Performance of Chassis Fan

The WS-C4503-E Cisco Catalyst 4500 E-Series Chassis is a modular switch that is designed for enterprise-class access and distribution layer deployments. The fan performance in this switch refers to the operation and efficiency of the fans used to cool the internal components of the switch. The fans help to dissipate heat generated by the switch, and their proper operation is critical for maintaining the overall health and performance of the switch. This product has two redundant power supplies, and the fans are connected to power supply, so the switch can continue to operate even if one of the fans fails.


The WS-C4503-E Cisco Catalyst 4500 E-Series Chassis is a high-reliability fan system designed to provide optimal cooling and airflow for the Cisco Catalyst 4500 E-Series switch. The fan system is designed to operate in high-temperature environments and features redundant fans to ensure continuous operation even in the event of a fan failure. The fan system is also designed to be easily serviceable, allowing for quick and easy replacement of failed fans. Additionally, the fan system is designed to minimize noise and vibration, providing a quiet and stable operation.

Compliant Standards

Compliant standards refer to a set of guidelines and regulations that this part Cisco Catalyst 4500 E-Series 3 Slot Chassis Fan must adhere to in order to meet industry standards for performance, safety, and compatibility with other equipment in the network. These standards are set by organizations such as UL, IEC, RoHS, and FCC, among others.

UL 60950-1 is a safety standard for information technology equipment, including servers and switches. It specifies requirements for electrical safety, environmental safety, and fire safety. This ensures that the fan is safe to use and poses no risk of electrical hazards or fires.

IEC 60950-1 is an international version of the UL 60950-1 standard. It is equivalent to the UL standard, but is recognized globally, which means it can be used anywhere in the world.

RoHS stands for Restriction of Hazardous Substances, and it is a European Union directive that limits the use of certain hazardous materials in electronic products. This ensures that the fan is environmentally friendly and poses no risk to the environment.

EN 55022 is a standard for electromagnetic compatibility (EMC) that specifies limits on the levels of electromagnetic interference (EMI) that electronic equipment can generate. This ensures that the fan does not interfere with other electronic equipment in the network and does not emit harmful levels of EMI.

EN 55024 is a standard for immunity to electromagnetic interference, specifying limits on the levels of EMI that electronic equipment can tolerate. This ensures that the fan can operate in environments where there is already a high level of EMI without being affected.

EN 55032 is a standard for radio frequency interference (RFI) that specifies limits on the levels of RFI that electronic equipment can generate. This ensures that the fan does not interfere with radio communication in the network and does not emit harmful levels of RFI.

FCC Part 15 Class A is a standard for electromagnetic interference (EMI) that specifies limits on the levels of EMI that electronic equipment can generate. This ensures that the fan does not interfere with other electronic equipment in the network and does not emit harmful levels of EMI.

Different Types of Switches

Networking switches vary widely depending on the number of devices they can support, network bandwidth/speed, and form factor. Switches for small offices will have anything between 4 and 8 ports and can fit on a desk. For larger office network implementation, switches may have 24 ports, 48 ports, 96 ports, and 128 ports and are rack-mountable between 1U and 4U. Switches come in different types depending on the network speed and tasks they support. These include 40/100 Gbps, 10 Gigabit (up to 10000 Mbps), Gigabit Ethernet (up to 1000 Mbps), Power over Ethernet, and Fast Ethernet (10/100 Mbps).

Unmanaged Switches

The unmanaged switches offer fixed configurations on a plug-and-play basis. It is the most basic switch and there are a few choices in the market. These switches are affordable, but the basic features make them inappropriate for enterprise applications.

Managed Switches

The number of features and level of functionality improves with managed switches, making them ideal for enterprise and business applications. These switches are built with the command-line interface for ease of configuration. Equally, they support SNMP agents that come in handy when troubleshooting network issues.

The security on managed switches is better and will protect different types of traffic. Other features include support for virtual LANs, IP routing, and quality of service settings. Managed switches are more expensive compared to all other types of switches.

Smart Switches

Smart switches refer to switches that possess more features than those unmanaged switches but do not have the full features of managed switches. Smart switches are more cost-effective than managed switches.

Some of the limitations of the smart switches are a lack of telnet access support, Web GUIs, and a lack of many features for VLANs. They are affordable compared to a fully managed switch and are suitable for a smaller computer network.

Modular Switches

Modular switches allow the addition of expansion modules as the network expands. The expansion modules allow for more networked devices but are application-specific. They may include wireless access points, firewalls, or network analysis tools. The flexibility of a modular networking switch comes at a higher cost.
