Overview
The Cisco SG300-52-K9 is a managed switch designed to support a high-performance network infrastructure. It features a total of 52 Gigabit Ethernet ports, including 50 RJ-45 ports and 2 combo ports that support both RJ-45 and SFP (Small Form-Factor Pluggable) connections. This flexibility allows for a wide range of connections, from copper to fiber, depending on the networking requirements.
The switch has a forwarding rate of 77.38 Mpps (Million Packets per Second) and a switching capacity of 104 Gbps (Gigabits per Second), ensuring efficient handling of traffic even in demanding situations. It supports a MAC (Media Access Control) address table of 16K addresses, allowing for extensive device connectivity across the network. The SG300-52-K9 is capable of handling up to 4,096 VLANs (Virtual Local Area Networks), providing the versatility needed for segmenting networks into distinct, manageable sections.
One of the notable features of this switch is its support for jumbo frames up to 9K bytes, which enhances data flow efficiency across the network by allowing larger packets to be transferred. The unit includes a reset button, and its front panel is equipped with multiple LEDs indicating system status, link/activity, speed, PoE (Power over Ethernet), and an LED power-saving option.
The hardware specifications reveal a switch built for durability and performance. It has 16 MB of flash memory and 128 MB of CPU memory, with a dual 8 Mb packet buffer to ensure smooth data transmission. The device's dimensions are 440 x 44.45 x 257 mm, and it weighs 3.91 kg, making it suitable for standard rack mounting in data centers and network closets.
Operating conditions are broad, with the switch functioning optimally between 0 °C and 50 °C. It can be stored in temperatures ranging from -20 °C to 70 °C. Relative humidity tolerance during operation ranges from 10% to 90% (non-condensing), ensuring reliability in a wide array of environmental conditions. The SG300-52-K9 has an acoustic noise level of 40.1 dB, minimizing noise in workspaces. Its Mean Time Between Failures (MTBF) is 206,005.6 hours, indicating a reliable long-term operation.
Included with the switch are essential accessories for immediate setup and use. These include a power cord, mounting kit, serial cable, and a CD-ROM containing user documentation. A quick start guide is also provided to facilitate easy installation.
