Removing the Blower Modules
The blower module weighs 20.5 lb (9.3 kg). By removing the upper blower
module from the chassis, you reduce the top-end weight of the chassis by the
weight of the blower module. Unless you plan to strip all components to reduce
the overall weight of the chassis so you can shift the chassis by lifting it manually,
there is no advantage in removing the lower blower module. Remove the blower
modules as described in the “Removing the Blower Modules” section on
page 3-14.
Removing the Cards from the Chassis Card Cages
Unless you plan to strip all components to reduce the overall weight of the chassis
so you can shift the chassis by lifting it manually, there is no advantage in
removing the cards from the card cages. Reducing the overall weight of the
chassis is offset by the requirement to store the cards in an ESD-preventive and
dust proof (for fiber-optic cards) environment.
If you elect to remove the cards from the chassis card cages, remove the cards as
described in Chapter 3, “Installing the Router.”

Detaching the Supplemental Bonding and Grounding Connection
If your router has one or more bonding and grounding cables attached to any of
the bonding and grounding receptacles on the chassis, you must detach these cable
lugs from the chassis before you remove the chassis from the equipment rack.
Detach the bonding and grounding cable lugs from the chassis as instructed in the
“Detaching the Supplemental Bonding and Grounding Connection” section on
page 5-104.
