Hardware Configuration SpecsComponentQuantityRole & DetailsRoute Processor (RP)2 InstalledConfigured in a 1+1 redundant hardware operation mode. If the primary RP encounters a failure, the backup RP provides transparent failover.DC Power Supply (PSU)4 InstalledOperates utilizing 4x slots (Max). Standard -48VDC / -60VDC nominal inputs at 1600W each, offering fully redundant N+N or N+1 power zones.Fan Modules4 InstalledASR-9903-FAN tray units providing front-to-back airflow. Full system thermal management redundancy remains intact even during an individual fan module failure.Port & Expansion LayoutThe fixed faceplate contains 36 integrated physical slots that accommodate combinations of multi-rate speeds:

• 100GE Ports: 16 integrated QSFP28-based ports.
• 10GE Ports: 20 integrated SFP+-based ports.
• Flexibility Profiles: Ports can be natively broken out or grouped into configurations such as 16x100GE, 15x100GE + 10x10GE, or 14x100GE + 20x10GE.
• Pluggable Expansion: Features 1 slot for an optional Port Expansion Card (PEC) to add up to 2 Tbps of extra capacity (e.g., matching QSFP-DD 400G interfaces
