C9300-NM-4M Catalyst 9300 4x 10G/mGig Copper Network Module

C9300-NM-4M is the Catalyst 9300 Series 4x Multigigabit Network Module, listed in Cisco's ordering table as the Catalyst 9300 4 x 10G/mGig copper Network Module, with C9300-NM-4M= as the spare.

It is one of the optional field-replaceable uplink modules for the Catalyst 9300; the default switch configuration does not include a network module, so one is chosen at purchase.

Cisco's compatibility note says Catalyst 3850 and Catalyst 9300 network modules are supported on Catalyst 9300 models, while Catalyst 9300X network modules work only on 9300X models; the 9300X equivalent is the C9300X-NM-8M.

Other C9300 modules in the same table are the 4x 1G C9300-NM-4G, 8x 10G/1G C9300-NM-8X, 2x 40G C9300-NM-2Q and 2x 25G/10G/1G C9300-NM-2Y.

Cisco lists an MTBF of 10,549,060 hours for the C9300-NM-4M.

Unused slots take the NM-BLANK-T1= Type 1 network module blank.

Fit check: a Catalyst 9300 (not 9300X) that needs copper multigigabit uplinks. For fibre uplinks see the C9300-NM-8X or C9300-NM-2Y; the Catalyst 9300 models, PoE and modules guide covers module choice and our Cisco Catalyst 2960, 3850 and 9300 hub lists switches.
