Avaya 2550T-PWR Ethernet Routing Switch

A cost-effective 10/100BaseT Ethernet switching product perfectly suited for branch offices of larger enterprises, or the enterprise edge, requiring a low-cost but feature-rich solution in the wiring closet.

Convergence-ready, for VoIP and more

The Ethernet Routing Switch 2500 series offers outstanding value as a convergence-ready edge switch. It delivers 802.3af standards-based Power-over-Ethernet (PoE) to support IP Telephony and Wireless LAN access points.

ERS 2500 models are available with or without PoE. As not all network devices require PoE, the ERS 2500 provides the right mix of PoE and non-PoE ports, so you don’t have to pay for power capacity that you’re never likely to use. This also minimizes the concern for power and cooling requirements in the wiring closet that can sometimes be an issue with products that support PoE on all ports. This unique design results in a flexible and low-cost, convergence-ready solution that enables you to take advantage of:

  • Economically priced non-PoE ports for devices such as printers, servers and other devices that don’t require power from the network
  • The convergence capabilities of PoE to support IP phones, network cameras, wireless access points, security, lighting and access control devices (e.g., badge readers)

The ERS 2500 is an energy-efficient branch office or wiring closet edge solution that consumes 40 percent less energy than competing products. Resilient stacking provides a pay-as-you-grow solution that creates a single virtual switch for ease of configuration and management. Additionally, the ERS 2500 family also uses the IEEE standard 802.1AB for auto discovery of devices such as IP phones. Each 802.1AB-supporting device learns the identification, configuration and capabilities of neighboring devices, and provides these details to the network management system.

Avaya further extends the use of this protocol by coupling it with the ability to automatically configure a port with QoS settings and VLAN membership when a Avaya IP phone is detected. This provides fast and easy IP phone deployments across the network. Convergence is further supported through the ERS 2500’s Quality of Service (QoS) features. The Ethernet Routing Switch 2500 uses standards-based 802.1p and DSCP priority queuing to prioritize mission critical traffic such as VoIP.

Always on. Always available.

A stack of up to eight units can be created through the ERS 2500’s support of reliable stacking; via a stacking license or stack- enabled units. This allows the Ethernet Routing Switch 2500 series to scale up to 384 10/100 ports and 16 10/100/1000/ SFP combo ports in a single stack while maintaining its management simplicity. Furthermore, through sub-second failovers in case of switch or stacking cable failure, the Ethernet Routing Switch 2500 can offer customers a solution that allows them access to their applications and network resources any time.

Additionally, through the use of Cat5E Stacking Cables to interconnect the ERS 2500s, this intelligent solution enables its users to benefit from all of the resilience and scalability that comes from deploying a true stacking architecture yet maintains its cost-effectiveness and simplicity. To further complement the ERS 2500’s stacking architecture, Avaya also offers support for standards-based 802.3ad Link Aggregation as well as its own Multi-Link Trunking technology that allows users to create the grouping of ports to form high-speed trunks/aggregations. These bundles or groups of ports can be distributed across different units in the same stack, thus delivering higher levels of resilience in case of link or switch failure, can ensure that traffic arrives at its destination. Stack health check monitoring provides a real-time, at-a-glance view of stack operational status and health, further enhancing operational and management simplicity should any issues arise.

Securing access to the network

The ERS 2500 offers high levels of security and flexibility, allowing only authorized personnel to gain access to a company’s LAN. Whether it is through use of an IEEE 802.1X-based EAP client or through a user/ device MAC address, network managers can ensure that only those who have successfully been authenticated against a RADIUS server have access to their specified resources. For further flexibility, the ERS can support the authentication of multiple devices/users on a single port. For example, if a user’s PC connects into the network via an IP Phone (Figure 1), the PC and the IP Phone can be authenticated for authorized use to that port. Additionally, if your company frequently has visitors, support for a guest VLAN allows non-authenticated users to still use the network but to only have access to those resources that have been pre-specified for the guest VLAN such as Internet access.

Enterprise-class management

The ERS 2500 series is managed through an enterprise class Command Line Interface (CLI). The CLI provides a common industry look and feel to terminal commands, helping to reduce training and operational costs. Additionally, ERS 2500 series switches can be easily managed and configured using Device Manager or web-based management graphical user interfaces. Secure management of the switch occurs through features such as Secure Shell (SSHv2) for encrypted telnet management access using an SSH client, via Device Manager using Simple Network Management Protocol (SNMPv3) or using HTTPS/SSL secure web management. Additionally, an IP manager list can be used to specify which management stations can access the switch by specifying up to 10 authorized management station IP Addresses. Support for backing up and restoring an ASCII Configuration file provides the network administrator with the ability to quickly deploy the same configuration file among various switches as well as to maintain a backup of the switch configuration for future use –thus providing a solution that is simple to manage and maintain.
