C9500-NM-8X Description

The C9500-NM-8X is a Cisco Catalyst 9500 Series network module for the uplink bay of C9500-16X and C9500-40X fixed switches. The module adds eight 1/10 Gigabit Ethernet SFP/SFP+ ports that accept standard SFP modules. It is not supported on C9500X-28C8D, C9500X-60L4D, C9500-32C, C9500-32QC, C9500-48Y4C or C9500-24Y4C, which use their fixed ports as the only uplinks.

Application Scenarios

10G Uplinks For A Distribution Switch

A C9500-16X serving as a building distribution switch gains eight 1/10G SFP/SFP+ ports for fiber links to access stacks or to the core.

Added Fiber Ports On Existing Switches

Where a C9500-40X already runs in a campus aggregation role, the module adds SFP/SFP+ ports for further fiber runs without a new switch.

C9500-NM-8X and C9500-NM-2Q fit the same uplink bays of the Catalyst 9500 base PIDs C9500-16X and C9500-40X, and port form separates them: C9500-NM-8X gives eight 1/10G SFP/SFP+ ports, while C9500-NM-2Q gives two 40G QSFP+ ports. Uplink plans built on 40G QSFP media need C9500-NM-2Q, and plans built from individual 1G or 10G SFP optics stay on C9500-NM-8X. A bay that will carry no data ports is filled with NM-C4-10G-BLANK, which has no Ethernet ports, because the switch should run with either a network module or a blank module installed. Neither module is used on C9500-24Y4C or C9500-48Y4C, which rely on their fixed QSFP28 uplinks.

Ordering Checklist

  • Catalyst 9500 hosts: Pair the module with C9500-16X and C9500-40X base switches. The switch should run with either a network module or a blank module installed.
  • Bundled switch PIDs: C9500-24X-A and C9500-24X-E already include the 8-port 10G SFP network module. A separate C9500-NM-8X line is for base switch orders only.

    No issues with customs or international shipping documentation. Would have liked a tracking update sooner, but the product is great.

Questions & Answers

  • Which fan does C9500-40X-E need when it carries C9500-NM-8X?

    FAN-T4-R, the Catalyst 9500 Type 4 front to back cooling fan listed for C9500-40X-E, C9500-16X-A and C9500-16X-E. Per the Catalyst 9500 ordering guide, these hosts take PWR-C4-950WAC-R or PWR-C4-950WAC-R/2 as redundant supplies. PWR-C4-BLANK covers an empty supply slot. Order the fan as a spare with the module.
  • What switching capacity does C9500-16X-E have with C9500-NM-8X in its module slot?

    C9500-16X-A and C9500-16X-E are rated at 480 Gbps and 360 Mpps, with 16 SFP+ ports and one network module slot. C9500-NM-8X fills that single slot. The 16 fixed SFP+ ports stay in service when the module is fitted. Cisco lists these figures in its Catalyst series catalog.
  • Is C9500-NM-8X hot-swappable, and which blank covers an empty bay?

    Yes. C9500-NM-8X is a hot-swappable network module, and its spare PID is C9500-NM-8X=. If the uplink bay is left empty, fit NM-C4-10G-BLANK to keep airflow through the bay. The module goes in C9500-16X-A, C9500-16X-E and C9500-40X-E base switches only, and the switch should run with a module or a blank installed.
  • Which media can the eight ports of C9500-NM-8X use?

    The eight ports of C9500-NM-8X are 1/10 Gigabit Ethernet SFP/SFP+ ports that accept standard SFP modules. The module appears in the Cisco IOS XE Fuji 16.8.x supported hardware listing. It does not work in the Catalyst 9500 models that use their fixed ports as the only uplinks, so check the host switch first.
