Cisco WS-P4603-2PSU Power over Ethernet Power Shelf for Catalyst 4006 - Used Pull
Used with Cisco Catalyst 4006 Switches with Power over Ethernet
In order to provide in-line power using the Catalyst 4006 switch, you must add on several other components. In-line power is only available on the Cisco Catalyst 4006 and not the Cisco Catalyst 4003 because only the Cisco Catalyst 4006 chassis has the ability to accept the Power Entry Module (PEM) and also has traces on the back-plane which allow the DC power to be supplied to inline-power capable line cards. To enable in-line power on the Cisco Catalyst 4006, you must have the Cisco Catalyst 4000 Auxiliary DC Power Shelf and at least two power supplies (WS-P4603-2PSU). The power shelf can accept up to three power supplies (WS-X4608) for N+1 redundancy. At least two are required for in-line power to work. Special cables (which are included with the power supplies) are used to attach each power supply to the PEM (WS-X4095-PEM). Finally, you must have an in-line power capable line card in the chassis. The WS-X4148-RJ45V is a 48 port in-line power capable 10/100 Ethernet switching module. The picture below does not show the in-line power daughter card that is included with the Cisco Catalyst 4148. It is similar to the daughter-card on the Cisco Catalyst 6000 module. The Cisco Catalyst 4006 switch operates identically to the Cisco Catalyst 6000 switch, in respect to in-line power detection and delivery.
