Asynchronous Transfer Mode Interface Processor (AIP) Installation and Configuration 23
ATM Interface Cables
Step 5
Place the back of the interface processor in the slot and align the notch on the bottom of
the carrier with the groove in the slot. (See Figure 8a.)
Step 6
While keeping the interface processor parallel to the backplane, carefully slide the
interface processor into the slot until the back of the faceplate makes contact with the
ejector levers, then stop. (See Figure 8b.)
Caution
Always use the ejector levers when installing or removing processor modules. A module
that is partially seated in the backplane will cause the system to hang and subsequently crash.
Step 7
Using the thumb and forefinger of each hand to pinch each ejector lever, simultaneously
push the top ejector lever down and the bottom ejector lever up until both are parallel to
the faceplate. (See Figure 8c.)
Step 8
Tighten the captive screws on the top and bottom of the interface processor faceplate to
prevent the interface processor from becoming partially dislodged from the backplane
and ensure proper EMI shielding. (These screws must be tightened to meet EMI
specifications.)
Caution
To ensure adequate space for additional interface processors, always tighten the captive
installation screws on each newly installed interface processor before you insert any additional
interface processors. These screws also prevent accidental removal, and provide proper grounding
and EMI shielding for the system.
ATM Interface Cables
An ATM interface cable is used to connect your router to an ATM network or to connect two routers
back-to-back.
The AIP can support interfaces that connect to the following physical layers:
•
Transparent Asynchronous Transmitter/Receiver Interface (TAXI) 4B/5B 100-Mbps multimode
fiber-optic
•
SONET/SDH 155-Mbps multimode fiber-optic—STS-3C or STM-1
•
SONET/SDH 155-Mbps single-mode fiber-optic—STS-3C or STM-1
•
E3 34-Mbps coaxial cable
•
DS3 44.736-Mbps ( 20 parts per million [ppm]) coaxial cable
