Features
Cisco XR 12406 Router has the following key features:
• Route Processor (PRP-2)—Slot 5 (bottom slot) is the recommended slot for
the first route processor. When the router is equipped with a redundant route
processor, it can be installed in any of the five regular line card slots.
• Line Cards—Up to five OC-192 line cards, four if redundant route processors
are installed. These slots support the online insertion and removal (OIR)
feature so installed cards are hot-swappable: A failed card can be removed
and replaced with the router powered on.
• Clock and Scheduler Cards (CSCs) and Switch Fabric Cards (SFCs)—Two
dedicated hot-swappable slots for CSCs; three dedicated hot-swappable slots
for SFCs.
Note When operating your router with a single CSC, the second CSC slot must
have a CSC blank filler (MAS-GSR6-CSCBLNK=) installed to ensure
EMI compliance.
• Two dedicated alarm card slots (for 1+1 redundancy)
• Alarm and Illumination—Alarm and illumination for operating ranges in the
card cage, clock and scheduler card, and switch fabric card bays.
• Two hot-swappable AC-input power supplies or DC-input power entry
modules (PEMs).
Note When operating your router on a single AC-input power supply or
DC-input PEM, the second power module bay must have a blank filler
(MAS-GSR-PWRBLANK=) installed to ensure EMI compliance.
• All power modules and other field replaceable units (FRUs), except for the
air blower module and the power distribution unit (PDU), can be removed
from the front of the chassis.
• All source power connections are located at the rear of the chassis on the PDU
(see
Figure 1-3 ).
• A new stylish front door hides router cabling and can be installed to open
from the right side or left side to give you total flexibility.
