Power and cooling considerations
The WS-C3750E-48PD-E Cisco Catalyst switch has a power supply of 750W, which is sufficient to support the switch’s PoE+ ports and other components. However, power and cooling considerations should be taken into account when deploying the switch in a network.
- Power consumption: The switch’s PoE+ ports consume a significant amount of power, and the total power consumption of the switch will increase as more devices are connected to the PoE+ ports. Administrators should ensure that the switch is connected to a power source that can provide enough power to support all connected devices and that the power supply is properly sized.
- Heat dissipation: The switch generates heat during operation, and it is important to ensure that the switch is installed in an environment that can dissipate the heat effectively. The switch should be installed in a location with adequate ventilation and air flow, and it should be kept away from heat-generating devices.
- Cooling systems: The switch should be equipped with proper cooling systems to dissipate the heat generated by the switch. Adequate air flow and proper cooling systems can help to ensure that the switch operates within safe temperature ranges.
- Temperature monitoring: The switch has a built-in temperature sensor that can monitor the temperature of the switch. Administrators should monitor the temperature of the switch to ensure that it is operating within safe ranges and make adjustments as needed.
- Redundancy: To ensure the availability of the switch, it is important to have a redundancy plan in place. This can include having a backup power supply or providing a redundant cooling system.
By taking these power and cooling considerations into account, administrators can help to ensure that the WS-C3750E-48PD-E Cisco Catalyst switch operates reliably and efficiently in a network environment.
Security and access control features
The WS-C3750E-48PD-E Cisco Catalyst switch includes a number of security and access control features to help protect your network from unauthorized access and threats.
- Access Control Lists (ACLs): The switch supports standard and extended ACLs, which can be used to control access to the network based on source and destination IP addresses, protocols, and ports.
- Network Admission Control (NAC): NAC allows you to set policies that govern which devices are allowed to access the network, based on factors such as device type, operating system, and security posture.
- Intrusion Prevention System (IPS): The switch is an IPS switch, which can help to protect your network from security threats by analyzing and blocking malicious traffic.
- Advanced Security: The switch has advanced security features such as Cisco TrustSec, which provides identity-based security and segmentation, and Cisco Identity Services Engine (ISE) which allows for identity-based network access control.
- Authentication: The switch supports various authentication methods including 802.1X, MAC Authentication Bypass (MAB), and Web Authentication (WebAuth) for access control.
- Encryption: The switch supports various encryption protocols such as IEEE 802.1AE (MACSec) and SSL/TLS for secure communication.
- Virtual private networks (VPNs): The switch supports VPN protocols such as IPsec and Secure Sockets Layer (SSL) for secure remote access.
- Firewall: The switch has stateful firewall capability to control traffic flow based on various parameters such as IP addresses and ports.
- Denial of Service (DoS) protection: The switch includes features to detect and prevent DoS attacks, which can overload and disrupt network services.
- Advanced Malware Protection (AMP): The switch supports Cisco Advanced Malware Protection (AMP) which can help detect and block advanced malware threats.
- Security Group Tagging (SGT): The switch supports Security Group Tagging (SGT) feature which allows you to assign security policies to specific users or devices.
