Description
Power and Cooling Considerations
The Cisco Nexus C1-N3K-C3548X switch is a high-performance Ethernet switch designed for use in data centers, campus networks, and other high-traffic environments. Power and cooling considerations are important when deploying this switch to ensure optimal performance, reliability, and energy efficiency.
Power Considerations:
- The C1-N3K-C3548X switch requires a dual-power supply configuration, which provides redundancy and helps ensure uninterrupted operation in case of a power supply failure.
- The switch has a maximum power consumption of 490 watts, which means that the power supply units must be able to provide at least this amount of power. It is also important to ensure that the power source to which the switch is connected can provide sufficient power to support the switch and other devices that may be connected to it.
- The switch supports several power-saving features, including Energy Efficient Ethernet (EEE), which can help reduce power consumption during periods of low network activity. The switch can also be configured to enter power-saving modes when not in use.
Cooling Considerations:
- The C1-N3K-C3548X switch is designed to be rack-mounted and has a fan tray that provides cooling to the internal components. It is important to ensure that the switch is installed in a well-ventilated area to ensure adequate airflow to the fan tray.
- The switch has a maximum operating temperature of 104°F (40°C). It is important to ensure that the ambient temperature in the switch’s location does not exceed this limit, as this could cause the switch to overheat and potentially fail.
- The switch is designed to operate in a data center environment, which typically provides air conditioning and other cooling systems to maintain a stable temperature. In other environments, it may be necessary to provide additional cooling to ensure optimal switch performance and reliability.
Security and Compliance Features
The Cisco ONE Nexus C1-N3K-C3548X Ethernet Switch is a high-performance, low-latency switch designed to support modern data center requirements. It comes with various security and compliance features, some of which are highlighted below:
- Secure Boot: This feature ensures that only digitally signed images are loaded on the switch during the boot process, thereby preventing the installation of unauthorized firmware.
- TrustSec: This is a security solution that provides secure access to network resources using role-based access control (RBAC) and identity-based networking.
- MACsec: This feature provides point-to-point encryption of data on a per-link basis, protecting data confidentiality and integrity.
- SNMPv3: Simple Network Management Protocol (SNMP) version 3 provides secure access to network devices for monitoring and management purposes.
- ACLs: Access Control Lists (ACLs) enable administrators to define policies for traffic filtering and shaping to protect against unauthorized access and other security threats.
- DHCP Snooping: This feature provides security against rogue DHCP servers by intercepting DHCP messages and filtering out unauthorized ones.
- Port Security: This feature restricts unauthorized access to the network by limiting the number of MAC addresses that can be learned on a particular port.
- Compliance: The Cisco ONE Nexus C1-N3K-C3548X Ethernet Switch complies with various industry standards and regulations such as PCI DSS, HIPAA, and FIPS 140-2.
Port Configuration and Management
The Cisco ONE Nexus 48 port Ethernet switch, also known as the C1-N3K-C3548X, is a high-performance switch that provides reliable connectivity for enterprise networks. It offers advanced features and functionalities that enable network administrators to manage and configure their networks with ease.
Port Configuration:
The C1-N3K-C3548X switch has 48 Ethernet ports that support various speeds ranging from 10/100/1000 Mbps to 10 Gbps. The ports are located on the front panel of the switch and are labeled numerically from 1 to 48. Each port can be configured individually or in groups using the command line interface (CLI) or graphical user interface (GUI).
The switch also supports VLANs, which can be configured to segment the network and provide security and performance benefits. The switch supports both traditional VLANs and Virtual Extensible LANs (VXLANs) that enable network administrators to scale their networks beyond traditional VLAN limits.
Management:
The C1-N3K-C3548X switch provides various management options that enable network administrators to manage and configure their networks effectively. These include:
- Command Line Interface (CLI): The switch provides a CLI that enables administrators to configure the switch using command-line commands.
- Graphical User Interface (GUI): The switch has a web-based GUI that provides an easy-to-use interface for managing and configuring the switch.
- Simple Network Management Protocol (SNMP): The switch supports SNMP, which enables administrators to monitor and manage the switch remotely.
- Cisco Prime Infrastructure: The switch can be integrated with Cisco Prime Infrastructure, which provides a centralized management platform for network devices.
