Cisco ICS 7750 System Overview

This chapter tells how to operate the Cisco Integrated Communications System 7750 (Cisco ICS 7750). The chapter is organized as follows:

Hardware Summary

Chassis

The system is designed for use with Catalyst 3524-PWR XL switches (see "Switches" section).

Cards

The Cisco ICS 7750 can contain many combinations of cards. The ICS System Manager software detects the cards present at system startup.

Table 1-1 describes system cards. The number of cards installed in a chassis varies.

Table 1-1 Cisco ICS 7750 Cards

Card Name	Cards Per Chassis	Chassis Slot Number	Card Description	Number of External Ports Per Card
System processing engine 310 (SPE310)	1 to 5	1 through 6	A single-board computer that runs system software applications such as ICS System Manager and Cisco CallManager. The SPE310 on which ICS System Manager is installed will be referred to as the SPE310 running System Manager.	2 USB, 1 video, 1 keyboard.
Multiservice route processor 200 (MRP200)	0 to 5	1 through 6	A voice-and-data-capable router that can carry voice traffic over an IP network and that can link small-to-medium-size remote Ethernet LANs to central offices over WAN links. The MRP has two slots that support WAN interface cards (WICs), voice WAN interface cards (VWICs), and voice interface cards (VICs); two packet voice/data module (PVDM) slots for adding digital signal processors (DSPs); a dual in-line memory module (DIMM) slot for upgrading MRP memory; and a socket for a Virtual Private Network (VPN) module. The MRP200 does not have Flash memory.	Many types of ports are available, depending on which WICs, VICs, and VWICs are installed on each MRP.
MRP300	0 to 5	1 through 6	A voice-and-data-capable router that can carry voice traffic over an IP network and that can link small-to-medium-size remote Ethernet LANs to central offices over WAN links. The MRP has two slots that support WICs, VWICs, and VICs; two PVDM slots for adding DSPs; a DIMM slot for upgrading MRP memory; a slot for expanding Flash memory; and a socket for a VPN module. The MRP300 does have Flash memory.	Many types of ports are available, depending on which WICs, VICs, and VWICs are installed on each MRP.
Analog station interface 81 (ASI81)	0 to 5	1 through 6	A voice-and-data-capable router that can carry voice traffic over an IP network and can link small-to medium-size remote Ethernet LANs to central offices over WAN links (depending on the type of card installed in its WIC/VIC/VWIC slot) and can support connections to analog telephones, fax machines, and teleconferencing stations. Like MRPs, ASIs have two PVDM slots and a DIMM slot. The ASI81 does not have Flash memory.	Eight Foreign Exchange Station (FXS) ports. One slot for a WIC, VIC, or VWIC.
MRP3-8FXS	0 to 5	1 through 6	A voice-and-data-capable router that can carry voice traffic over an IP network and can link small- to medium-size remote Ethernet LANs to central offices over WAN links (depending on the type of card installed in its WIC/VIC/VWIC slot) and can support connections to analog telephones, fax machines, and teleconferencing stations. Has two PVDM slots, a DIMM slot, and a slot for expanding Flash memory. This card has Flash memory.	Eight FXS ports One slot for a WIC, VIC, or VWIC.
ASI160	0 to 5	1 through 6	An analog gateway that supports connections to telephones, fax machines, and teleconferencing stations. Like MRPs, ASIs have two PVDM slots and a DIMM slot. The ASI160 does not have Flash memory.	16 FXS ports.
MRP3-16FXS	0 to 5	1 through 6	An analog gateway that supports connections to telephones, fax machines, and teleconferencing stations. Has two PVDM slots, a DIMM slot, and a slot for expanding Flash memory. This card has Flash memory.	16 FXS ports.
System Switch Processor (SSP)	1	7	An Ethernet switch that passes data among all system cards and to any other switches connected to the system.	2 Ethernet 10/100.
System alarm processor (SAP)	1	8	A module that monitors the chassis, power supply modules, fans, and their environment, feeding real-time data to the SPEs. You can use the SAP console port to communicate with other system cards through a modem or terminal connection.	3 serial (2 COM, 1 console.)

Supported WICs, VICs, and VWICs

MRP200 and MRP300 cards, which have two slots, and ASI 81 and MRP3-8FXS cards, which have one slot, accept existing VICs, WICs, and VWICs used in Cisco 1700, 2600, and 3600 series routers. This interface card support helps you build upon existing Cisco networks while maintaining interoperability and consistent end-to-end service between locations.

Power Supply Modules

Slots for two 200W power supply modules are located on the right side of the system chassis. If your system has two power supply modules, normal operation can continue even if only one power supply module is functioning.

Backup Power

If you intend to use a backup power device such as an uninterruptible power supply (UPS), avoid devices that use ferroresonant technology. A UPS that uses ferroresonant technology can become unstable when used with components that can cause substantial current draw fluctuations, such as Catalyst 3524-PWR XL switches. Cisco recommends that you use the Cisco redundant power supply (RPS) 300 to provide backup power to Catalyst 3524-PWR XL switches.

Fans

The system is cooled by four fans, which are located in the fan tray at the bottom of the system chassis. Individual fans are not field replaceable—you should replace the entire fan tray if there is a problem with one or more system fans.

Switches

You can attach a stack of interconnected Catalyst 3524-PWR XL switches to a Cisco ICS 7750. Refer to the documentation that came with your switches for additional information.
