Overview of the WS-C2948G-L3 Cisco Catalyst Switch
The WS-C2948G-L3 is a Cisco Catalyst switch that belongs to the 2948G-L3 series. This switch is a Layer 3 switch which means it can perform routing functions. It has 48 10/100 ports and 4 Gigabit Ethernet uplink ports, as well as a power supply of 150W. It is designed for use in enterprise LAN access and distribution environments. The switch supports Cisco's EnergyWise technology, which helps lower energy consumption, and also includes advanced security features, Quality of Service (QoS) capabilities and Layer 3 routing features. Additionally, the switch is stackable, allowing for up to 9 switches to be connected together for easy management and expansion. The WS-C2948G-L3 is a versatile switch suitable for a wide range of enterprise networking needs where routing capabilities are required.
Power and cooling considerations
The WS-C2948G-L3 Cisco Catalyst switch has a number of power and cooling considerations that need to be taken into account when deploying and maintaining the switch:
- Power supply: The switch requires a single power supply, and it can be configured with an optional redundant power supply for added reliability.
- Power consumption: The switch has a maximum power consumption of 140W, and it can be configured with Cisco EnergyWise technology to help lower energy consumption and reduce power costs.
- Cooling: The switch is designed to operate in a temperature range of 32 to 104°F (0 to 40°C) and has a built-in cooling fan to dissipate heat.
- Ventilation: Adequate airflow is required to ensure the switch operates within the specified temperature range, and it should be installed in a location with good ventilation to ensure proper cooling.
- Power over Ethernet (PoE): The switch does not support Power over Ethernet (PoE), so if you need to power devices like IP phones or wireless access points, you will need to use separate power supplies or PoE injectors.
- Power redundancy: The switch can be configured with a redundant power supply for added reliability.
- Environmental monitoring: The switch has a built-in temperature sensor that can be monitored remotely via SNMP, allowing administrators to track and respond to any changes in temperature.
- Energy efficient Ethernet (EEE): The switch supports Energy Efficient Ethernet (EEE) which can help to reduce power consumption when the switch is not transmitting or receiving data.
Stackable design and stacking capabilities
The WS-C2948G-L3 Cisco Catalyst switch supports a stackable design, which allows multiple switches to be connected together to form a single logical unit. This can make it easier to manage and expand the network, as well as provide redundancy and failover capabilities.
- StackWise Technology: The switch supports StackWise technology, which allows up to nine switches to be connected together in a stack, providing redundancy and failover capabilities at the stack level.
- Single IP management: When the switches are stacked together, they can be managed as a single unit, simplifying network management and reducing configuration errors.
- Redundant stackwise links: The switch supports redundant stackwise links, which can help to ensure that the stack remains operational even if one of the stackwise links fails.
- Stackwise bandwidth: The switch has a stackwise bandwidth of 80Gbps, which allows for high-speed communication between the switches in the stack.
- Automatic StackWise Configuration: The switch supports automatic StackWise configuration, which allows the switch to automatically detect and configure the stackwise links.
- StackWise failover: The switch supports StackWise failover, which allows for automatic failover in case of a switch failure within the stack.
- Stack-level redundancy: The switch supports stack-level redundancy, which allows for a standby switch to take over the functions of a failed switch, ensuring that network services remain available.
