Fanless. The Cisco Catalyst Switches of the 1000 series are fixed managed Gigabit Ethernet Layer 2 switches designed for small businesses and branch offices. They are simple, flexible, and secure switches that are ideal for out-of-the-wiring environments and critical Internet of Things (IoT) implementations. The Cisco Catalyst 1000 switches run on Cisco IOS software and support easy device and network management via a command-line interface (CLI) as well as an on-box web user interface. These switches provide small businesses with enhanced network security, network reliability, and operational efficiency. The Cisco Catalyst Switches of the 1000 series are available in 8, 16, 24, or 48 Gigabit Ethernet port variants with and without PoE ports. They feature 2 or 4 fixed 1-Gigabit Ethernet SFP/RJ45 combo uplink ports or 4 fixed 10-Gigabit Ethernet SFP uplink ports. The PoE-supported models have a power budget of up to 740 W. Security features include 802.1X support for connected devices, Switched Port Analyzer (SPAN), and Bridge Protocol Data Unit (BPDU) Guard. There are also compact fanless models available with a depth of less than 33 cm. Device management supports over-the-air access via Bluetooth, SNMP (Simple Network Management Protocol), RJ-45, or USB console access, significantly simplifying management and configuration. These switches offer high reliability thanks to a higher MTBF (Mean Time Between Failures) and improved support with a limited lifetime warranty (E-LLW).
