Introduction

Cisco Content Engine 500 series units are Internet content delivery devices that offer content caching, hosting, and other content-based services. The Content Engine sits on the WAN edge between your small business site, enterprise, or service provider network and the Internet.

The Content Engine 500 series offers the following Content Engine models for high-, medium-, and low-end applications:

Model	Product Number
Content Engine 590	CE-590 CE-590-DC CE-590-CDN CE-590-DC-CDN
Content Engine 560	CE-560 CE-560-CDN
Content Engine 507	CE-507 CE-507-CDN
Content Engine 507-AV	CE-507AV-CDN

Content Engine 590

The Content Engine 590 (CE-590) is a high-end Content Engine that services Internet service providers and large enterprise networks. The Content Engine sits on the WAN edge between your large enterprise or service provider network and the Internet and is designed to handle DS-3 traffic at 45 Mbps speed.

The CE-590 is configured for AC-input power, whereas the CE-590-DC is configured for DC-input power. The default factory configuration comes with one power supply installed.

Note   For purposes of simplicity, all models of the Content Engine 590 are hereafter referred to jointly as the CE-590.

The CE-590 has two internal 18-gigabyte (GB) Ultra2 LVD SCSI hard drives and an external SCSI port for attaching a six-drive Cisco Storage Array that increases the Content Engine storage capacity by an additional 108 GB (6 x 18 GB).

Table 1-1 lists the storage and memory specifications for the CE-590.

Functional Description

Depending on the model you purchased, your Content Engine operates as either a component of a Content Delivery Network or as a content caching device.

Content Delivery Network Component

Cisco Content Engines installed with Cisco CDN software are the content delivery components of a larger, Cisco Content Delivery Network (CDN) solution, which includes content routing, content switching, content distribution and management, and content services, as well as content delivery. Content Engines installed with Cisco CDN software are deployed in conjunction with Content Routers and Content Distribution Managers to create a complete Content Delivery Network system.

The CDN solution offers accelerated content delivery, hosting, and other content-based services. The CDN solution addresses the need to distribute and receive high-bandwidth, media-rich content across the Internet or an intranet without performance losses or content delivery delays.

Content Caching Device

Cisco Content Engines installed with Cisco Cache software accelerate content delivery and optimize bandwidth usage by transparently caching frequently accessed content and fulfilling content requests locally rather than traversing the Internet or intranet to a distant server farm each time a request is made. The Content Engine works in tandem with a router to handle Web traffic, including user requests to view pages and graphics (objects) on World Wide Web servers—whether internal or external to your network.

To implement Cisco Content Engines installed with Cisco Cache software within your existing network, your network must support Cisco IOS software and Web Cache Coordination Protocol (WCCP). The WCCP redirects Hypertext Transfer Protocol (HTTP) traffic to a Content Engine, and the Content Engine replies to those requests.

System Hardware Features

Figure 1-1 shows the Content Engine front panel, Figure 1-2 shows the Content Engine rear panel with one AC power supply, and Figure 1-3 shows the Content Engine rear panel with one DC power supply.

Ports, Receptacles, and LEDs

Table 1-5 describes the front and back panel ports and receptacles. (See the front panel in Figure 1-1 and the back panel in Figure 1-2 and Figure 1-3.)

Warning To avoid electric shock, do not connect safety extra-low voltage (SELV) circuits to telephone-network voltage (TNV) circuits. LAN ports contain SELV circuits, and WAN ports contain TNV circuits. Some LAN and WAN ports both use RJ-45 connectors. Use caution when connecting cables.

System	Green	On	The network connection is active (packets are being sent or received).
LINK	Green	On	The Content Engine is connected to the network.
100 Mbps	Green	On	The connection is a 100BASE-TX (Fast Ethernet) connection.
Slot 0	Green	On	Slot 0 is active.

		Rolling	Reboot has begun. In a rolling display, the four LEDs give the appearance of a light that repeatedly moves from left to right.

Cables and Connectors

This section describes the cables and connectors that connect your
Content Engine to a terminal and to the external network.

Console Cable

The Content Engine comes with a console cable kit that includes the following cable and adapters:

• One RJ-45 to RJ-45 rollover cable

• Two RJ-45 to DB-9 adapters

Use the rollover cable to connect the Content Engine console port to the COM port of an ASCII terminal or a PC running terminal emulation software.

The console port on the Content Engine is configured as data terminal equipment (DTE) and uses an RJ-45 connector. A console cable kit is provided with your Content Engine to connect a console (an ASCII terminal or PC running terminal emulation software) to the console port. The console cable kit contains an RJ-45 to RJ-45 rollover cable and two RJ-45 to DB-9 female DTE adapters.

By attaching an RJ-45 to DB-9 adapter to the rollover cable, you create an RJ-45 to DB-9 null modem cable.

You can identify a rollover cable by comparing the two modular ends of the cable, as shown in Figure 1-4. Holding the cable ends in your hands, side by side, with the tab at the back, the wire connected to the pin on the outside of the left connector (pin 1) should be the same color as the pin on the outside of the right connector (pin 8).

Network Cables

An Ethernet cable is required to connect the Content Engine to your network. To connect the Content Engine to your network, you must use one of the following types of cables:

• Unshielded twisted-pair (UTP) straight-through cable with RJ-45 connectors to connect the Content Engine to a Medium Dependent Interface-crossover (MDI-X) port

• RJ-45 to RJ-45 crossover cable to connect the Content Engine to another
  MDI port

---

Note   The Ethernet ports on the Content Engine are MDI.

---

Use a Category 5 UTP cable to connect to a 100BASE-T network.

Ethernet Cable Pinouts

Table 1-7 shows the pinout for a straight-through 100BASE-T cable.

Table 1-8 shows the pinout for a crossover 100BASE-T cable.
