Connection Methods and Cables

Table 2 summarizes the redundancy options and cable requirements for the various external devices that can be supported by the Cisco RPS.

Table 2	Redundancy Options and Cable Requirements
				Cable Order
Redundancy Configuration		DC-Powered Device	Cable Description	Number
Quasi-redundant		Cisco 1516M hub (HP 10BASE-T Hub-16M)	One-to-one cable,	CAB-RPS-2218=
(Routers, hubs, and		FastHub 400 series hubs	22-pin to 18-pin,
			4 ft. (1.22 m)1
switches)		Catalyst 1900 series, Catalyst 2820 series,
		Catalyst 2900 series and Catalyst 3500 series XL
		switches
		Cisco 2600 series and Cisco 4000 series routers
		Cisco 3620, Cisco 3640, and Cisco 3725 routers
		Cisco 2500 series routers and access servers	One-to-one cable,	CAB-RPS-2208=
		Cisco MC3810 multiservice concentrators	22-pin to 8-pin,
			4 ft. (1.22 m)1
Fully redundant		Cisco 2600 series and Cisco 4000 series routers	Two-to-one cable,	CAB-RPSY-2218=
(Routers only)		Cisco 3620, Cisco 3640, and Cisco 3725 routers	22-pin to 18-pin,
			4 ft. (1.22 m)1
		Cisco 2500 series routers and access servers	Two-to-one cable,	CAB-RPSY-2208=
		Cisco MC3810 multiservice concentrators	22-pin to 8-pin,
			4 ft. (1.22 m)1
Redundant with reboot2		FastHub 400 series hubs	One-to-one cable,	CAB-RPS-2218=
(Hubs and switches only)		Catalyst 1900 series, Catalyst 2820 series,	22-pin to 18-pin,
			4 ft. (1.22 m)1
		Catalyst 2900 series and Catalyst 3500 series XL
		switches

1.The 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.

2.This configuration is not recommended due to the 30-second reboot and downtime.

The connection options are shown in the following figures:

•Quasi-redundant—Figure 6. The AC input to the Cisco RPS is fully redundant, but the DC output to the external devices is not.

Note Quasi-redundant is the only recommended configuration for Cisco switches and hubs.
