48-port Gigabit with 10G uplinks

The Cisco C1300X-48T-4X is a rackmount managed Layer 3 switch built for small and medium businesses and branch offices. It provides 48 Gigabit Ethernet RJ-45 ports plus four SFP28 uplinks running at 10 Gbps. The switch supports stacking up to eight units for a single 400-port logical system.

130.95 mpps throughput and 3 MB buffer

Wire-speed forwarding reaches 130.95 million packets per second with 64-byte frames. The 3 MB packet buffer absorbs burst traffic while jumbo frames up to 9000 bytes reduce overhead for large transfers. A 32,000-entry MAC table and 7168 IPv4 routes provide headroom for growing networks.

No Power over Ethernet support

This model does not supply PoE or PoE+ on any port. Devices such as wireless access points, IP phones or cameras will need separate injectors or a PoE-capable switch. Power draw is 66.7 W at 110 V and 72.1 W at 220 V.

Questions about this item

Will the 48 Gigabit Ethernet ports auto-negotiate with my older 100 Mbps devices?

Yes, the switch supports IEEE 802.3u 100BASE-TX Fast Ethernet, so each of the 48 RJ-45 ports will automatically negotiate 10/100/1000 Mbps speeds with legacy gear.

How can I verify the 4 SFP28 uplinks are passing 10 Gbps traffic after installation?

Log into the web UI, open the interface statistics for the four SFP28 ports and confirm the link speed shows 10 Gbps and the counters increment without CRC errors.

Does the box include SFP28 transceivers for the four 10G uplinks or must I purchase them separately?

The switch ships with the 48 RJ-45 ports ready to use; the four SFP28 uplink slots are empty and require compatible transceivers or direct-attach cables bought separately.
