Chapter 3 Installing the IPS 4270-20

Product Overview

Warning

This product relies on the building’s installation for short-circuit (overcurrent) protection. Ensure that

the protective device is rated not greater than 120 VAC, 20 A U.S. (240 VAC, 16-20 A International).

Statement 1005

Warning

This equipment must be grounded. Never defeat the ground conductor or operate the equipment in the

absence of a suitably installed ground conductor. Contact the appropriate electrical inspection

authority or an electrician if you are uncertain that suitable grounding is available.

Statement 1024

Warning

Blank faceplates and cover panels serve three important functions: they prevent exposure to

hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI)

that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not

operate the system unless all cards, faceplates, front covers, and rear covers are in place.

Statement

1029

Warning

This unit might have more than one power supply connection. All connections must be removed to

de-energize the unit.

Statement 1028

Note Removing the appliance chassis cover does not affect your Cisco warranty. Upgrading the IPS 4270-20

does not require any special tools and does not create any radio frequency leaks.

Note In IPS 7.1, rx/tx flow control is disabled on the IPS 4270-20. This is a change from IPS 7.0 where rx/tx

flow control is enabled by default.

Caution Do not operate the IPS 4270-20 for long periods with the chassis cover open or removed. Operating it in

this manner results in improper airflow and improper cooling that can lead to thermal damage.

Note On IPS sensors with multiple processors (for example, the IPS 4260 and IPS 4270-20), packets may be

captured out of order in the IP logs and by the packet command. Because the packets are not processed

using a single processor, the packets can become out of sync when received from multiple processors.

Product Overview

The IPS 4270-20 delivers up to 4 Gbps of performance in media-rich environments and 2 Gbps in

transactional environments enabling you to protect fully saturated Gigabit networks and aggregate

network traffic on multiple sensing interfaces. The IPS 4270-20 is also inline ready and has support for

both copper and fiber NICs thus providing flexibility of deployment in any environment.
