In terms of flexibility, the SG500-28 offers two combo ports that support both RJ-45 connections and Small Form-Factor Pluggable (SFP) modules, plus two dedicated SFP slots for 1G/5G fiber connections, enhancing the switch's adaptability to various network architectures. This feature allows for easy network expansion and integration of fiber-optic connections for long-distance data transmission.
The switch's hardware is designed to support a large volume of data, with a MAC table capable of holding up to 16,000 addresses, facilitating efficient network resource management and security. VLAN support is extensive, with the device capable of managing up to 4,096 VLANs, allowing for sophisticated network segmentation and improved traffic management. The SG500-28 also supports jumbo frames up to 9K bytes, enabling the efficient handling of large data packets and reducing the overhead associated with processing multiple smaller packets.
Key hardware specifications include:
- Reset button for easy device resetting without the need for additional tools or software.
- LED indicators for system status, master operation, stack ID, and individual link/speed status for each port, providing at-a-glance monitoring of network activity and performance.
- Flash memory of 256 MB and CPU memory of 512 MB, coupled with a packet buffer of 4 MB, ensuring smooth operation and efficient data processing.
Physically, the SG500-28 measures 440 mm in width, 44 mm in height, and 257 mm in depth, with a weight of 3.4 kg, making it suitable for standard rack mounting in data centers or network closets. The device operates reliably within a temperature range of 0 °C to 40 °C and can be stored in temperatures ranging from -20 °C to 70 °C. Humidity tolerance is maintained from 10% to 90% (non-condensing) for both operating and storage conditions, ensuring durability in varied environmental conditions.
Noise levels are kept low, with acoustic noise measured at 35 dB in temperatures up to 30°C, increasing to 51.7 dB at 50 °C, ensuring a relatively quiet operation suitable for office environments. The SG500-28 boasts a Mean Time Between Failures (MTBF) of 248,842 hours, highlighting its reliability and durability.
Each unit comes with essential accessories for immediate setup, including a power cord, mounting kit, quick start guide, and console cable, facilitating a straightforward installation process.
The Cisco SG500-28 stands out as a versatile and efficient solution for businesses seeking to enhance their network infrastructure with a reliable, high-performance switching solution.
