1 Required Tools and Equipment
To install an advanced integration module (AIM) in a Cisco modular router chassis, you need the following tools and equipment:
• Number 2 Phillips screwdriver or small flat-blade screwdriver
• 1/4-inch nut driver
• 3/16-inch open-end wrench
• Torx-15 screwdriver (for installation in Cisco 3660 only)
• ESD-preventive wrist strap
• Tape for DC circuit breaker handle
Safety Information
For safety information that you need to know before working on your Cisco router, refer to the Regulatory Compliance and
Safety Information document that accompanied your router and is accessible online on Cisco.com. For information about
accessing this document, see the “Where to Go Next” section on page 12 and the “Obtaining Documentation” section on
page 13.
Warning
Only trained and qualified personnel should be allowed to install or replace this equipment. To see translations of
the warnings that appear in this publication, refer to the Regulatory Compliance and Safety Information document
that accompanied this device.
Warning
Two people are required to lift the chassis. Grasp the chassis underneath the lower edge and lift with both hands.
To prevent injury, keep your back straight and lift with your legs, not your back. To prevent damage to the chassis
and components, never attempt to lift the chassis with the handles on the power supplies or on the interface
processors, or by the plastic panels on the front of the chassis. These handles were not designed to support the
weight of the chassis. To see translations of the warnings that appear in this publication, refer to the Regulatory
Compliance and Safety Information document that accompanied this device.
Caution Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry. Always follow ESD prevention
procedures when removing and replacing cards.
2 Opening the Chassis
To install or remove an AIM, you have to open the chassis. There are three different chassis types:
• Chassis of 1 rack unit (RU) height—has separable top and bottom halves (most Cisco 2600 series routers)
• Chassis of 2-RU height with removable cover—has flat cover with separating hinge (some Cisco 2600, Cisco 3600, and
Cisco 3700 series routers)
• Chassis with plug-in CPU/mainboard—all have 2 or more RU height (some Cisco 3600 and Cisco 3700 series routers)
Refer to the procedure that applies to your router. For more detailed instructions, refer to the online AIM installation procedure
on cisco.com.
The following warning applies to routers that use a DC power supply:
Warning
Before performing any of the following procedures, ensure that power is removed from the DC circuit. To ensure
that all power is OFF, locate the circuit breaker on the panel board that services the DC circuit, switch the circuit
breaker to the OFF position, and tape the switch handle of the circuit breaker in the OFF position. To see
translations of the warnings that appear in this publication, refer to the Regulatory Compliance and Safety
Information document that accompanied this device.
