Remove Components from the Chassis
To make the router light enough to install without a mechanical lift, you must remove most of
the components.
Perform the procedures described in the following sections to remove components from the
chassis:
 Remove the Power Supplies on page 101
 Remove the Routing Engine Housing on page 102
 Remove the Upper Impeller Assembly on page 102
 Remove the Fan Tray on page 103
 Remove the Cable Management System on page 104
 Remove the FPCs on page 105
 Remove the SCB on page 106
 Remove the Air Filter on page 107
 Remove the Lower Impeller Assembly on page 108
The procedures in this section apply only to initial
installation and assume that you have not yet connected
power to the router. If power is connected, completely
disconnect it before continuing. See “Disconnect AC Power
from the Router” on page 140 or “Disconnect DC Power
from the Router” on page 147.
If you are installing or replacing components in an
operational router, see the appropriate chapters in Part 3.
Do not stack components on top of one another after
removing them from the chassis. Place each one
individually on a flat, stable surface, either on an antistatic
mat or in an electrostatic bag.
Set the removed components far enough away from the
installation site that they will not be in the way as you lift
the chassis into the rack.
