Introduction

Thank you for choosing the 48-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet.. This Switch will allow you to network better than ever.. The 48-Port 10/100 + 4-Port Gigabit Switch with WebView delivers non-blocking, wire speed switching for your 10 and 100 megabit network clients, plus multiple options for connecting to your network backbone.. Forty-eight 10/100 ports wire up your workstations, while the four integrated 10/100/1000 ports connect to other switches and the backbone at Gigabit speeds.. The miniGBIC ports allow future expansion through alternate transmission media like optical fiber..

All of the 10/100 ports on the Switch support pre-standard and IEEE 802..3af standard (802..3af) Power over Ethernet (PoE) capabilities.. Each port can detect connected pre- standard and 802..3af-compliant network devices, such as IP phones or wireless access points, and automatically supply the required DC power..

The Switch can provide DC power to a wide range of connected devices, eliminating the need for an additional power source and cutting down on the amount of cables attached to each device.. Once configured to supply power, an automatic detection process is initialized by the Switch that is authenticated by a PoE signature from the connected device.. Detection and authentication prevent damage to non-PoE devices..

TheSwitchfeaturesWebViewmonitoringandconfiguration via your web browser, making it easy to manage the 256 VLANs and up to 8 trunking groups.. Or if you prefer, you can use the integrated console port to configure the Switch.. The non-blocking, wire-speed switching forwards packets as fast as your network can deliver them..

All ports have automatic MDI/MDI-X crossover detection.. Each port independently and automatically negotiates the best speed and whether to run in half- or full-duplex mode.. Head-of-line blocking prevention keeps your high‑speed clients from bogging down in lower-speed traffic and fast store-and-forward switching prevents damaged packets from being passed on into the network..

Use the instructions in this User Guide to help you connect the Switch, set it up, and configure it to bridge your different networks.. These instructions should be all you need to get the most out of the 48-Port 10/100 + 4-Port Gigabit Switch with WebView and Power over Ethernet..

SRW248G4P specifications

Cisco Systems SRW248G4P is a high-performance Layer 2 switch designed specifically for small to medium-sized businesses that require robust networking solutions. This switch supports Power over Ethernet (PoE), providing a highly flexible option for powering devices such as IP phones, wireless access points, and surveillance cameras.

One of the standout features of the SRW248G4P is its 48 10/100 Ethernet ports, which ensure ample connectivity for various networked devices. Additionally, it offers four Gigabit Ethernet uplink ports, allowing for seamless integration with existing network infrastructure and facilitating high-speed data transfer. The combination of these ports enables businesses to expand their network capabilities as needed without the immediate requirement for added devices.

The SRW248G4P comes equipped with advanced Layer 2 switching capabilities, including VLAN support, which enables the segmentation of network traffic for improved performance and security. It also supports Spanning Tree Protocol (STP) and Rapid Spanning Tree Protocol (RSTP), which help prevent network loops and ensure redundancy. With features like Link Aggregation Control Protocol (LACP), multiple physical connections can be combined into a single logical link, enhancing bandwidth and providing failover capabilities.

Another critical attribute of the Cisco SRW248G4P is its user-friendly management interface. The switch can be managed through a web-based interface, allowing IT administrators to configure settings, monitor performance, and troubleshoot issues with ease. Additionally, it supports SNMP (Simple Network Management Protocol) for integration with network management systems, further simplifying monitoring tasks.

Power over Ethernet functionality is a significant advantage of the SRW248G4P, providing up to 15.4 watts per port. This capability simplifies installation and reduces the clutter of power cords and outlets. Organizations can deploy PoE-enabled devices in locations that lack power sources, thus enhancing overall flexibility in network design.

In summary, the Cisco Systems SRW248G4P is a feature-rich switch tailored for small to medium-sized enterprises. Its blend of performance, management capabilities, and advanced features like PoE makes it a valuable asset in any organization's networking setup. By ensuring reliable connectivity and ease of management, businesses can focus more on growth and their core objectives rather than worrying about network complexities.
