In good condition and in full working order

Included
  • Dell PowerConnect 7048R 48-Port GIGABIT Layer 2 3 Managed Network Switch + 10GB
Networking 7048R, 48x 1GBase-T ports, 4 combo ports and optional dual expansion modules, ports-to-back airflow andredundant power supply/fan modules

High performance and manageable

Help meet your network switching needs, no matter how large your organization, with the Dell Networking 7048R. It features 48 ports of wire-speed L3 GbE plus robust security and enterprise management capabilities. The 7048R offers two optional flexible airflow configurations to align with front-to-back and back-to-front server installations. It also features internal hot-swap power supplies and fans to increase availability and save precious rack space. 

A USB configuration also aids in rapid deployment. Optional dedicated 64GB stacking interfaces and 10GB uplinks help you grow your switch with your network, enabling you to add 10GB without even rebooting your switch.

Stack up to 12 switches (managed as a single unit) for high-performance availability and failover deployments, including those with Dell Networking M6348 high-density 48-port I/O modules for the PowerEdge™ M1000E blade enclosure


Dell Networking 7048R Switch (Overview)

Designed for Top of Rack

The Dell Networking 7048R switches feature Energy Efficient Ethernet (EEE), multispeed fans and 80 Plus-certified power supplies to help control operating costs. Two airflow versions can be used to match your data center air circulation design to help maximize cooling efficiency. 
In addition, the internal fans, power supplies and modules are hot swappable to allow your data center to run uninterrupted while you're servicing the 7048R switches.

iSCSI optimization

Help save time when configuring your internet SCSI (iSCSi) storage area network (SAN). Dell Networking 7000 series switches automatically detect EqualLogic™ arrays and configure the switch for iSCSI environments, at both global and port levels. The 7000 series also provides information about all active iSCSI sessions to help enable easier management and optimization. 

VoIP functionality


Help ensure that voice over internet protocol (VoIP) traffic is prioritized, in the event of resource contention, through the voice VLAN function. LLDP-MED provides detailed network topology records, troubleshooting data and emergency call service via IP phone location information.
Robust management

Rapid deployment and configuration

Help save time and deployment costs by simplifying your network rollout with Dell Networking 7000 series of Gigabit Ethernet switches. Easily assign switch configuration, updates and addressing via local USB during initial rollout, or use other autoconfiguration options such as DHCP. 

Robust management


You'll enjoy a number of management options with the Dell Networking 7000 Series switches, including:
  • A powerful and industry standard CLI
  • Remote management using an embedded web server
  • Support for SNMP-based management applications
  • Up to 600 ports can be managed from single IP address in a stack of 7000 series switches

Automated security

Select from multiple security levels, with options that include such enterprise-class features as: 
  • SSH/SSL management encryption
  • DHCP snooping
  • IP and MAC-based ACLs
  • Access password protection
  • Port-based MAC address alert and lock-down
High level security is provided through: 
  • RADIUS (RFC 2865) and TACACS+ (RFC 1492) remote authentication for switch management access
  • Management access filtering via management access profiles
The Dell Networking 7000 switches also help simplify security rollouts by allowing you to try your implementation before full enforcement is enabled, helping to smooth your transition to a secure campus.
