The Cisco Catalyst C1300-24XTS is a fixed-configuration 1U switch with an internal AC-to-DC power supply and a centrifugal blower, according to the teardown in ServeTheHome’s review. The reviewers also identified Marvell and Lattice components inside. For rack planning, LavX News, citing ServeTheHome, reports 12 copper 10GBASE-T ports, 12 SFP+ cages, a separate management port, and a single AC inlet.
For installation planning, account for the reported mix of copper and SFP+ connections, the separate management port, and the single AC inlet.
Inside the 1U chassis
ServeTheHome describes a main circuit board spanning the front of the chassis, with the power supply at the rear left and the blower at the rear right. The review also notes small heatsinks on the SFP+ cages.
The layout identifies the main building blocks, but the practical takeaway is simple: the switch uses active airflow and an internal power supply in its 1U chassis.
The Marvell and Lattice parts
The teardown identifies a Marvell 88X3580-DGQ4, an eight-port 10GBASE-T PHY. A PHY, or physical-layer transceiver, handles the signaling for a network connection. ServeTheHome says this component supports 802.3an, 802.3bz/NBASE-T, and 802.3az Energy Efficient Ethernet. The review also identifies a neighboring four-port Marvell unit, without mapping either component to a specific external port group.
The switch’s identified Marvell Prestera parts are 98DX4504A1 and 98DX2530A2. The teardown also identifies a Lattice LCMXO2-1200UHC programmable-logic device from the MachXO2 family. These component identifications describe the hardware found inside; they do not by themselves indicate how the switch performs under a particular workload.
What the blower observation says
ServeTheHome’s reviewers described the blower as slightly louder than other switches they had tested. That is a qualitative comparison, not a measured noise level. The review describes one centrifugal blower in the chassis.
Ports and power for rack planning
LavX News, citing ServeTheHome, reports 12 independent copper 10GBASE-T ports and 12 SFP+ cages. The reported chassis dimensions convert to approximately 17.5 × 10.75 × 1.73 inches, and its reported weight converts to about 9.3 pounds.
The same account describes a dedicated 1GbE RJ45 out-of-band management port, separate from the data ports and console connection. It also reports a console connection that includes USB-C. For power, it describes one AC inlet and no redundant power input; an A+B power arrangement would require an external automatic transfer-switch PDU.
