Removing Components from the Chassis to Reduce Weight

Removing Power Modules
OL-17440-01
If your router is equipped with the DC-input power shelf, disconnect the eight
source DC positive and negative power cables and the single ground cable from
the terminal studs on the back panel of the power shelf as instructed in the
"Removing and Installing a DC-Input Power Shelf" section on page
A fully-equipped router can weigh as much as 415 lb (188 kg). To reduce the
top-end weight of the chassis and lower the center of gravity, which might make
the chassis more stable as you move it, you may choose to remove some of the
components from the chassis.
Procedures in the following sections describe the steps for removing some of the
router components:

Each AC-input power supply weighs 12.7 lb (5.7 kg). By electing to remove the
three power supplies from the standard AC-input power shelf, you reduce the
top-end weight of the chassis by approximately 38.1 lb (17.1 kg). By electing to
remove the four power supplies from the optional AC-input power shelf, you
reduce the top-end weight of the chassis by approximately 50.8 lb (22.8kg)
Remove the AC-input power supplies as described in the
Power Supplies" section on page
Each DC-input power entry module weighs 6.4 lb (2.9 kg). By electing to remove
the four power entry modules from the power shelf, you reduce the top-end weight
of the chassis by approximately 25.6 lb (11.6 kg). Remove the DC-input power
entry modules as described in
page 3-12.
