Cisco ICS 7750 Product Overview

Cisco ICS 7750 Product Overview

This chapter briefly describes the Cisco Integrated Communications System (ICS) 7750 hardware and includes the following sections:

Introduction

The Cisco ICS 7750 integrates the functionality of the following voice and data network components:

A typical system configuration is shown in Figure 1-1.

A Cisco ICS 7750 network includes peripheral hardware components such as the following:

Key Features

The Cisco ICS 7750 can be installed in a standard 19-inch rack or on a desktop. The chassis supports the standard 6U Eurocard form factor. The chassis backplane has six double-wide interchangeable slots and two single-wide fixed slots. The eight slots are accessed through the front panel and are color-coded and keyed to assist in slot-sensitive card placement. All cards can be hot swapped.

Note   Hot swapping some cards can affect system performance. For more information, see "Removing and Installing Subsystem Components" in Chapter 3, "Installation."

The Cisco ICS 7750 supports up to two hot-swappable, 240W power supply modules. The power supply module slots are accessible from the front of the chassis.

The hot-swappable, front-accessible fan tray holds four fans, designed to cool the power supply modules and system boards with a front-to-back air flow. The cooling fans are monitored for temperature and speed control through the system alarm processor card.

Chassis Features

The chassis has the features shown in Figure 1-2 and Figure 1-3:

Processor Cards Overview

Table 1-1 briefly describes each of the cards that can be installed in the Cisco ICS 7750 chassis. For a detailed description of the cards, including LED and port descriptions, see "Cisco ICS 7750 Processor Cards."

Card Number per System Card Description Port Description

System processing engine

1-5

A single-board computer that runs system software applications such as Cisco ICS 7700 System Manager and Cisco CallManager.

No front-panel ports.

Multiservice route processor

up to 5

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. The multiservice route processor has two slots that support combinations of WAN interface cards (WICs), voice WAN interface cards (VWICs), and voice interface cards (VICs).

Note   See Table 2-5 in Chapter 2, "Preparing for Installation" for the WIC, VWIC, and VIC combinations supported on this card.

Supports the data and voice interface port types listed in Table 1-2.

System alarm processor

1

A module that monitors the status of the chassis, power supply modules, and fans, feeding real-time data to the system processing engines. You can use the system alarm processor console port to communicate with other system cards through a modem or terminal connection.

System switch processor

1

An Ethernet switch that passes data between all system cards and to any other Ethernet switches connected to the system.

Two Ethernet 10/100 ports

Table 1-2 lists the WICs and VICs that can be installed in the multiservice route processor card.

Power Supply Overview

This section briefly describes the power supplies that are used with the Cisco ICS 7750. For a detailed description of the power supplies and how to use them with the chassis, see "Cisco ICS 7750 Power Information."

Internal Power Supply Modules

As shown in Figure 1-2, there are slots for two 240W power supply modules on the right side of the system chassis. If your system has two power supply modules, it has redundant power—normal operation can continue, even if only one of the two power supply modules is delivering power to the system.

External Uninterruptible Power Supply

The uninterruptible power supply (UPS) is an optional component that provides the following support for the Cisco ICS 7750 and Catalyst switches:

  If utility power does not return to normal operation, the UPS continues to supply power from its internal batteries to the Cisco ICS 7750.

For detailed information on the UPS, refer to the User's Manual APC Smart-UPS that came with the UPS.

External Redundant Power Supply

The redundant power supply (RPS) is an optional component that provides redundant power to the Catalyst switches that are connected to the Cisco ICS 7750. Each Cisco RPS 300 can support up to six Catalyst switches.

For more information on power supply configurations for the Cisco ICS 7750 that include the Cisco RPS 300, see "Cisco ICS 7750 Power Information."
