Q
What modules and interface cards are available for Cisco 8000 Series Routers?
A
Cisco 8000 Series offers high-density 400Gb line cards, 100Gb/200Gb interface modules, multicore service modules, optical interface cards, and dedicated power modules compatible with all Cisco 8000 platforms.
Q
How do I install a module in a Cisco 8000 Series router?
A
To install a module, power down the router, insert the module into an empty slot until it clicks, secure the captive screws, then power up and confirm detection via the CLI show platform command.
Q
Are Cisco 8000 Series modules hot-swappable?
A
Most Cisco 8000 line cards and optical interface modules support hot-swap under Cisco IOS XR, while service and power modules require a graceful shutdown for safe replacement.
Q
What throughput options do Cisco 8000 line cards offer?
A
Cisco 8000 Series line cards deliver 100Gb, 200Gb, and 400Gb per slot with port counts ranging from 2×400Gb QSFP-DD to 8×100Gb QSFP28, meeting diverse bandwidth requirements.
Q
How do I choose the correct line card for my bandwidth requirements?
A
Select a line card based on aggregate capacity, port density, and interface type: use 400Gb cards for ultra-high throughput, 100/200Gb cards for mid-range demands, and optics compatibility.
Q
How do I upgrade or replace a module in Cisco 8000 Series?
A
Verify software and hardware compatibility, save the current configuration, power down if required, swap the module, power up, then validate with show platform and reload the config if needed.
Q
What power supply modules are supported on Cisco 8000 Series?
A
Cisco 8000 routers support redundant AC and DC power modules—3kW AC, 4kW AC, and -48V DC—with hot-swap capability and N+1 redundancy for high availability.
Q
How do I verify module compatibility before installation?
A
Use Cisco Feature Navigator or consult the hardware installation guide to cross-reference the router chassis model, software version, and module part numbers for full compatibility.
Q
Can I mix different module types in a single Cisco 8000 router?
A
Yes, Cisco 8000 Series chassis support mixed line cards and service modules within power and cooling limits, provided overall power and thermal budgets are not exceeded.
Q
What is the process for optical transceiver compatibility with Cisco 8000 Series?
A
Ensure transceivers are Cisco-qualified optics, match the line card’s port type (QSFP28, QSFP56, QSFP-DD), and check firmware support via the Cisco compatibility matrix.
Q
Do Cisco 8000 Series modules support advanced QoS features?
A
Yes, modules running Cisco IOS XR provide hardware-accelerated QoS with traffic policing, shaping, hierarchical scheduling, and class-based marking on all interface cards.
Q
How do I troubleshoot module discovery issues on Cisco 8000 Series?
A
Check slot LEDs, verify seating and power, run show platform hardware slot <slot> diagnostics, inspect syslog for errors, and confirm firmware levels match the router image.
Q
What licensing is required for modules on Cisco 8000 Series?
A
Most interface and line card features are covered under the Cisco IOS XR software license. Advanced features like segment routing or security services may require additional feature licenses.
Q
What cooling requirements exist for Cisco 8000 line cards?
A
Cisco 8000 routers use front-to-back airflow with hot-swap fans; ensure proper intake/output clearance, verify fan tray health, and maintain ambient temperatures per the installation guide.
Q
How do I update firmware on Cisco 8000 modules?
A
Use the Cisco IOS XR image install commands or Cisco Prime Infrastructure to stage and activate firmware on line cards and service modules without disrupting traffic (in-service upgrade).
Q
What warranty and support are available for Cisco 8000 Series modules?
A
Cisco provides a limited lifetime hardware warranty, software updates for the licensed IOS XR release, and optional Smart Net Total Care for 24×7 support, RMA services, and advanced replacement.
