Installing Interface Cards in IPS-4260
–
The speed and duplex settings are identical on the physical interfaces.
–
Both of the interfaces are administratively enabled.
•
Autonegotiation must be set on MDI/X switch ports connected to IPS-4260 and IPS 4270-20.
You must configure both the sensor ports and the switch ports for autonegotiation for hardware
bypass to work. The switch ports must support MDI/X, which automatically reverses the transmit
and receive lines if necessary to correct any cabling problems. The sensor is only guaranteed to
operate correctly with the switch if both of them are configured for identical speed and duplex,
which means that the sensor must be set for autonegotiation too.

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
