Preparing the Defective Chassis
To prepare the defective chassis for component removal you must disconnect the
power from the PDU and disconnect the RP cables, line card network interface
cables, and alarm card cables. These procedures are described in the following
sections:
• Disconnecting Power from the Power Distribution Unit, page 6-70
• Disconnecting RP Cables, page 6-70
• Disconnecting Line Card Interface Cables, page 6-71
• Disconnecting Alarm Card Cables, page 6-71

Disconnecting Power from the Power Distribution Unit

Before moving the components from the defective chassis to the replacement
chassis, you must first power down the router. Although many of the components
in this procedure support OIR, that is, they are hot-swappable, the router must be
powered down and completely disconnected from the power sources before you
remove the PDU.
Warning
Power down your router.
To power down the router, see the “Powering Down the Router” section on
page 6-2.

Disconnecting RP Cables

Identify and write down each of the RP cable connections on a piece of paper
before you disconnect the cables. You must disconnect any cables that are
connected to the RP console port, auxiliary port, or to either of the Ethernet ports,
RJ-45 or MII (GRP only). After disconnecting the cables, either leave them in the
cable management bracket for reuse with the new RP, or move them away from
the chassis and place them safely aside.
