Popis produktu: NETGEAR Stackable, PoE Managed Gigabit Switches GSM7228PS and GSM7252PS allow the most flexible and easy-to-deploy Gigabit Power over Ethernet infrastructure. All the 24 and 48 ports of 10/100/1000 Mbps interfaces support 802.3af PoE standard with a comfortable 384 Watts total budget. The first 8 ports support high power 802.3at PoE+, with up to 30 Watts per port. Four (SFP) Gigabit interfaces provide optional fiber connectivity for longer reach Gigabit Ethernet requirements. Two built-in 10 Gigabit Ethernet SFP+ interfaces on the front and two additional 10 Gigabit module bays on the rear, permitting both uplinks and local/distant stacking, provide versatile 10 Gigabit deployment possibilities.

Enterprise-class L2+

Combining superior resiliency, enterprise-class security and non-blocking performance, NETGEAR Stackable PoE Managed Gigabit Switches GSM7228PS and GSM7252PS offer a full set of Layer 2 management features, as well as Layer 2+ (Layer 3 lite - IPv4 routing) with unsurpassed affordability. Together with VLAN routing, voice-class prioritization, and chassis-like stack even with local or distant non-PoE Layer 3 Gigabit Managed Switches GSM7328S / GSM7352S / GSM7328FS, the GSM7228PS and GSM7252PS series can be deployed at enterprise edge, remote branch offices and closer to the core of small and medium businesses' growing networks.

L3 Scalability

Layer 3 license upgrades GSM7228PL and GSM7252PL unlock IPv4/IPv6 dynamic routing capabilities of GSM7228PS and GSM7252PS. Designed for Enterprise networks and core/aggregation levels of SMB networks, L3 upgraded GSM7228PS and GSM7252PS provide advanced routing protocols such as OSPF, VRRP and multicast for converged applications.

High Availability

NETGEAR Stackable, PoE Managed Gigabit Switches GSM7228PS and GSM7252PS come with a removable power module for the main power supply. In the event of a power supply failure, the switch can immediately shift to an external RPS device while the internal power module is replaced for 100% uptime. Like all NETGEAR ProSafe Managed Switches, the GSM7228PS and GSM7252PS are backed by the NETGEAR ProSafe Lifetime Warranty.
