Cisco 48-PORT 10/100 Stackable Ethernet POE Switch

The 48-PORT 10/100 Stackable Ethernet POE Switch from Cisco allows you to expand your network securely. It is optimized for maximum system availability, with fully redundant stacking, redundant power options, and dual images for resilient firmware upgrades. Network security is provided through IEEE 802.1Q VLANs, IEEE 802.1X port authentication, access control lists, denial-of-service prevention, and MAC-based filtering. Web-based configuration is secured using SSL. The enhanced quality of service and traffic-management features help ensure clear and reliable voice and video communications.

For wireless or voice over IP deployments, the Stackable Ethernet POE Switch supports the IEEE 802.3af standard for Power over Ethernet. Automatic load sensing in the power-control circuitry detects PoE on the end device before providing power. For safety, each port has independent overload and short-circuit protection, along with LED indicators to show power status. The Stackable Ethernet POE Switch provides 15W of available PoE power on up to 24 of the Fast Ethernet ports for powering PoE-enabled wireless access points or VoIP handsets. The maximum PoE available per switch for all ports is 360W.

The Stackable Ethernet POE Switch provides resilient stacking for up to four units, or 192 ports. A stack of units is managed as a single switch with one web management interface. The stacking capability includes master/backup unit behavior, ring and chain architecture, and hot insertion and removal of units. Software running on the switch interacts with provisioning, management, and security software on both the site's services router and the service provider's equipment. This interaction provides simple, one-step installation and access to web-administered features for the administrator and users. Simple, affordable network operations throughout the network's lifetime are the result.
