Installing and Removing NIMs and SMs
Network Interface Modules (NIMs), Service Modules (SMs) and the Cisco E-Series Server Modules
plug into the various slots on the motherboard. SMs are sold as a spare part, and they have a label that
identifies the SM type. See the following sections for SM installation tasks:
Note The procedures in this section apply to NIMs, SMs, and the Cisco E-Series Server modules.
• Software Requirement for SMs, page 6-24
• Locating an SM or NIM, page 6-24
• Removing an SM or NIM, page 6-24
• Installing an SM, page 6-24
• Verifying SM Installation, page 6-25
Caution Always wear an ESD-preventive wrist strap and ensure that it makes good contact with your skin when
you remove or install an SM. Connect the equipment end of the wrist strap to the metal part of the
chassis.
Caution Handle SMs and NIMs by the edges only. SMs are ESD-sensitive components and can be damaged by
mishandling.
