN Lite image. Access connections remain Fast Ethernet even when the uplinks operate at Gigabit speed. The discontinued WS-C2918-48TC-C differs by offering dual-purpose copper/SFP uplinks rather than copper-only connections. This configuration is therefore a legacy replacement option for locally powered endpoints, not a Gigabit desktop upgrade.

Technical Details

16 Gbps switching capacity handles aggregate switched traffic, while 10.1 Mpps forwarding applies to 64-byte packets. WS-C2918-48TT-C has 64 MB DRAM, 32 MB flash, and an 8000-entry MAC address table. Cisco IOS supports LACP link aggregation, PVST+, BPDU guard, and port security for controlling access and Layer 2 topology. Four output queues per port provide traffic prioritization. The chassis uses internal AC power and fan cooling; an external RPS connection is not available.

Ordering

ORM Systems offers WS-C2918-48TT-C new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, PSU status, and fan status, with firmware verified and configuration wiped to factory default. Specify condition and quantity on the PO: new units carry up to a 3-year extended ORM warranty, certified refurbished units up to 1 year, and returns are 30 days on every condition; terms apply. Cisco service ended October 31, 2020. For enterprise and volume orders, PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US, and MEA are available.

Buying Notes

Buying NotesKey Specs

End-of-sale ordering boundary

WS-C2918-48TT-C reached end of sale on October 22, 2015. Treat new sealed units as legacy inventory, and specify the condition explicitly rather than assuming continuing factory production.

Power-cycle failure risk

WS-C2918-48TT-C may fail to boot after a power cycle if affected memory components degrade. Additional reboots do not recover that failure, so avoid simultaneously power-cycling an entire installed group.

Best For

Chinese-Language Standardization

Existing sites using Simplified Chinese operating conventions may require matching front-panel labels and a Chinese graphical interface. Treat language as a hardware-standard requirement rather than selecting a replacement solely by interface count. Confirm that the ordered configuration matches the site's operating conventions before issuing the PO.

Lab Segmentation

A lab or staging purchase with multiple isolated networks needs a VLAN plan before hardware selection. The series supports 64 VLANs and 64 spanning-tree instances. Separate the proposed test segments from production requirements, and check the planned active VLAN count before specifying the staging order.

Branch Cabling Review

A branch replacement using existing copper cabling needs a link-length and cable-category check before the hardware order. Copper connections are limited to 100 meters, and Gigabit connections require four-pair Category 5 or higher cabling. Record cable remediation separately from the switch quantity before submitting the PO.

Not Suitable If

Gigabit speed at every desktop

Access interfaces stop at 100Mbps; Gigabit capability belongs to the uplinks. A requirement for Gigabit workstation connections needs a different access-port configuration.

Direct fiber uplinks

The uplinks use copper RJ-45 connections, with no SFP cages or removable network-module bay. Fiber connections cannot terminate directly on this configuration.

Ethernet power for attached endpoints

The access ports do not supply PoE. Phones, cameras, or access points requiring Ethernet-delivered power need separate endpoint power or a PoE-capable switching configuration.

Questions & Answers

What does WS-C2918-48TT-C identify?

WS-C2918-48TT-C identifies the Catalyst 2918 configuration with 48 Fast Ethernet access ports and two copper Gigabit uplinks. The 48 portion identifies access-port density, while the TT configuration distinguishes copper-only uplinks from the TC dual-purpose variants. The complete PID identifies a Chinese LAN Lite model.

How is WS-C2918-48TT-C managed?

WS-C2918-48TT-C supports a browser-based device manager, Cisco IOS CLI through the console or remote Telnet/SSHv2, CiscoView, and SNMP management. These are separate management paths, so an operational plan should identify the intended configuration interface and monitoring application rather than assume browser access is the only option.

Is WS-C2918-48TT-C discontinued?

WS-C2918-48TT-C is discontinued: Catalyst 2918 sales ended October 22, 2015, and Cisco support ended October 31, 2020. A purchase is therefore for legacy inventory rather than an actively supported Cisco product. Keep hardware condition and supplier coverage separate from the manufacturer's ended service lifecycle.

What conditions and warranties does ORM Systems offer for WS-C2918-48TT-C?

WS-C2918-48TT-C is offered new sealed or certified refurbished. ORM provides up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Returns are 30 days on every condition; terms apply. Cisco's original Limited Lifetime hardware coverage ended with support on October 31, 2020.

Does WS-C2918-48TT-C provide PoE?

No, WS-C2918-48TT-C does not supply PoE to attached devices. Endpoint power must be arranged separately from the Ethernet data connection. For a replacement purchase, distinguish devices with local power from devices that depend on power delivered through their network cable before approving the configuration.

Which uplinks does WS-C2918-48TT-C provide?

WS-C2918-48TT-C provides two fixed 10/100/1000BASE-T copper uplinks, not SFP uplinks. No optical transceiver is installed or required for those connections. Match the upstream connection medium when specifying replacement hardware, and do not include SFP optics on the assumption that every Catalyst 2918 variant accepts them.

Which software image does WS-C2918-48TT-C use?

WS-C2918-48TT-C uses the Chinese LAN Lite image on Cisco IOS. The software identity is part of the complete configuration, not just the physical interface count. Keep the image requirement alongside the full part number in a replacement order instead of specifying only the Catalyst family name.

Can the Catalyst 2918 switch be rack-mounted?

Yes, the Catalyst 2918 switch is a full-width 1U rack-mount chassis. Rack installation requires the appropriate mounting hardware. For a legacy replacement order, identify the mounting requirement and confirm the hardware supplied with the chosen condition rather than treating a bare chassis as a complete installation package.

What is the difference between WS-C2918-48TT-C and WS-C2918-48TC-C?

WS-C2918-48TC-C has two dual-purpose copper/SFP uplinks, whereas WS-C2918-48TT-C has copper-only uplinks. Both models are discontinued. The TT model fits an existing copper-uplink replacement requirement; the TC model fits a legacy configuration requiring selectable copper or fiber connections, with each dual-purpose uplink using only one medium at a time.

What is the difference between WS-C2918-48TT-C and WS-C2918-24TT-C?

WS-C2918-48TT-C has 48 Fast Ethernet access ports, while WS-C2918-24TT-C has 24. Both models are discontinued and use two copper Gigabit uplinks. The 48-port model fits the higher-density legacy replacement requirement; the 24-port model fits a replacement where the smaller access-port count matches the installed design.

Can WS-C2918-48TT-C fail after a power cycle?

Yes, affected WS-C2918-48TT-C units can fail to boot after a power cycle because of degraded memory components. The failure can produce no console response and is not recovered by another reboot. Plan restart activities accordingly rather than removing power from an entire installed group simultaneously.
