600-Watt Redundant AC Power System
Overview
Today, for a growing number of small and medium businesses,
networks are at the heart of their ability to communicate with and
be responsive to their customers, suppliers, and employees. This
scenario is driving the demand for networks to be available 24
hours a day, 7 days a week. While software and hardware
redundancy have long been a requirement for the core networks
of large companies, increasingly both their smaller offices and
offices of small and medium-sized businesses have the same
needs.
On products for small and medium-sized offices,
Cisco Systems has long met the requirement for software
redundancy with Cisco IOS
®
features such as Hot Standby
Routing Protocol (HSRP). To meet the need in these offices for
power redundancy, Cisco is adding redundant power as an option
across a range of Cisco routers, switches, hubs, and access
servers.
600-Watt Redundant AC Power System
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 1516M hub (HP 10Base-T Hub-16M)
• FastHub
®
400 Series 10/100 hubs
• Catalyst
®
1900 Series Ethernet switches
• Catalyst 2820 Series Ethernet switches
• Catalyst 2900 Series XL switches
• Catalyst 3500 Series XL switches
• Cisco 2500 Series routers
• Cisco 2500 Series access servers
• Cisco 2600 Series routers
• Cisco 3620/3640 Series routers
• Cisco 3725 Series routers
• Cisco MC3810 Multiservice access concentrator
• Cisco 4000 Series routers
This power system is ideal for powering these stackable LAN and
WAN products. It is flexible and cost-effective in addressing the
uptime requirements of these offices by offering three levels of
redundancy:
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). The RPS has demonstrated MTBF in excess of
500,000 hours. 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. In
“redundant with reboot” mode, the RPS supports 4 switches or
hubs. In this mode, AC power is connected directly to the hub or
switch in addition to the power from the RPS. The RPS works in
standby mode, so if the power supply in the hub or switch fails,
the hub or switch will reboot and come up again powered by the
RPS. (This configuration is not generally recommended due to the
30-second reboot and down time.)
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 or 2600 Series, the Cisco 3600 or 2600 can
receive and store status signals from the RPS. In turn, the RPS
status stored on the Cisco 3600 or 2600 series is available for
remote monitoring via Simple Network Management Protocol
(SNMP) products such as CiscoWorks.
