Chapter 3 Installing the Cisco uBR10012 Router
Connecting the External AC-input Power Shelf to the Cisco uBR10012 Router
Connecting the Lineage Power Shelf to the UBR-PWR-DC-PLUS= Module
Prerequisites
•
Two Lineage AC-DC power shelves are required to supply power to the UBR-PWR-DC-PLUS=
modules to power on the Cisco uBR10012 router.
•
To meet Class A compliance standards, the ferrite beads must be installed on the DC “Y” power
cables exiting the Lineage power shelf within 6 inches from the DC terminal blocks. For more
details, see
Attaching Ferrite Beads on the Lineage Power Shelf, page 3-19
.
Required Tools and Equipment
•
3300 W DC PEM module (UBR-PWR-DC-PLUS=)
•
Two Lineage AC-DC power shelves
•
Two DC “Y” power cables (Amphenol), provided in Lineage accessory kit
•
Two alarm monitor cables, provided in Lineage accessory kit
•
Ferrite beads, provided in Lineage accessory kit
•
Flat-screw driver
•
10 mm hex socket driver
Note
We recommend that you use the DC “Y” power cables provided in the Lineage accessory kit. If you are
using a 4 AWG cable, use a high-flex high strand count power cable for optimal routing of the cables
under the front cover of the Cisco uBR10012 router. The 2 AWG wire is not supported on the
UBR-DC-PWR-PLUS= DC PEM module.
Steps
To connect the power shelf to the UBR-PWR-DC-PLUS= DC PEM module:
Caution
Do not have the AC power cables attached from the Lineage power shelves to the facility power sources,
while attempting to connect the DC power cables from the power shelves to the UBR-PWR-DC-PLUS=
modules of the Cisco uBR10012 router.
Step 1
Follow the steps to connect cables to the two Lineage power shelves, see
Figure 3-18
:
a.
Open the safety cover from above the DC terminal blocks by rotating the safety cover up and off of
the DC terminal blocks of the shelves
b.
Loosen and remove the M6 nuts.
c.
Attach the lugged ends of the DC “Y” power cables to left DC power terminal blocks of the two
power shelves. Secure the cables with the removed M6 nuts using a 10 mm hex socket driver with
an installation torque of 45-in lbs. (See
Figure 3-17
.)
d.
Close the safety cover on the DC terminal blocks.
e.
Attach the ferrite beads (Steward 28A5131-0A2) to the DC “Y” power cables pairs (both -48 V and
RTN cables) exiting the Lineage power shelves within 6 inches from the DC terminal blocks. See
“Attaching Ferrite Beads on the Lineage Power Shelf” section on page 3-19
.
