Introducing IPS-4240 and IPS-4255
Note IPS-4240 and the IPS-4255 do not support redundant power supplies.
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 replaces IDS-4235. There are four 10/100/1000 copper sensing interfaces. IPS-4240 is
available with either AC or DC power. It monitors up to 250 Mbps of aggregate network traffic on
multiple sensing interfaces and is inline ready. The 250-Mbps performance for IPS-4240 is based on the
following conditions:
•2500 new TCP connections per second
•2500 HTTP transactions per second

Front and Back Panel Features
•Average packet size of 445 bytes
•Running Cisco IPS 5.1 or later
Note The 250-Mbps performance is traffic combined from all four sensing interfaces.
IPS-4255 replaces IDS-4250-TX. There are four 10/100/1000 copper sensing interfaces. It monitors up
to 600 Mbps of aggregate network traffic on multiple sensing interfaces and is also inline ready. 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
•Running Cisco IPS 5.1 or later
Note The 600-Mbps performance is traffic combined from all four sensing interfaces.

Connecting IPS-4240 to a Cisco 7200 Series Router
Connecting IPS-4240 to a Cisco 7200 Series Router
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.
Accessories
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

Installing IPS-4240 and IPS-4255
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.
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.

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 to the correct ports:
•GigabitEthernet0/0, GigabitEthernet0/1, GigabitEthernet0/2, and GigabitEthernet0/3 (from right to
left) are sensing ports.
•Management0/0 is the command and control port.
Caution Management and console ports are privileged administrative ports. Connecting them to an untrusted
network can create security concerns.
Step 8 Power on the appliance.
Step 9 Initialize the appliance.
Step 10 Upgrade the appliance with the most recent Cisco IPS software.
You are now ready to configure intrusion prevention on the appliance.

6.2
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.
Warning Before performing any of the following procedures, ensure that power is removed from the DC circuit.
To ensure that 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.
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.
Warning Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
