Which Catalyst 9300X switches accept C9300X-NM-8M?

C9300X-NM-8M is a field-replaceable network module that installs in the uplink slot of Catalyst 9300X Series switches. Standard Catalyst 9300 models do not support the module and its eight Multigigabit Ethernet copper ports.

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

C9300X-NM-8M needs Cisco IOS XE Bengaluru 17.5.1 or later, the first release that supports the module. Standard Catalyst 9300 switches do not support it, so the host must be a Catalyst 9300X switch running that release or later.

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

In the Catalyst 9300 datasheet power table at 115Vac and 100% PoE load with a Platinum supply, the switch draws 694.4W with no module and 716.6W with C9300X-NM-8M installed. The module ports carry no PoE, because Cisco notes that uplink modules do not power devices.

How many C9300X-NM-8M ports work on a C9300X-48HXN-A or C9300X-48HXN-E?

Only part of the module works on this host, and the usable count depends on the Cisco IOS XE release. The specifications list ports disabled on the HXN models, so plan for fewer active multigigabit uplinks when the module is fitted to this switch.

Which PID do I order as a spare for C9300X-NM-8M?

Order the spare PID C9300X-NM-8M=. It is a field-replaceable network module with eight Multigigabit Ethernet copper ports, listed by Cisco as a Catalyst 9300X copper network module. The spare fits Catalyst 9300X switches only, so confirm the host before ordering.

Does C9300X-NM-8M work in a standard Catalyst 9300 switch?

No. The specifications state that the standard C9300 models are not supported for C9300X-NM-8M. It installs in the X-series switches only, and the standard switches use their own network module family, which is a separate part number.

C9300X-NM-8M Description

The C9300X-NM-8M is a Cisco Catalyst 9300X network module for copper multigigabit uplinks. It provides eight Multigigabit Ethernet copper ports at 10G and 1G and installs in the uplink slot of Catalyst 9300X switches. Standard Catalyst 9300 switches do not support it, and Cisco IOS XE Bengaluru 17.5.1 is the first release that does.

Application Scenarios

Copper Uplinks Without Fiber

A building that already has Cat 6A runs between the access closet and the aggregation room uses the eight copper ports as 10G uplinks without adding optics.

Multigigabit Server And Device Ports

An edge room can use the module ports to attach multigigabit servers or appliances directly to a Catalyst 9300X switch alongside its regular downlinks.

C9300X-NM-8M is the copper module of this group, with eight 10G/1G multigigabit ports on Ethernet cabling, while C9300X-NM-8Y has eight SFP28 ports for 25G, 10G or 1G optics. Uplinks that run on fiber or DAC at 25G need C9300X-NM-8Y. Aggregation links at 40G or 100G need C9300X-NM-2C with two QSFP ports, or C9300X-NM-4C with four ports on C9300X-24Y, C9300X-48HX or C9300X-48TX. Both modules were introduced in Cisco IOS XE 17.5.1.

Ordering Checklist

Catalyst 9300X hosts: Use the module in Catalyst 9300X modular-uplink switches, including the 48-port 10G/mGig and 24-port 25G models. It fits only Catalyst 9300X switches; standard Catalyst 9300 models take C9300-NM modules instead.
C9300X-48HXN hosts: C9300X-48HXN accepts C9300X-NM modules with a reduced port count. Not every module port is usable on this host.

They flagged a detail we missed in our spec. Saved us from ordering wrong. Invoice formatting was a bit different from what our AP system expects, but workable.
