600-Watt AC Power System

Product Overview

The 600-watt Redundant AC Power System (RPS), the PWR600-AC-RPS, is a separate chassis that provides redundant power for any combination of up to four of the following products:

• Cisco 4000 Series routers

• Cisco MC3810 Multiservice Access Concentrator

• Cisco 3600 Series access server/routers

• Cisco 2600 Series routers

• Cisco 2500 Series routers

• Cisco 2500 Series access servers

• Catalyst 2900 Series XL Ethernet switches

• Catalyst 1900 Series Ethernet switches

• Catalyst 2820 Series Ethernet switches

• FastHub 300 Series 100BaseT hubs

• FastHub 200 Series 100BaseT hub

• Fast Hub 100 Series 10/100BaseT hub

• HP 10Base-T Hub-16M

This power system is ideal for powering a stack or rack mounted set of any mix of these products in the NetBeyond extended network system of modular, stackable LAN and WAN products. It is flexible and cost-effective in addressing the uptime requirements of these offices by offering two levels of redundancy: quasi-redundant mode and fully redundant mode.

In quasi-redundant mode, the RPS can support four load units. In this configuration, the mean time between failure (MTBF) of the RPS substantially exceeds that of the power supply in the individual external devices (hubs, switches, routers and access servers). In fully redundant mode, the RPS can support two external devices with a special cable offering extremely high uptime. Individual external devices can be hot inserted without affecting other external devices in either configuration.

The RPS supports both local and remote monitoring of status. Front panel LEDs allow a quick local check of status for AC input power, DC output power, cooling fans, and system temperature. When one of the external devices that the RPS powers is a Cisco 3600 Series, the Cisco 3600 can receive and store status signals from the RPS. In turn, the RPS status stored on the Cisco 3600 series is available for remote monitoring via Simple Network Management Protocol (SNMP) products such as CiscoWorks.

Applications

The RPS is appropriate for applications that customers consider to be "mission critical." Whenever the customer`s business depends on reliable, fail-safe network access — the added reliability offered by the RPS is attractive.

Both the resiliency of the RPS to incur a failure and continue operating and its capability to remotely communicate current or impending failures are particularly valuable for remote locations.

Key Features and Benefits

The following are the features:

• Two redundant modes: quasi-redundant, and fully redundant

• Support of up to four of any combination of 150-watt external devices (hubs, switches, routers, and access servers)

• Hot insertion of external devices

• Dual AC inputs and power cords

• Two fully redundant AC input power modules

• Four DC output power modules

• Four one-to-one DC power cables (in model PWR600-AC-RPS-CAB)

• Front panel LEDs for AC input power, DC output power, fan, and temperature status

• Redundant cooling fans

• Remote monitoring using SNMP via a Cisco 3600 series

• 19-inch rack-mount kit included (24-inch optional)

The following are the benefits

• Increased network uptime

  • With dual AC input power modules power supply meantime between failures (MTBF) is significantly improved.

• Flexibility and cost effectiveness

  • A single RPS supports up to four external devices.

  • Matches the level of redundancy required to the specific application requirements.

• Advanced warning of possible failure

  • Front panel LEDs for AC input power, DC output power, and cooling status.

  • SNMP manageable via a Cisco 3600 Series router/access server

Introduction

Configuration Information

There are two versions of the RPS, one with four one-to-one DC power cables (PWR600-AC-RPS-CAB) and one without (PWR600-AC-RPS-NCAB). The RPS with four DC power cables is intended for powering up to four external devices (hubs, switches, routers, and access servers) in quasi-redundant mode. The RPS without DC power cables is intended for use in fully redundant mode where either one or two two-to-one DC power cables are ordered separately to support one or two external devices.

The following external devices incorporate RPS support into every chassis. In addition to having an internal AC supply every chassis includes a connector for being powered by the RPS.

• Catalyst 2900 Series XL Ethernet switches

• Catalyst 1900 Series Ethernet switches

• Catalyst 2820 Series Ethernet switches

• FastHub 300 Series 100BaseT hubs

• FastHub 200 Series 100BaseT hub

• Fast Hub 100 10/100BaseT hub

• HP 10Base-T Hub-16M

The following external devices must either be ordered from the factory with the capability to be powered by the RPS or an upgrade kit can be ordered to convert an AC or DC model in the field to an RPS model. When the product comes from the factory as an RPS model there is no internal AC or DC supply. When the product is converted in the field to be powered by the RPS, the AC or DC supply must be removed.

• Cisco 4000 Series routers

• Cisco MC3810 Multiservice Access Concentrator

• Cisco 3600 Series access server/routers

• Cisco 2600 Series routers

• Cisco 3600 Series access server/routers

• Cisco 4000 Series routers

The following products are not available from the factory with RPS support. They must be converted in the field to be powered by the RPS. When the product is converted in the field to be powered by the RPS, the AC or DC supply must be removed.

• Cisco 2500 Series routers

• Cisco 2500 Series access servers

The standard quasi-redundant DC power cable works with all external devices but the 2500 Series (four of the cables are included with PWR600-AC-RPS-CAB). The standard DC power cable is called a "22-to-18" cable because it has a 22-pin connector on the RPS end and an 18-pin connector on the external device end. The Cisco 2500 Series and the MC3810 Multiservice Access Concentrator requires a "22-to-8" DC power cable. This cable is not included with the Cisco 2500 field upgrade kit and must be ordered separately.

For supporting external devices in fully redundant mode, optional cables must be ordered separately. These cables are referred to as two-to-one cables because there are two connectors for the RPS end and one for the external device end. There is an 18 pin version of the two-to-one DC power cable and an 8 pin version (for the 2500 Series). The two-to-one cables are supported for the following external devices:

• Cisco 4000 Series routers

• Cisco 3600 Series access server/routers

• Cisco MC3810 Multiservice Access Concentrator

• Cisco 2600 Series routers

• Cisco 2500 Series routers

• Cisco 2500 Series access servers
