The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

This chapter describes IPS-4240 and IPS-4255 and how to install them. It also describes the accessories and how to install them. This chapter contains the following sections:
•Introducing IPS-4240 and IPS-4255
•Front and Back Panel Features
•Connecting IPS-4240 to a Cisco 7200 Series Router
•Installing IPS-4240 and IPS-4255
IPS-4240 and IPS-4255 deliver high port density in a small form factor. They use a compact flash device for storage rather than the hard-disk drives used in other sensor models.
IPS-4240 monitors up to 250 Mbps of aggregate network traffic on multiple sensing interfaces and is inline ready. It replaces IDS-4235. There are four 10/100/1000 copper sensing interfaces.
Note The 250-Mbps performance for IPS-4240 is based on the following conditions: 2500 new TCP connections per second, 2500 HTTP transactions per second, average packet size of 445 bytes, and the system running Cisco IPS 5.1 software. The 250-Mbps performance is traffic combined from all four sensing interfaces.
IPS-4255 monitors up to 600 Mbps of aggregate network traffic on multiple sensing interfaces and is also inline ready. It replaces IDS-4250-TX. There are four 10/100/1000 copper sensing interfaces.
Note IDS-4250-SX and the IDS-4250-XL are not being replaced by IPS-4255 at this time.
Note The 600-Mbps performance for IPS-4255 is based on the following conditions: 6000 new TCP connections per second, 6000 HTTP transactions per second, average packet size of 445 bytes, and the system running Cisco IPS 5.1 software. The 600-Mbps performance is traffic combined from all four sensing interfaces.
Note IPS-4240 and the IPS-4255 do not support redundant power supplies.
Note IPS-4240 is available with either AC or DC power.
This section describes the IPS-4240 and IPS-4255 front and back panel features and indicators.
Note Although the graphics show IPS-4240, the IPS-4255 has the same front and back panel features and indicators.

Table 6-3 lists the specifications for IPS-4240 and IPS-4255.
When an IPS-4240 is connected directly to a 7200 series router and both the IPS-4240 and the router interfaces are hard-coded to speed 100 with duplex Full, the connection does not work. If you set IPS-4240 to speed Auto and duplex Auto, it connects to the router but only at speed 100 and duplex Half.
To connect correctly at speed 100 and duplex Full, set the interfaces of both IPS-4240 and the router to speed Auto and duplex Auto. Also, if either interface is hard-coded, you must make the connection using a crossover cable.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 |
IPS-4240 and IPS-4255 accessories kit contains the following:
•DB25 connector
•DB9 connector
•Rack mounting kit—screws, washers, and metal bracket
•RJ45 console cable
•Two 6-ft Ethernet cables
To rack mount IPS-424 and IPS-4255, follow these steps:
Step 1 Attach the bracket to the appliance using the supplied screws.
You can attach the brackets to the holes near the front of the appliance.
Note The top hole on the left bracket is a banana jack you can use for ESD grounding purposes when you are servicing the system. You can use the two threaded holes to mount a grounding lug to ground the chassis.
Step 2 Use the supplied screws to attach the appliance to the equipment rack.
Step 3 To remove the appliance from the rack, remove the screws that attach the appliance to the rack, and then remove the appliance.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement 1030 |
To install IPS-4240 and IPS-4255 on the network, follow these steps:
Step 1 Position the appliance on the network.
Step 2 Attach the grounding lug to the side of the appliance.
Note Use 8-32 screws to connect a copper standard barrel grounding lug to the holes. The appliance requires a lug where the distance between the center of each hole is 0.56 inches. The ground lug must be NRTL listed or recognized. In addition, the copper conductor (wires) must be used and the copper conductor must comply with the NEC code for ampacity. A lug is not supplied with the appliance.
Step 3 Place the appliance in a rack, if you are rack mounting it.
For the procedure, see Rack Mounting.
Step 4 Attach the power cord to the appliance and plug it in to a power source (a UPS is recommended).
Step 5 Connect the cable as shown in Step 6 so that you have either a DB-9 or DB-25 connector on one end as required by the serial port for your computer, and the other end is the RJ-45 connector.
Note Use the console port to connect to a computer to enter configuration commands. Locate the serial cable from the accessory kit. The serial cable assembly consists of a 180/rollover cable with RJ-45 connectors (DB-9 connector adapter PN 74-0495-01 and DB-25 connector adapter PN 29-0810-01).
Note You can use a 180/rollover or straight-through patch cable to connect the appliance to a port on a terminal server with RJ-45 or hydra cable assembly connections. Connect the appropriate cable from the console port on the appliance to a port on the terminal server. For the instructions for setting up a terminal server, see Setting Up a Terminal Server.
Step 6 Connect the RJ-45 connector to the console port and connect the other end to the DB-9 or DB-25 connector on your computer.
Step 7 Attach the network cables.
IPS-4240 and IPS-4255 have the following interfaces:
•GigabitEthernet0/0, GigabitEthernet0/1, GigabitEthernet0/2, and GigabitEthernet0/3 (from right to left) are sensing ports.
•Management0/0 is the command and control port.
Step 8 Power on the appliance.
Step 9 Initialize the appliance.
For the procedure, see Initializing the Sensor.
Step 10 Upgrade the appliance with the most recent Cisco IPS software.
For the procedure, see Obtaining Cisco IPS Software.
You are now ready to configure intrusion prevention on the appliance.
If you have the IPS-4240 DC model, see Installing IPS-4240-DC.

The IPS-4240-DC-K9 (NEBS-compliant) model equipped with DC-input power supply must be terminated with the DC input wiring on a DC source capable of supplying at least 15 amps. A 15-amp circuit breaker is required at the 48 VDC facility power source. An easily accessible disconnect device should be incorporated into the facility wiring.
DC power guidelines are listed in Regulatory Compliance and Safety Information for the Cisco Intrusion Prevention System 4200 Series Appliance Sensor. For more information on working with electrical power and in an ESD environment, see Site and Safety Guidelines.
Note The DC return connection should remain isolated from the system frame and chassis (DC-I). This equipment is suitable for connection to intra-building wiring only.

A 15-amp circuit breaker is required at the 48-VDC facility power source. An easily accessible disconnect device should be incorporated into the facility wiring.
Step 5 Locate the DC-input terminal box.
Step 6 Power off IPS-4240-DC.
Make sure that power is removed from the DC circuit. To make sure all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position.
Step 7 Remove the DC power supply plastic shield.
Step 8 Strip the ends of the wires for insertion into the power connect lugs on IPS-4240-DC.
Step 9 Insert the ground wire into the connector for the earth ground and tighten the screw on the connector. Using the same method as for the ground wire, connect the negative wire and then the positive wire.
