Tests did not focus on the Cisco 2960 Series and HP ProCurve 2800/2900 Series since PoE was not supported on those devices at test time. Engineers also verified the PoE power management tool of Nortel-only products via CLI, Java Device Manager (JDM) and Web-based management. Without any external power supply attached to the tested devices, engineers measured the power consumption for a switch at factory default mode to determine how much the national average commercial electric cost over three years of continuous operation. Based on switch power consumption results, engineers calculated associated cooling costs from heat dissipation for all switches tested. Tests were conducted in October 2007.

Nortel Business Ethernet Switch BES50GE-24T PWR SMB Switch Evaluation vs Cisco Catalyst Express 500 and HP ProCurve Switch 2626-PWR

Document number: 208271
Release Date: 27 Feb 2008

Nortel commissioned The Tolly Group to evaluate its SMB-class Gigabit Ethernet LAN switch, the BES50GE, and compare it to similar entry-level “converged” offerings from Cisco Systems, Inc. and HP ProCurve.

The baseline requirement in selecting switches was that each provide highspeed data transfer with Gigabit Ethernet (GbE) and be able to power VoIP phones, security cameras and wireless Access Points (APs) via Power over Ethernet (PoE).

Neither Cisco nor HP offers a switch directly comparable to Nortel which uniquely combines GbE on all ports and PoE on half the ports. Both Cisco and HP offer SMB customers either PoE or GbE — but not both. With PoE a base requirement for convergence, the Fast Ethernet (FE) HP ProCurve 2626-PWR and Cisco Catalyst Express 500-24PC models were chosen. Tests were conducted in January 2008.

Nortel commissioned The Tolly Group to evaluate the company’s Ethernet Routing Switch (ERS) 4550T-PWR and 4548GT-PWR with Redundant Power Supply 15 (RPS 15), as well as the ERS 2526T-PWR and ERS 2550T-PWR to determine the price per port for delivering PoE, switch power consumption and heat dissipation.

Tolly Group engineers also measured the cost to deliver full PoE (~15.4W) on all ports simultaneously for the Nortel ERS switches tested versus Cisco Catalyst 3560G- 48PS, 3750G-48PS, 3560E-48PD, and 3750E-48PD; and HP ProCurve 2626-PWR and 2650-PWR switches. Tests did not focus on the Cisco 2960 Series and HP ProCurve 2800/2900 Series since PoE was not supported on those devices at test time. Engineers also verified the PoE power management tool of Nortel-only products via CLI, Java Device Manager (JDM) and Web-based management.

Without any external power supply attached to the tested devices, engineers measured the power consumption for a switch at factory default mode to determine how much the national average commercial electric cost over three years of continuous operation. Based on switch power consumption results, engineers calculated associated cooling costs from heat dissipation for all switches tested.

Tests were conducted in October 2007.
