What is the operating temperature and environmental range?
Operating temperature is 32°F to 113°F (0°C to 45°C) with humidity of 10%–95% non-condensing. Designed for standard data-center and closet environments.
What are typical use cases for the Cisco Catalyst 4948-E?
Ideal for enterprise wiring closets, mid-size data center server access, and high-density Gigabit uplinks in campus LAN deployments.
How do I perform a basic VLAN configuration?
Use the IOS CLI: 1) Enter global config mode (configure terminal). 2) Create VLAN (vlan <ID>). 3) Assign ports (interface range <ports>; switchport access vlan <ID>). 4) Exit and save.
What warranty and support options are available?
Comes with a limited lifetime hardware warranty. Cisco SMARTnet and Software Application Support (SAS) contracts are available for 24/7 coverage.
How does the WS-C4948-E differ from the 4948G-E?
