Cisco Catalyst 4948E Ethernet Switch - 48 Ports - Manageable - Refurbished - 3 Layer Supported - Twisted Pair - 1U High - Rack-mountable, Desktop - 90 Day Limited Warranty - RoHS-6 Compliance WS-C4948E-S-RF

Cisco Catalyst 4948E Ethernet Switch - 48 Ports - Manageable - Refurbished - 3 Layer Supported - Twisted Pair - 1U High - Rack-mountable, Desktop - 90 Day Limited Warranty - RoHS-6 Compliance

The Cisco Catalyst 4948E and 4948E-F build on the advanced technology of the Cisco Catalyst 4948 Switches, the most widely deployed ToR switch in the industry, with more than 10 million ports deployed worldwide. The Cisco Catalyst 4948E and 4948E-F double the uplink bandwidth and offer true front-to-back and back-to-front airflow with no side or top venting. The airflow direction is controlled by the changing of fans. Optional front-to-back and back-to-front airflow management reduces data center operating costs by providing strict hot-aisle and cold-aisle isolation.
