The WS-X4748-RJ45V+E= is a line card that is compatible with the Cisco Catalyst 4500 E-Series switches. It is designed to be inserted into the switch chassis, where it can be used to expand the number of available ports and add additional functionality to the switch.

In terms of device compatibility, the Part has 48 Gigabit Ethernet ports, which can be used to connect a wide range of devices to the network. These can include computers, servers, IP phones, wireless access points, and other networked devices.

Resiliency and High Availability

The WS-X4748-RJ45V+E= Cisco line card switch module is designed to provide high resiliency and high availability in enterprise networks.

One of the key features that contribute to the resiliency and high availability of this product is its support for redundant power supplies and redundant cooling. This means that the module can continue to operate even if one of the power supplies or cooling fans fails, which helps to minimize downtime.

The module also supports advanced features such as Cisco FlexStack, which allows you to stack multiple switches together to form a single logical switch, increasing the system's resiliency. This feature helps to minimize downtime by providing redundancy and failover capabilities.

Additionally, the module supports features like Link Aggregation Control Protocol (LACP) which increases the bandwidth by combining multiple links and improves the network resiliency by providing redundancy. Also, the Port Security feature helps to secure the port against unauthorized access and protect the network from malicious attacks.

The module also supports advanced QoS features which help to prioritize network traffic and provide high availability for critical network services such as VoIP and video.

It's important to note that, even though the module has these advanced features, it is only effective if they are properly configured and maintained. It's important to have a good network design that includes redundancy, backup, and failover mechanisms. And also to keep the software updated to ensure the highest level of resiliency and availability of the network.

It's also important to note that, as I mentioned before, this module is end of sale and end of life (EoS & EoL) which means it's no longer available for purchase and Cisco no longer provides technical support or software updates for it. So, it is important to find a suitable alternative if this module is no longer supported
