AIM Installation and Removal
AIM Installation and Removal
Overview
Advanced integration modules (AIMs) provide hardware-based support for additional features. AIMs
plug into a connector on the motherboard and require no external interfaces or connections. Each AIM
sold as a spare is supplied with a label that identifies its type.
Cisco 3800 series routers have two AIM connectors, labeled AIM0 and AIM1. See Figure 51 and
Figure 52 for AIM connector locations. Table 7 lists the AIMs supported on Cisco 3800 series routers.
Accessory Kits
The mounting hardware required to install an AIM in a Cisco 3800 series router consists of two
machine-thread metal standoffs, two machine-thread metal screws, and one plastic standoff with a snap
fit on both ends.
Some AIMs are shipped with different accessory kits or more than one accessory kit. If necessary, use
the plastic standoff with a snap fit on both ends from one kit and the machine-thread metal standoffs and
machine-thread metal screws from a different kit.
Installing an AIM
The following procedure requires a 1/4-inch nut driver and a number 1 Phillips screwdriver.
Caution When you remove or install an AIM, always wear an ESD-preventive wrist strap, and ensure that it
makes good contact with your skin. Connect the equipment end of the wrist strap to the metal part of the
router.
Caution Handle AIMs by the edges only. AIMs are ESD-sensitive components and can be damaged
by mishandling.
