C9300-NM-4G is a Cisco Catalyst 9300 uplink network module with four 1G Gigabit Ethernet SFP interfaces for access-switch uplink expansion. It installs in the front network module slot of compatible Cisco Catalyst 9300 Series switches that support modular uplink hardware. The module gives network teams a 1G fiber handoff option for access closets that do not require 10G, 25G, or 40G uplinks. C9300-NM-8X differs by providing eight 10G SFP+ uplink ports for higher-bandwidth Catalyst 9300 designs.
1GbE link speed supports standard Gigabit Ethernet uplinks from the host Catalyst 9300 switch toward distribution, aggregation, or routed upstream devices. Four SFP interfaces provide separate physical paths for trunks, routed links, or EtherChannel designs where the upstream architecture still uses 1G fiber. IEEE 802.3z Gigabit Ethernet operation depends on the installed SFP optics and the supported software state of the host switch. C9300-NM-4G operates as a passive uplink expansion module controlled through Cisco IOS XE on the Catalyst 9300 chassis.
The module slides into the Catalyst 9300 network module bay and presents its interfaces to the host switch for normal interface configuration, monitoring, and operational control. Network module recognition, interface availability, and supported optics depend on the switch model, IOS XE release, and Cisco compatibility guidance. C9300-NM-4G is available through ORM Systems in new and certified refurbished supply options, with refurbished units inspected for connector condition and functionally tested in a compatible Catalyst 9300 host. ORM Systems supports quote requests for single replacements, spare stock, and fleet-wide 1G uplink standardisation projects.
C9300-NM-4G price is $225.00, a 64.7% saving from the Cisco list price of $637.00. C9300-NM-4G is in stock and available for next-day dispatch. (terms applied)

C9300-NM-4G sits in the modular uplink slot of a compatible Catalyst 9300 access switch and presents four 1G Gigabit Ethernet interfaces northbound. Engineers map those interfaces to distribution trunks, routed uplinks, or EtherChannel bundles according to the campus design. The module keeps fixed endpoint ports separate from upstream handoff planning, which simplifies access-layer refreshes where 1G distribution links remain in service. The result is a Catalyst 9300 access block with defined Gigabit uplink capacity and cleaner separation between endpoint access and distribution connectivity.
In a Catalyst 9300 stack, C9300-NM-4G provides four 1G uplink ports from the installed switch member into the wider distribution layer. Network teams assign the module interfaces to redundant uplink paths, trunk groups, or routed links while StackWise keeps the access block under one management plane. The four-port layout supports separate uplinks for resilience, traffic segmentation, or staged migration. The result is a stacked access design with controlled Gigabit handoff points and less dependence on fixed front-panel access ports.
The module supports Catalyst 9300 deployments that refresh the access switch while preserving existing 1G distribution connectivity. Engineers install C9300-NM-4G in the new access switch, reconnect established Gigabit uplinks, and then migrate VLAN trunks, routed interfaces, or EtherChannel settings onto the replacement platform. This role matters where upstream distribution switches, fiber paths, or patching standards remain built around 1G links. The result is an access-layer hardware upgrade that keeps the current distribution handoff intact during a controlled migration.

C9300-NM-4G is a Cisco Catalyst 9300 network module that adds four 1G Gigabit Ethernet uplink ports to compatible Catalyst 9300 switches. It is used when an access switch needs additional Gigabit uplink connectivity without replacing the base switch. The module fits the modular uplink bay on supported Catalyst 9300 models.
The C9300-NM-4G model number identifies a Catalyst 9300 network module. C9300 refers to the Cisco Catalyst 9300 switching family, NM indicates network module, and 4G indicates four Gigabit Ethernet ports. The SKU is commonly selected for 1G uplink expansion in Catalyst 9300 access-layer deployments.
C9300-NM-4G is an expansion network module, not a standalone switch. It installs into a compatible Cisco Catalyst 9300 switch and provides four additional 1G Gigabit Ethernet uplink ports. The switching, routing, management, and software functions remain handled by the host Catalyst 9300 switch.
C9300-NM-4G sits in the Catalyst 9300 modular uplink family as the four-port 1G Gigabit Ethernet option. It is suited to access switches that connect upstream at 1G speeds rather than requiring higher-speed 10G, 25G, or 40G uplinks. It supports practical uplink expansion for standard campus access designs.
C9300-NM-4G provides four 1G Gigabit Ethernet ports for compatible Cisco Catalyst 9300 switches. These ports are used primarily for uplinks to distribution switches, aggregation devices, or network core paths where 1G connectivity is sufficient. The module keeps uplink connectivity separate from the fixed access ports on the switch.
C9300-NM-4G supports 1G Gigabit Ethernet connectivity across four ports. It is designed for environments where the Catalyst 9300 switch needs Gigabit uplinks rather than 10G or higher-speed uplink modules. This makes it suitable for access closets, smaller aggregation paths, and legacy distribution connections that still operate at 1G.
C9300-NM-4G does not provide PoE because it is an uplink network module, not an endpoint access-port module. PoE delivery remains a function of the host Catalyst 9300 switch model and its power supplies. The C9300-NM-4G module is used for Gigabit Ethernet uplink connectivity from that switch.
C9300-NM-4G adds physical 1G uplink ports, while Layer 2 and Layer 3 features are controlled by the host Catalyst 9300 switch software and license. VLAN trunks, routed links, EtherChannel, and policy behavior depend on the switch configuration. The module supplies the uplink interfaces used by those designs.
C9300-NM-4G is managed through the host Cisco Catalyst 9300 switch, not as a separate device. Network teams configure the module ports through the switch CLI, Cisco IOS XE software, and supported Cisco management platforms. Interface status, speed, VLAN assignments, trunks, and routing configuration appear as part of the switch.
C9300-NM-4G does not provide switch stacking by itself. Catalyst 9300 stacking is handled by the compatible host switches and StackWise components. The module provides four 1G uplink ports that operate within the switch or stack configuration, allowing uplinks to be planned per switch or across a stacked access block.
C9300-NM-4G is used to add four 1G uplinks to a Cisco Catalyst 9300 access switch. It commonly connects access-layer switches to distribution switches, aggregation switches, firewalls, or routed upstream links. The module is useful when the installed switch chassis has the required access ports but needs separate Gigabit uplink capacity.
C9300-NM-4G suits small to midsize access-layer environments or larger networks that still use 1G distribution uplinks. It fits wiring closets where Catalyst 9300 switches serve endpoints and require multiple Gigabit handoffs upstream. Environments planning 10G, 25G, or 40G uplinks should compare higher-speed Catalyst 9300 network modules.
C9300-NM-4G suits general campus access traffic, user connectivity, printer networks, access points, phones, cameras, and branch uplink paths where 1G bandwidth meets design requirements. The module supports practical northbound connectivity from the Catalyst 9300 switch. Higher-volume aggregation, dense wireless, or data-heavy environments often require faster uplink modules.
C9300-NM-4G is suitable for compatible Catalyst 9300 stack deployments when each installed switch needs 1G uplink interfaces. Network teams use the module ports for uplink diversity, EtherChannel design, or distribution handoff planning. Stack operation remains controlled by the Catalyst 9300 switches and supported StackWise configuration.
C9300-NM-4G is designed for compatible Cisco Catalyst 9300 Series switches with a modular uplink slot. It is not a universal module for every Catalyst platform. Buyers should match the module against the exact Catalyst 9300 switch model, Cisco compatibility documentation, and the required uplink design before ordering.
C9300-NM-4G is for the Cisco Catalyst 9300 network module family and should not be treated as a Catalyst 9200 module. Catalyst 9200 and Catalyst 9200L platforms use their own supported uplink options. Compatibility should be checked against the exact switch SKU before using this module in a refresh or replacement project.
C9300-NM-4G ports commonly carry standard Ethernet configurations such as VLAN trunks, access uplinks, routed interfaces, and EtherChannel, depending on the host Catalyst 9300 software and license. The module provides the physical 1G interfaces, while Cisco IOS XE on the switch controls protocol behavior, monitoring, and operational policy.
C9300-NM-4G operates inside the managed Catalyst 9300 switch, so integration follows the host switch management model. Cisco DNA Center or other Cisco management tools view and configure the switch interfaces according to supported Catalyst 9300 software. The module itself does not require a separate management system or independent license.
C9300-NM-4G provides four 1G Gigabit Ethernet ports, while C9300-NM-8X is used when a Catalyst 9300 deployment requires higher-density 10G SFP+ uplinks. C9300-NM-4G fits 1G distribution environments and cost-controlled refreshes. C9300-NM-8X is better suited to higher-bandwidth aggregation or campus designs moving beyond Gigabit uplinks.
C9300-NM-4G serves four 1G uplink connections, while C9300-NM-2Y is a higher-speed Catalyst 9300 module with two 25G SFP28 ports. C9300-NM-4G is appropriate for Gigabit access-to-distribution handoffs. C9300-NM-2Y fits networks that need fewer physical uplinks but much higher uplink bandwidth per port.
C9300-NM-4G targets four 1G Gigabit Ethernet uplinks, while C9300-NM-2Q targets two 40G QSFP+ uplinks in Catalyst 9300 designs. The 4G module fits access closets using Gigabit distribution links. The 2Q module fits aggregation-heavy designs where uplink bandwidth, not port count, is the main design requirement.
C9300-NM-4G provides four 1G Gigabit Ethernet uplinks, while C9300-NM-4M is used for multigigabit uplink requirements in compatible Catalyst 9300 deployments. C9300-NM-4G fits standard Gigabit upstream connectivity. C9300-NM-4M is more suitable where the upstream design requires speeds above traditional 1G on supported media.

ORM Systems can supply tested refurbished enterprise hardware where available. Testing helps reduce deployment risk when the module is being installed into an existing Catalyst 9300 switch or access stack.
C9300-NM-4G follows the compliance and platform requirements associated with Cisco Catalyst 9300 hardware. Exact regulatory and environmental certifications should be verified against Cisco documentation for the specific module and host switch combination. Buyers should confirm compliance needs when purchasing for controlled procurement, public sector, or audited infrastructure environments.
C9300-NM-4G installs into the modular network module slot of a compatible Cisco Catalyst 9300 switch. Installation should follow Cisco hardware guidance for the exact switch model. After installation, network teams verify that the host switch detects the module and then configure the four 1G interfaces for the intended uplink design.
C9300-NM-4G does not operate with a separate standalone software license. The host Cisco Catalyst 9300 switch software image and license determine available switching, routing, automation, and management features. The module provides physical 1G uplink interfaces that are configured within the same operating environment as the switch.
C9300-NM-4G requires a compatible Catalyst 9300 switch with the proper network module slot. The deployment may also require suitable 1G cabling or optics, depending on the port type and upstream connection design. Network teams should confirm media, interface configuration, spare slot availability, and software compatibility before installation.
