Introduction
The ES7528 is a rack mount high-port density managed PoE switch designed exclusively for highly critical
PoE applications such as real-time IP video surveillance with high-resolution quality and evolving wireless
communication systems such as Wimax and IEEE 802.11 a/b/g/n access points.
The ES7528 provides a total of 28-ports:
•
24 Fast Ethernet PoE injector ports that can deliver 15.4 Watts (IEEE 802.3af) or 32 Watts (high power
PoE IEEE 802.3at)
•
4 Gigabit copper/SFP Combo uplink Ethernet ports
With network redundancy technology, the ES7528 can aggregate up to twelve Fast Ethernet and two Gigabit
rings while providing high-quality data transmission with less than 5ms network recovery time. To ensure
traffic switching without data loss and blocking, the ES7528 provides a 12.8G backplane with an integrated
non-blocking switching function. The ES7528 incorporates LLDP functionality and works with NetVision to
allow administrators to automatically discover devices and efficiently manage the industrial network
performance in large-scale surveillance networks. The ES7528 supports AC and dual 53VDC power inputs
that can be aggregated to provide redundancy. The ES7528 also provides alarm relay output signaling
functionality.
The ES7528 provides advanced Layer 2 management features including IGMP Query/Snooping, DHCP, 256
VLAN, QoS, LACP, LPLD, and the corrosion resistant robust design, the ES7528 is a revolutionary solution
for industrial surveillance applications.
