C9300X-NM-8M= Cisco Catalyst 9300X 8-Port Multigigabit Network Module

BRAND NEW WITH FULL CISCO WARRANTY!!!

The Cisco Catalyst 9300X Network Module C9300X-NM-8M= is a field-replaceable expansion module designed specifically for compatible Cisco Catalyst 9300X Series switches. It adds eight 10G/mGigabit copper Ethernet ports, allowing organizations to extend switch connectivity with flexible multigigabit speeds of 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, and 10 Gbps. Cisco identifies the C9300X-NM-8M= as the spare version of the C9300X-NM-8M network module.

The module is intended for enterprise networks that need additional high-speed copper connectivity without replacing the underlying Catalyst 9300X switch. Its multigigabit capability is particularly useful for modern access networks where wireless access points, servers, workstations, and other endpoints require more bandwidth than traditional Gigabit Ethernet can provide. Because it is a field-replaceable network module, businesses can expand the capabilities of supported Catalyst 9300X platforms while protecting their existing infrastructure investment.

FAQs – Cisco Catalyst 9300X Network Module C9300X-NM-8M=

1. What does the C9300X-NM-8M= add to a Catalyst 9300X switch?

It adds eight multigigabit copper Ethernet ports capable of operating at 100 Mbps, 1 Gbps, 2.5 Gbps, 5 Gbps, or 10 Gbps, providing additional high-speed connectivity for compatible Catalyst 9300X switches.

2. Which Cisco switches are compatible with the C9300X-NM-8M=?

The module belongs to the Catalyst 9300X network-module family. Cisco specifies that Catalyst 9300X network modules are supported only on Catalyst 9300X models.

3. Can the C9300X-NM-8M= be upgraded or expanded?

The module itself provides a fixed eight-port configuration. Expansion is achieved by installing the appropriate compatible network module into a supported Catalyst 9300X switch rather than adding ports to the C9300X-NM-8M= itself.

4. Does the module have its own power supply?

No. The C9300X-NM-8M= is a network expansion module and does not use an independent AC power supply. It receives power through the host Catalyst 9300X switch.

5. Can the module be installed without a Catalyst 9300X switch?

No. It is a field-replaceable network module designed to operate within a compatible Catalyst 9300X chassis. It is not a standalone Ethernet switch.

6. What is the main advantage of the multigigabit ports?

The eight copper interfaces support multiple Ethernet speeds up to 10 Gbps, allowing organizations to connect devices such as high-performance wireless access points and other bandwidth-intensive endpoints while maintaining copper-based infrastructure.
