C1000-48T-4G-L combines 48 copper Gigabit Ethernet data ports with four fixed 1G SFP uplinks in a managed Layer 2 switch. Non-PoE interfaces serve equipment with separate power rather than supplying endpoint power over network cables. The rack-mount 1U chassis belongs to the Catalyst 1000 family for small businesses and branch offices and uses fan cooling. C1000-48P-4G-L, a discontinued sibling, adds PoE+ with a shared 370W endpoint budget. IEEE 802.1X authentication controls network attachment, while multidomain authentication places a phone and PC on separate voice and data VLANs when they share an access port.
C1000-48T-4G-L price for new stock is $939.75, a 58.3% saving from the Cisco list price of $2,252.00. C1000-48T-4G-L refurb price is $592.20. C1000-48T-4G-L is in stock and available for free next-day delivery. (terms applied)

104 Gbps switching capacity accommodates traffic across the access and uplink interfaces. 77.38 Mpps forwarding handles 64-byte packets, providing a packet-processing measure separate from aggregate bandwidth. LACP forms aggregated links, while RSTP and MSTP handle spanning-tree operation; UDLD detects unidirectional fiber links. C1000-48T-4G-L carries 512 MB of DRAM and 256 MB of flash for operating software and configuration storage. The 16000-entry MAC table sets the address-learning limit for connected devices. Cisco Catalyst 1000 Series Switches support DHCP snooping and IP Source Guard to restrict traffic using learned or manually configured bindings. IGMP and MLD snooping direct multicast traffic toward requesting receivers. Eight egress queues per port provide traffic scheduling with priority queuing, shaping and bandwidth control. 53.66W consumption at 100% traffic provides a loaded-operation reference for electrical planning; that measurement is not an endpoint power budget or a power-supply rating.

When branch equipment and installation hardware arrive through separate purchase orders, mounting parts and regional mains cabling need individual line-item checks. RCKMNT-1RU-2KX= fits the 24-port and 48-port models, and a country-specific power cord must be selected. Specify the required mounting kit and destination power cord before the PO.
When several sites need the same segmentation template, 256 active VLANs and 4094 available VLAN IDs define different configuration limits. An approved numbering scheme can therefore exceed the permitted active inventory. Before allocating units across branches, verify each site's simultaneous VLAN requirements and include the approved configuration baseline with the purchase order.
When a staging bench must reproduce monitoring policies before equipment is issued, four SPAN sessions define the available concurrent packet-copy configurations. Multiple capture requests need an explicit session allocation rather than an assumed unlimited monitoring configuration. Include the intended monitoring configuration and console access arrangement in the order, then verify the session plan before the PO.
PoE power for connected endpoints
C1000-48T-4G-L provides data-only Ethernet ports and cannot power attached devices. C1300-48P-4G is the current 48-port PoE alternative with four 1G SFP uplinks.
10G uplinks to distribution
C1000-48T-4G-L has fixed 1G SFP uplinks, not 10G SFP+ interfaces. C1300-48T-4X is the current non-PoE alternative retaining 48 Gigabit access ports.
Two internal redundant power supplies
C1000-48T-4G-L contains one fixed power supply rather than two redundant internal supplies. A requirement for internal power redundancy rules out this hardware configuration.
Fanless operation in occupied rooms
C1000-48T-4G-L uses fan cooling and produces 31.5 dB typical sound pressure at 25°C. A requirement for completely fanless hardware excludes this model.

Uplinks stay steady and we have seen no random drops.
C1000-48T-4G-L identifies a Catalyst 1000 switch with 48 copper Gigabit data ports and four 1G SFP uplinks. C1000 names the series, 48 identifies the access-port count, T distinguishes data-only ports, and 4G identifies the uplink configuration. The complete -L PID uses the universal Cisco IOS image.
C1000-48T-4G-L is managed through Cisco Configuration Professional's on-box web UI, the CLI through an RJ-45 console or SSH/Telnet, and SNMP. An external USB Bluetooth dongle also provides browser access or SSH/Telnet CLI access from a laptop or tablet. Select the intended local or remote administration method before deployment.
C1000-48T-4G-L reached end of sale on April 30, 2025, and Cisco support ends April 30, 2030. Software maintenance and new service attachment ended April 30, 2026; vulnerability support ends April 30, 2028. C1300-48T-4G is the current replacement for new equipment purchases.
ORM Systems offers C1000-48T-4G-L new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are available for 30 days in either condition; terms apply. Cisco's Enhanced Limited Lifetime Warranty is original-owner dependent, with service ending April 30, 2030.
The Catalyst 1000 uses a single universal Cisco IOS Software image with advanced Layer 2 functionality. The hardware order therefore does not require choosing between different software images for this configuration. Keep the complete part number on the purchase order so the required port and uplink arrangement remains unambiguous.
C1000-48T-4G-L replaces WS-C2960+48TC-L, WS-C2960+48TC-L++, WS-C2960+48TC-S, WS-C2960+48TC-S++, WS-C2960R+48TC-L, WS-C2960R+48TC-S, WS-C2960L-48TS-AP, WS-C2960L-48TS-JP, WS-C2960L-48TS-LL, WS-C2960L-48TSLL++ and WS-C2960L-SM-48TS. Those predecessors reached end of sale on October 31, 2021. The replacement itself is also discontinued, so C1300-48T-4G is the current destination for a forward refresh rather than another legacy purchase.
No, C1000-48T-4G-L has data-only Ethernet ports and does not supply PoE power to connected devices. Phones, access points and other attached equipment need their own power arrangements. A powered-endpoint purchase order requires a different switch configuration rather than an additional license or an uplink accessory.
C1000-48T-4G-L provides four fixed 1G SFP uplinks. The uplink hardware is built into the chassis, so a removable network card cannot turn this variant into a 10G model. Specify compatible SFP transceivers for the intended link medium and distance, and match their speed to the 1G interfaces.
Yes, Gigabit Ethernet Catalyst 1000 switches support Single IP Management for eight connected switches. Normal uplink ports carry the inter-switch connections, so these links must be included in the uplink plan. The feature provides management grouping through one address and does not apply to Fast Ethernet models.
C1000-48T-4G-L is a 1U rack-mount switch compatible with RCKMNT-1RU-2KX=. The chassis measures 443.992 mm wide, 288.036 mm deep and 43.942 mm high, with a weight of 3.95 kg. Confirm the required mounting hardware and country-specific power cord on the purchase order before installation.
No, C1000-48T-4G-L has one fixed power supply rather than redundant internal supplies. Adding another internal PSU is not a configuration option for this chassis. If the purchase requirement includes two internal supplies, select different hardware rather than treating the missing redundancy as an accessory-order issue.
No, C1000-48T-4G-L uses fan cooling, with 31.5 dB typical sound pressure at 25°C ambient. Fanless operation elsewhere in the Catalyst 1000 family does not describe this 48-port configuration. For equipment installed near occupied work areas, assess the stated acoustic behavior before specifying this model.
C1000-48P-4G-L adds PoE+ endpoint power with a shared 370W budget, while C1000-48T-4G-L has data-only ports. Both provide four 1G SFP uplinks and both are discontinued. The PoE version fits existing powered-endpoint installations; the data-only version fits replacements where attached equipment already has its own power.
C1000-48T-4X-L supplies four 10G SFP+ uplinks, whereas C1000-48T-4G-L supplies four 1G SFP uplinks. Both are discontinued non-PoE variants with 48 Gigabit access ports. The 4X model fits existing installations requiring faster distribution links; the 4G model fits replacements where 1G uplinks remain a requirement.
C1300-48T-4G is the current replacement for discontinued C1000-48T-4G-L, rather than an uplink-speed upgrade. Both configurations provide 48 Gigabit data ports and four 1G SFP uplinks. Existing hardware-standard replacements point to the legacy model; new rollout purchase orders should specify the current Catalyst 1300 replacement.
