2.2 ERS 3000 Series
The Avaya Ethernet Routing Switch 3500 Series are high-performance, compact Ethernet switches
designed for small branch offices (typically 100 users or less). The ERS 3500 includes 10-port and 24-
port 10/100/1000BaseT models, and 24-port 10/100BASE-TX models.
The ERS 3510GT-PWR+, 3524GT-PWR+ and 3526T-PWR+ provide IEEE 802.3af-compliant (PoE,
15.4W) or 802.3at-compliant (PoE+, 32W) power on all ports, and are contained with an ORANGE line
surrounding the PoE ports.
ERS3500 PoE+ model switches support the following maximum power budget per switch:
- 3510GT-PWR+, 60Watts maximum in Low power budget mode (fanless operation), or 170W
maximum in High power budget mode (normal fan operation).
- 3524GT-PWR+ and 3526T-PWR+, 370Watts per switch maximum.
When you use ERS 35xx-PWR+ units, you can plug any powered device into a compliant front-panel port
and receive power in that port. ERS3500 series PoE switches do not yet support the Avaya Energy Saver
(AES) feature, but this is planned in a near future release.
The 24-port models will support stacking with the 5.1 release targeted for availability in February 2013.
Stack cables are sold separately to provide resilient stacking capability of up to 8 units in a stack with
software v5.1 running on the 24-port switches.
