Chapter 4 Installing IDS-4235 and IDS-4250
Front-Panel Features and Indicators
IDS-4250 supports a 500-Mbps speed and can be used to protect gigabit subnets and traffic traversing
switches that are being used to aggregate traffic from numerous subnets. The sensing interface and the
command and control interface are both 10/100/1000BASE-TX. The optional interface is
1000BASE-SX (fiber). You can now install a second SX card in the IDS-4250. In addition, you can
upgrade IDS-4250 to full line-rate gigabit performance with the IDS Accelerator (XL) card. You can also
install the 4FE card to provide an additional four sensing interfaces. There is also an optional
10/100/1000TX adapter card that allows additional options for inline functionality beyond the 4FE card.
For the procedure for installing optional PCI cards, see
Installing Optional PCI Cards, page 4-12
.
Note
The 500-Mbps performance for IDS-4250 is based on the following conditions: 2700 new TCP
connections per second, 2700 HTTP transactions per second, average packet size of 595 bytes, system
running Cisco IPS 5.0 software.
Or you can order IDS-4250-XL with the XL card already installed. At 1 Gbps, IDS 4250-XL provides
customized hardware acceleration to protect fully saturated gigabit links as well as multiple partially
utilized gigabit subnets.
Note
The 1000-Mbps performance for IDS-4250-XL is based on the following conditions: 5000 new TCP
connections per second, 5000 HTTP transactions per second, average packet size of 595 bytes, system
running Cisco IPS 5.0 software.
