C9300X-NM-8Y Description

The C9300X-NM-8Y is a Cisco Catalyst 9300X Series network module for access switches that uplink to distribution or aggregation layers over fiber. The module has eight SFP28 ports that run at 25G, 10G or 1G, and it is hot-swappable with Cisco-supported SFP, SFP+ or SFP28 transceivers. The module fits Catalyst 9300X switches only, and on Catalyst 9300X HXN models ports 1 to 6 are usable on Cisco IOS XE 17.8.1 and later while ports 7 and 8 are disabled.

Application Scenarios

25G Uplinks From An Access Closet

A Catalyst 9300X switch in a wiring closet reaches the distribution layer over 25G fiber from the eight SFP28 ports of the module. The uplink gains headroom over 10G modules without replacing the switch.

Mixed-Speed Fiber Aggregation

Where some uplink runs still use 10G or 1G optics, the module terminates them next to 25G links, because its ports accept SFP, SFP+ and SFP28 transceivers. Speeds can be moved up link by link as the aggregation switches change.

C9300X-NM-8Y gives a Catalyst 9300X switch eight SFP28 uplink ports at 25G, 10G or 1G over fiber, while C9300X-NM-8M has eight multigigabit copper ports, so fiber uplinks point to C9300X-NM-8Y and copper cabling to C9300X-NM-8M. Uplinks above 25G need C9300X-NM-2C with two 100G/40G QSFP28 ports, or C9300X-NM-4C with four, which Cisco lists only for C9300X-48HX, C9300X-48TX and C9300X-24Y. On a C9300X-48HXN, C9300X-NM-8Y exposes ports 1 to 6 and C9300X-NM-2C exposes ports 1 and 2. None of these modules fit a standard Catalyst 9300 switch.

Ordering Checklist

  • Catalyst 9300X hosts: Use the module in C9300X-12Y, C9300X-24Y, C9300X-48TX, C9300X-48HX, C9300X-48HXN or C9300X-24HX. C9300X-NM modules work only in Catalyst 9300X switches; standard Catalyst 9300 models take C9300-NM modules.
  • Catalyst 9300X-HXN hosts: C9300X-48HXN takes C9300X-NM-8Y, but C9300X-NM modules expose fewer ports on this model.

    Layer23 fits the profile of a strategic supplier perfectly. Would have liked a tracking update sooner, but the product is great.

Questions & Answers

  • Which Catalyst 9300X switches accept C9300X-NM-8Y?

    C9300X-NM-8Y installs in C9300X-12Y-A, C9300X-12Y-E, C9300X-24Y-A, C9300X-24Y-E, C9300X-48TX-A, C9300X-48TX-E, C9300X-48HX-A, C9300X-48HX-E, C9300X-48HXN-A, C9300X-48HXN-E, C9300X-24HX-A or C9300X-24HX-E. C9300X-NM modules work only in Catalyst 9300X switches, and the module is hot swappable with eight SFP28 ports.

  • Which Cisco IOS XE release does C9300X-NM-8Y need?

    C9300X-NM-8Y needs Cisco IOS XE Bengaluru 17.5.1 or later. Standard Catalyst 9300 switches do not take the module, so the host must be a Catalyst 9300X switch that is running that release or a later one.

  • How much does the Catalyst 9300X input power change with C9300X-NM-8Y installed?

    In the Catalyst 9300 datasheet power table with the 715WAC-P Platinum supply at 115Vac and full port traffic, the switch draws 315.0W with C9300X-NM-8Y installed and 276.7W with no module. The uplink module ports carry no PoE, per Cisco.

  • Which C9300X-NM-8Y ports are usable on a C9300X-48HXN-E running Cisco IOS XE 17.8.1 or later?

    Ports 1 to 6 are usable and ports 7 and 8 are permanently disabled, per the Catalyst 9300 hardware installation guide. C9300X-48HXN-A and C9300X-48HXN-E first shipped on Cisco IOS XE 17.9.3, so this later behaviour is the one a new switch runs.

  • Can C9300X-NM-8Y be hot-swapped with transceivers installed?

    Yes, C9300X-NM-8Y is hot swappable. It accepts Cisco-supported SFP, SFP+ or SFP28 transceivers in its eight ports, and each port can run at its own speed. Confirm the transceiver list for the Catalyst 9300X host before inserting optics.

  • Does C9300X-NM-8Y have a hot-swappable replacement unit?

    Yes, the spare unit is ordered as C9300X-NM-8Y=. Because the module is hot swappable, a failed unit can be replaced while the Catalyst 9300X switch stays powered. Remove the transceivers and cables from the old module first, then move them to the new one.
