Cisco SF220-24PK9

Cisco SF220-24PK9 is a smart switch that is designed for small and midsize organizations. It shows great performances and management systems, high-security levels, and scalability.  They provide a strong network connection through various comprehensive features. It drew a power supply of 21.1 Watts whereas the AC input power required is 100 to 240 Volts AC with 50/60 Hz. The needed PoE power budget is 180 W and the PoE per port requirement is 30 W. It has a Random Access Memory (RAM) of 128 MB and flash memory of 32 MB. In addition, Jumbo frames are supported which are Ethernet frames of 9216 Bytes of payload to enhance the capacity. The MAC address table size covers 8192 entries. The forwarding rate is 6.55 Mpps of 64 bytes packet size with a switching bandwidth of 8.8 Gb per second. The available packet buffer size is 4.1 MB.

There are 24 10/100 Mb per second Ethernet RJ45 PoE and 2 10/100/1000 Mb per second Gigabit Combo of Ethernet and Uplink ports in SF220-24PK9. The number of supported protocols includes IPv4 and IPv6, MAC filtering, Link aggregation, Head of Line (HOL) Blocking, and IGMP Snooping. It supports various standards of IEEE which include IEEE 802.1d, 802.1s, 802.3x, 802.3ad, 802.3, 802.3z, 802.3at,802.3af, 802.1w, 802.3u, and many more. However, the Request for Comments (RFC) standards include RFC 768, 793, 879, 894, 922, 1042, 1123, 1157, 1981, 2460, 2666, 4443, 4862, and others. Indicator lights are used in order to inspect the status of system activation, identify the speed, checking the links and activities. When the switch is in the active state, the noise level will be 42.9 dB which is not too high or low.

Each system needs a specific temperature in its surroundings to work smoothly and swiftly. In order to maintain that temperature, any fan cooling system is preferred for the device. However, the range of operating temperature that is acceptable by the device is 0 degrees to 50 degrees Celsius with an operating humidity between 10% to 90%. Similarly, the storage temperature ranges from -20 degrees to 70 degrees Celsius with a storage humidity between 10% to 90%. While measuring the dimensions, it shows that the width is equal to 17.3 inches, depth is 9.84 inches, and height is 1.7 inches. The total weight measured is 8.02 lbs. which is equivalent to 3.64 kgs only. It has a certification from many certification listing marks including Federal Communications Commission (FCC), CE mark, UL listing mark, C-Tick, Canadian Standards Associations (CSA), as per the manufacturers.

Security always remains the most important factor in every device. The transmission of data throughout the network should be secure enough that any unauthorized user cannot access the data traffic flow. Thus, some of the high-security features have been added which comprises Denial of Service (DoS) attack prevention, Remote Authentication Dial-In User Service (RADIUS) authentication, and Storm control feature. In addition, it also supports 1, 2c, and 3 Simple Network Management Protocols (SNMP). These networking protocols monitor and manage all the connected devices in a network. It is a complete package of multiple features in one switch. So, avail all of these amazing features in one switch at an affordable price.
