C3850-NM-2-10G is the Cisco Catalyst 3850 uplink network module engineered for deployments that require a mixed Gigabit and 10 Gigabit uplink profile in the switch network-module bay. It installs exclusively in supported Cisco Catalyst 3850 switches, including WS-C3850-24T/P/U, WS-C3850-48T/F/P/U, WS-C3850-12X48U, WS-C3850-24XU, WS-C3850-12S, and WS-C3850-24S models. The module occupies the proprietary front uplink slot and presents SFP/SFP+ receptacles for fiber or supported Cisco pluggable optics, enabling flexible transceiver deployment. Its intelligent layout provides the access switch with native Gigabit handoff positions plus a dedicated 10G uplink tier for high-capacity distribution connectivity. In contrast, the C3850-NM-4-10G provides four 10G-capable uplink slots, while this model maintains the two-port 10G tier specifically designed for lower-density uplink architectures and cost-optimized deployments.
10GbE operates on the two right-side SFP+ slots, while 1GbE operates on the two left-side SFP slots for flexible mixed uplink assignments and network flexibility. Four valid interfaces appear in the switch configuration: GigabitEthernet1/1/1 through GigabitEthernet1/1/2 and TenGigabitEthernet1/1/3 through TenGigabitEthernet1/1/4, providing straightforward port identification. The SFP+ positions also operate seamlessly with 1G SFP optics, allowing networks to maintain Gigabit fiber connectivity during staged migration paths and technology transitions. The C3850-NM-2-10G includes comprehensive front-panel port-status LEDs for link state monitoring, activity indication, fault detection, and disabled conditions, enhancing visibility and troubleshooting capability. The host Catalyst 3850 software manages trunks, routed interfaces, EtherChannel configurations, VLAN transport, and automatic optics recognition, making deployment planning closely tied to the switch image version, transceiver compatibility support lists, and upstream port design requirements.
The C3850-NM-2-10G installs in the Catalyst 3850 network-module bay and Cisco documents the network module as hot-swappable when proper removal and insertion procedures are strictly followed. Engineers must remove connected cables and SFP/SFP+ modules before installation, secure the captive screws firmly, and then verify module detection and interface state through the switch command-line interface. ORM Systems supplies this module in new and certified refurbished conditions, with all refurbished units thoroughly inspected for connector condition, faceplate integrity, EEPROM recognition capability, and functional operation in compatible Catalyst 3850 chassis environments. Request this module for equipment replacement strategies, spare inventory holding, or multi-site Catalyst 3850 uplink standardization initiatives where two 10G-capable uplinks align precisely with traditional access-to-distribution network design patterns.
C3850-NM-2-10G price is $1,037.00, a 77.5% saving from the Cisco list price of $4,612.00. C3850-NM-2-10G is in stock and available for next-day dispatch. (terms applied)

C3850-NM-2-10G sits in the modular uplink slot of a compatible Catalyst 3850 access switch and presents two 10GE SFP+ links toward distribution. Engineers attach supported SFP+ optics, map each uplink to a separate upstream switch, and configure trunks, routed ports, or EtherChannel according to the campus design. The module keeps endpoint switching on the host chassis while moving northbound traffic over 10G paths. The result is a cleaner access-to-distribution handoff with higher uplink capacity and controlled redundancy.
A Catalyst 3850 stack uses C3850-NM-2-10G to carry aggregated closet traffic from multiple stack members over two 10GE uplinks. Network teams place the module in the selected stack member, install matched SFP+ optics, and configure resilient uplink paths from the stack toward distribution. User, voice, wireless, and camera VLANs remain on the access switches while the uplink module handles northbound transport. The result is simplified closet growth with fewer 1G uplinks and a more predictable 10G exit path.
C3850-NM-2-10G supports migration from 1G uplink designs to 10G aggregation without replacing the compatible Catalyst 3850 access switch. Engineers install the two-port network module, move selected uplinks onto SFP+ optics, and update spanning tree, routing, or port-channel settings to match the upstream architecture. The module gives the existing switch a defined 10G handoff point while preserving access-port cabling and switch configuration. The result is a staged bandwidth upgrade with lower disruption to established access-layer operations.

Cisco C3850-NM-2-10G is a Catalyst 3850 network module that adds two 10 Gigabit Ethernet uplink ports to compatible Cisco Catalyst 3850 switches. It is used when a 3850 access switch needs higher-speed fiber uplinks to distribution, aggregation, or core switching layers. The module fits the modular uplink slot on supported Catalyst 3850 models.
C3850-NM-2-10G identifies a Cisco Catalyst 3850 network module with two 10G uplink ports. In the model number, C3850 points to the Catalyst 3850 platform, NM means network module, 2 indicates two uplink interfaces, and 10G refers to 10 Gigabit Ethernet connectivity. The SKU helps buyers distinguish it from 1G, 4-port 10G, and 40G modules.
C3850-NM-2-10G is a network module, not a standalone switch. It installs into a compatible Cisco Catalyst 3850 switch and provides two 10GE uplink ports for fiber or SFP+ based connectivity. The host switch supplies switching, software, power, and management, while the module extends uplink capacity from the access layer.
C3850-NM-2-10G sits in the Cisco Catalyst 3850 modular uplink family. It is positioned above 1G uplink modules and below higher-density 10G or 40G options such as C3850-NM-4-10G, C3850-NM-8-10G, and C3850-NM-2-40G. It suits deployments that need two 10G uplinks without filling the chassis with extra unused uplink capacity.
C3850-NM-2-10G provides two 10 Gigabit Ethernet uplink ports. These ports are normally used with SFP+ transceivers or compatible direct attach cabling, depending on the switch design and supported Cisco optics. The two-port layout is useful for redundant uplinks, EtherChannel designs, or separate routed links from a Catalyst 3850 access switch.
C3850-NM-2-10G uses 10GE SFP+ uplink interfaces. The ports support modular optics rather than fixed copper interfaces, so network teams select the correct SFP+ transceiver or cable for the fiber plant, reach, and upstream switch. Common design checks include optic compatibility, software support, fiber type, and link speed requirements before ordering.
C3850-NM-2-10G does not add PoE access ports. It is an uplink module for the Cisco Catalyst 3850 platform and provides two 10GE uplink interfaces. PoE, PoE+, or access-port capability comes from the host Catalyst 3850 switch model, while this module handles higher-speed northbound connectivity toward distribution or aggregation switches.
C3850-NM-2-10G participates in Layer 2 or Layer 3 designs through the host Cisco Catalyst 3850 switch and its installed software feature set. The module provides the physical 10GE uplink interfaces, while VLAN trunks, routed ports, EtherChannel, access control, and routing behavior are configured on the switch operating system.
C3850-NM-2-10G is described as a hot-swappable Catalyst 3850 network module, allowing replacement with reduced disruption when the switch platform and operating procedure support it. Network teams should still follow Cisco maintenance guidance, save configurations, validate optics, and schedule controlled change windows for production environments where uplink removal affects traffic paths.
C3850-NM-2-10G works with Catalyst 3850 switches that support StackWise operation, but the module itself is not a stacking module. It provides two 10GE uplinks from the switch or stack toward upstream infrastructure. Stack behavior, stack bandwidth, and stack member management are handled by the Catalyst 3850 platform and its stacking hardware.
C3850-NM-2-10G is used to give a Cisco Catalyst 3850 switch two 10G uplinks for higher-speed connectivity beyond the access layer. Typical designs connect the module to distribution switches, aggregation switches, or collapsed core switches. It supports redundant uplink paths, 10G fiber handoff, and cleaner migration from 1G uplinks where access traffic has increased.
C3850-NM-2-10G suits small to mid-sized Catalyst 3850 deployments that need two 10G uplinks from an access switch or wiring closet. It is often enough for dual-homed uplink designs, moderate aggregation traffic, or branch network closets. Higher-density uplink environments usually compare it with C3850-NM-4-10G or C3850-NM-8-10G.
C3850-NM-2-10G suits access-layer workloads that need faster northbound capacity than 1G uplinks provide. Examples include dense user access, wireless access point aggregation, IP camera traffic, voice and data VLANs, and server or storage-adjacent access designs. The module gives the Catalyst 3850 two 10G paths for trunking, routing, or link aggregation.
C3850-NM-2-10G works well in redundant uplink designs because it provides two 10GE interfaces from the host Catalyst 3850 switch. Engineers commonly use one link to each distribution switch, or bundle both ports in an EtherChannel where the upstream design supports it. The final behavior depends on switch configuration, topology, optics, and software features.
C3850-NM-2-10G is designed for compatible Cisco Catalyst 3850 switches with a modular uplink slot. Buyers should verify the exact Catalyst 3850 switch model, Cisco IOS XE release, and module support matrix before ordering. It is not intended for Catalyst 3650, Catalyst 9300, Catalyst 9200, or Catalyst 9500 switch module slots.
C3850-NM-2-10G uses 10GE SFP+ uplink ports, so compatible Cisco SFP+ optics are selected according to reach and media type. Common 10G options in Catalyst environments include SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber. Compatibility should be checked against the Catalyst 3850 software release and Cisco transceiver support guidance.
C3850-NM-2-10G connects Catalyst 3850 access switches to Cisco distribution platforms that accept compatible 10GE SFP+ links. Common upstream platforms include Catalyst 4500-X, Catalyst 6500, Catalyst 6800, Catalyst 9300, Catalyst 9400, and Catalyst 9500, depending on the network generation. Optic type, fiber media, and link configuration must match at both ends.
Buyers should check the host Catalyst 3850 switch model, uplink slot availability, Cisco IOS XE version, optic requirements, fiber type, and target uplink speed before ordering C3850-NM-2-10G. ORM Systems can quote the module with compatible SFP+ optics where required, helping reduce mismatch risk between the module, transceivers, and upstream switch ports.
C3850-NM-2-10G provides two 10GE uplink ports, while C3850-NM-4-1G provides four 1G uplink ports. The 2-port 10G module suits designs that need higher uplink bandwidth with fewer physical links. C3850-NM-4-1G suits lower-bandwidth environments where 1G fiber uplinks are still enough for the access switch.
C3850-NM-2-10G offers two 10GE uplink ports, while C3850-NM-4-10G offers four 10GE uplink ports. The 2-port module is suitable for dual-uplink access designs. The 4-port module fits higher-density uplink needs, additional EtherChannel members, or designs that require separate 10G links to more upstream devices.
C3850-NM-2-10G is a lower-density 10G uplink option than C3850-NM-8-10G. It provides two 10GE ports for standard redundant uplink designs, while C3850-NM-8-10G supports more 10G uplink interfaces for larger aggregation needs. Buyers should confirm host switch support because not every Catalyst 3850 chassis supports every uplink module.
C3850-NM-2-10G provides two 10GE SFP+ uplinks, while C3850-NM-2-40G is used for two 40GE uplink ports on supported Catalyst 3850 models. The 10G module fits access-to-distribution links where 10G is sufficient. The 40G module targets higher aggregation capacity and requires matching 40G optics, cabling, and upstream ports.
