Chapter 6 Installing IPS-4260
Supported PCI Cards
IPS-4260 has two built-in Gigabit Ethernet network ports and six expansion slots. The network port
numbers increase from right to left and the expansion slot numbers increase from bottom to top and from
right to left as shown in
Figure 6-4 on page 6-6
. Slots 2 and 3 are PCI-Express connectors and the other
expansion slots are PCI-X slots. Slots 1 through 3 are full-height slots and slots 4 though 6 are
half-height slots. The built-in management port is called Management0/0 and the built-in sensing
interface is Gigabit-Ethernet0/1. For more information on sensor interfaces, see
Sensor Interfaces,
page 1-3
.
Note
Only expansion slots 2 and 3 are supported at this time.
For improved reliability, IPS-4260 uses a flash device for storage rather than a hard-disk drive. IPS-4260
supports two optional network interface cards, the 2SX Fiber card, and the 4GE bypass interface card
that contains the hardware-bypass feature. Initially IPS-4260 supports only the built-in interfaces and
these two interface cards. For more information on the 4GE bypass interface card, see
Hardware Bypass,
page 6-3
.
IPS-4260 monitors greater than 1 Gbps of aggregate network traffic on multiple sensing interfaces and
is also inline ready. It replaces IDS-4250-XL. It supports both copper and fiber interfaces.
Note
The 1-Gbps performance for IPS-4260 is based on the following conditions: 10,000 new TCP
connections per second, 100,000 HTTP transactions per second, average packet size of 450 bytes, and
the system running Cisco IPS 5.1 software. The 1-Gbps performance is traffic combined from all sensing
interfaces.
IPS-4260 ships with one power supply, but it supports redundant power supplies. For more information,
see
Installing and Removing the Power Supply, page 6-21
.
Note
IPS-4260 operates in load-sharing mode when the optional redundant power supply is installed.
Supported PCI Cards
IPS-4260 supports the following PCI cards:
•
4GE bypass interface card (part number IPS-4GE-BP-INT=)
Provides four 10/100/1000BASE-T (4GE) monitoring interfaces (allowing up to 9 total monitoring
interfaces). The 4GE bypass interface card support hardware bypass.
