Q
What I/O modules are available for the Cisco Nexus 5000 series?
A
Cisco Nexus 5000 supports several I/O modules, including 24-port 10Gb SFP+, 48-port 1/10Gb SFP, and 40Gb QSFP+ modules, enabling flexible port density and speed combinations.
Q
Which optical transceiver modules are compatible with Cisco Nexus 5000 switches?
A
Cisco Nexus 5000 is certified for Cisco SFP, SFP+ and QSFP+ optics—such as SR, LR, LRM, and CWDM/DWDM variants—ensuring full interoperability and line-rate performance.
Q
Can I install Cisco Nexus 5000 modules without powering down the switch?
A
Yes. Cisco Nexus 5000 I/O modules are fully hot-swappable, allowing installation or removal without interrupting the switch’s operation or network connectivity.
Q
How do I verify module compatibility across Nexus 5000 chassis models?
A
Use the Cisco Nexus 5000 Hardware Installation Guide or Cisco’s compatibility matrix, which lists supported modules per chassis model and NX-OS version.
Q
What is the maximum port density per Cisco Nexus 5000 chassis?
A
A single Cisco Nexus 5000 chassis can host up to 48 10Gb ports or 12 40Gb ports, depending on the combination of installed I/O modules.
Q
Are there special power requirements for Nexus 5000 switch modules?
A
Each Nexus 5000 I/O module consumes between 45–60 W; verify total chassis power capacity and install redundant power supplies to meet peak load.
Q
How do I install an I/O module on a Cisco Nexus 5000 switch?
A
Align the module with the chassis slot rails, slide it in until it seats firmly, and secure the captive screws; the switch LED will indicate module readiness.
Q
What licensing is required for Nexus 5000 I/O modules?
A
All I/O modules operate under the base NX-OS license; advanced features like FCoE require the LAN Enterprise or Data Center license depending on your NX-OS release.
Q
Can I mix 10Gb and 40Gb modules in the same Nexus 5000 chassis?
A
Yes. Cisco Nexus 5000 supports mixed deployments of 10Gb SFP+ and 40Gb QSFP+ modules in different slots, subject to available module-slot mappings.
Q
How do I upgrade the firmware on a Nexus 5000 I/O module?
A
Use NX-OS ‘install all’ or ‘install module’ commands to push the unified fabric driver and module firmware from the bootflash image repository during maintenance windows.
Q
What diagnostics are available to verify module health?
A
The ‘show module’, ‘show hardware internal’ and ‘show diagnostic result module’ NX-OS commands report module status, temperature, voltage and self-test results.
Q
How does module redundancy work on Cisco Nexus 5000?
A
Deploy redundant I/O modules in paired slots and configure vPC or port-channel bundles to ensure path failover and uninterrupted traffic in case of module failure.
Q
Does the Nexus 5000 support Fibre Channel over Ethernet (FCoE) modules?
A
Yes. Cisco Nexus 5000 I/O modules support FCoE traffic natively over 10Gb SFP+ ports with the required Data Center license and NX-OS feature set.
Q
What is the typical forwarding latency for Nexus 5000 modules?
A
Cisco Nexus 5000 delivers sub-microsecond latency (around 600 ns) per port, making it suitable for low-latency data center and virtualization environments.
Q
How do I troubleshoot a module that fails to initialize?
A
Check module–chassis seating, review ‘show module’ for status codes, inspect syslog for errors, reseat the module, and verify NX-OS compatibility with the installed firmware.
Q
Can I monitor module power and cooling on the Nexus 5000?
A
Yes. Use ‘show environment all’ or the Cisco DCNM platform to monitor module intake/exhaust temperatures, fan speeds and power consumption in real time.
