If You Already Have a Cisco AS5800

If You Already Have a Cisco AS5800

If you already have a Cisco AS5800, the Cisco AS5850 should be easy to adjust to. The following major differences should be noted:

The cooling module is 1 RU shorter.

The Dial Shelf Controller (DSC) and Cisco 7206 router shelf were replaced with a route switch controller (RSC) card, which goes in slots 6 and 7, not 12 and 13 (as with the DSC).

There is a new 2400-watt power shelf. This power module can use three 120V 15A connections or three 240V 10A connections, depending on what is available at your site.

Because the chassis is shorter, and a separate router shelf (or two) are no longer needed, three Cisco AS5850 gateways can fit in a standard rack, when DC-powered.

The separate power entry module (PEM) and power filter have been integrated into a single unit (PEMF).

Trunk cards can be used in any feature card slot.

All modems are universal ports and support voice, data, or fax connections. For details about universal ports, refer to the Cisco AS5850 Universal Gateway Card Guide, and the Cisco AS5850 Operations, Administration, Maintenance, and Provisioning Guide (available online at the following URL:

http://www.cisco.com/univercd/cc/td/doc/product/access/acs_serv/as5850/sw_conf/5850oamp/ index.htm.)

Command syntax has shifted slightly. Because you no longer need to distinguish the Cisco 5814 dial shelf from the Cisco 7206 router shelf, commands using the shelf/slot/port syntax are shortened to slot/port. The shelf abstraction is no longer needed.

System Components

The following sections in this chapter describe the core system components:

Field-Replaceable Units

For information about the feature cards used in the Cisco AS5850, refer to the Cisco AS5850 Universal Gateway Card Guide that shipped with your system. For information about other FRUs, review the rest of this chapter, or for detailed specification tables, refer to Appendix A, “Cisco AS5850 Specifications”, page 1-14

Route Switch Controller Card, page 1-14

DC-Input Power Entry Module, page 1-23

Power Requirements, page 1-28

The Cisco AS5850 is designed to be rack-mounted. A rack-mount kit is included with each

Cisco AS5850. Each rack-mount kit provides the hardware needed to mount the chassis in a standard, 19-inch equipment rack or standard telco rack. If you plan to use a 23-inch equipment rack, you must provide your own brackets or shelves to accommodate the Cisco AS5850 and optional AC power shelf. For clearance requirements and rack-mount installation considerations, refer to the section

Site Requirements” in Chapter 2, “Preparing for Installation.”
