Installation and Replacement Suggestions
The following examples list recommended installation and replacement practices for the Cisco 6015
system modules.
Caution
Any module that is only partially connected to the backplane can disrupt system operation.
•
Do not force the module into its slot. This action can damage the pins on the backplane if they are
not aligned properly with the module.
•
Ensure that the module is straight and not at an angle when you install the module in the slot.
Installing the module at an angle can damage the module. Use the guide rails to install the
module correctly.
Hot Swapping Modules
The DSL interface module is a FRU; however, it is not hot swappable. Removing the DSL interface
module will interrupt the service for the entire system until it is replaced.
Caution
The DSL interface module must be installed and removed by a trained technician only.
Preventing Electrostatic Discharge Damage
Proper ESD protection is required whenever you handle Cisco equipment. ESD damage, which can occur
when electronic cards or components are improperly handled, results in complete or intermittent
failures. Use an antistatic strap when you handle any card or component.
Tip
Use the ESD grounding jack on the fan module for all maintenance except when you are removing the
fan module. Use the ESD grounding jack on the DC PEM when you are removing the fan module.
