48-Port 10/100Mbps Stackable Managed Switch Cisco SF500-48

- Product ID Number: SF500-48-K9

- 48-port 10/100Mbps Stackable Managed Switch with Gigabit Uplinks.

- The SF500-48 delivers a solid foundation that will work for your current and future business applications. The SF500 delivers true stacking capabilities, advanced security, quality of service, energy-saving technology (EEE), IPV6, and network features to give you of the reliability and performance you need.

The Cisco SF500-48 switch features include:

- Stackable

- Managed

- 48 10/100 ports

- Four Gigabit Ethernet ports consisting of:

o 2 combination ports

o 2 Small Form-Factor Pluggable (SFP) ports

Cisco SF500-48 Benefits and Features

- Easy to Deploy:

o Can be remotely managed

o Includes a Textview command-line interface

o Features Cisco Configuration Assistant

o Delivers automated deployment tools

- Reliability and resiliency:

o True stacking capabilities

o Dual images

o Advanced redundancy protocols

- True stacking: Cisco 500 Series switches allow you to manage and configure multiple switches in a stack, all with a single IP address.

- Strong security:

o Ability to use access control lists (ACLs)

o Create guest virtual LANs (VLANs)

o Management data is encrypted

o IEEE 802.1X port security

o Other advanced network defense features

- Advanced IP telephony support: Cisco SF500-48 switches can auto-configure compatible connected IP phones with the desired VLAN and quality of service (QoS) parameters. This delivers properly prioritized network traffic.

- Power over Ethernet Plus (PoE+): Supports PoE+ to deliver up to 30 watts over each port, which can power PoE-enabled devices such as IP phones.

- Traffic management: The Cisco SF500-48 can support static Layer 3 routing capabilities

- IPv6: The Cisco SF500-48 has received the USGv6 and IPv6 Gold certification.

- Power efficiency: Cisco 500 series switches will utilize low-power chipsets, fanless designs, and other “green” features that reduce power consumption and enable quieter operation.

- Expandability: The SF200-48 features expansion slots.
