This chapter describes the equipment required to connect the Cisco RPS to external devices. The Cisco RPS includes two fully redundant AC input power modules and four DC output power modules for connection to external devices. The Cisco RPS supports a quasi-redundant configuration for all devices, fully redundant configuration for the referenced Cisco routers and concentrator, and redundant-with-reboot configurations for the referenced hubs and switches. However, the redundant-with-reboot configuration is not recommended because a power supply failure will cause an interruption while the hub or switch reboots. For an explanation of power source configurations, refer to "Overview."
 |
Caution The Cisco RPS AC input power modules are power-factor-corrected to comply with certain International Electrotechnical Commission (IEC) standards. Do not connect the Cisco RPS to an uninterruptible power supply (UPS) that has not been tested and designed for power-factor-corrected power systems. Do not connect the Cisco RPS to a ferro-resonant transformer. If you do either of these things, you could damage the Cisco RPS. |
This chapter contains the following sections:
You might need to order the following equipment:
The external devices have different configuration and cabling options outlined below and are discussed in detail under the referenced section of this manual:
Refer to the "Connecting Hubs" section for illustrations and procedures.
See the "Connecting Switches" section for illustrations and procedures.
Refer to the "Connecting Routers and the Cisco MC3810 Concentrator" section for illustrations and procedures.
The Cisco RPS ships in either of the following configurations:
Figure 3-1 and Figure 3-2 show the cables you can order, and Table 3-1 includes cable descriptions and lists the corresponding product order numbers. For ordering information, contact 800 553-6387, 408 526-7208, or cs-rep@cisco.com. See also the "Obtaining Documentation" section.
| Redundancy Configuration | For Use With | Cable Description | Cable Order Number |
|---|---|---|---|
Cisco 1516M hub (HP 10BASE-T Hub-16M), FastHub 400 series hubs, Catalyst 1900 series and Catalyst 2820 switches, Catalyst 2900 series and Catalyst 3500 series XL switches, Cisco 2600 series routers, Cisco 3620, Cisco 3640, and Cisco 3725 routers, and Cisco 4000 series routers |

Cisco 2500 series routers and access servers and Cisco MC3810 multiservice concentrators |
One-to-one cable, 22-pin to 8-pin, |

Cisco 2600 series routers, Cisco 3620, Cisco 3640, and Cisco 3725 routers, and Cisco 4000 series routers |
Two-to-one cable, 22-pin to 18-pin, |

Cisco 2500 series routers and access servers and Cisco MC3810 multiservice concentrators |
Two-to-one cable, 22-pin to 8-pin, |

FastHub 400 series hubs, Catalyst 1900 series and Catalyst 2820 switches, and Catalyst 2900 series and Catalyst 3500 series XL switches |
One-to-one cable, 22-pin to 18-pin, |
| 1The cables come in only one length. Custom cable-lengths are not available. Excessive voltage drop and marginal or failed operation can occur with cables of different lengths. Use of cables other than the ones listed can cause damage to the Cisco RPS or external device.
2This configuration is not recommended due to the 30-second reboot and downtime. |
External devices operated with the Cisco RPS must have a Cisco RPS connector. Cisco 2600 series routers, Cisco 3620, Cisco 3640, and Cisco 3725 routers, and Cisco 4000 series routers, and the Cisco MC3810 concentrator do not automatically ship with an RPS connector.
 |
Note The FastHub 400 series hubs, Cisco 1516M hub (HP 10ASE-T Hub-16M), Catalyst 1900 series and Catalyst 2820 switches, and Catalyst 2900 series and Catalyst 3500 series XL switches ship with an RPS connector and do not require a power adapter plate. |
If you did not order your router or concentrator with a Cisco RPS connector installed, you must order a power adapter plate that provides compatibility and must install the plate in place of your existing power supply.
If you need to order a power adapter plate for your router or concentrator, see Table 3-2, which lists adapter plates and corresponding product order numbers. Contact Cisco Customer Service at 800 553-6387, 408 526-7208, or cs-rep@cisco.com for ordering information. (See also the "Obtaining Documentation" section.)
Device-specific instructions for installing the RPS adapter plate are shipped with the plate and are also available on Cisco.com at http://www.cisco.com.
