UCSB-MLOM-40G-03 is the Cisco UCS VIC 1340 mLOM Virtual Interface Card with two internal 40G unified I/O ports for B200 M5 blade servers, B200 M3, and UCS B-Series M4 blades. The adapter gives Ethernet and FCoE connectivity through the chassis fabric path. The Cisco B200 M5 network adapter installs in the mLOM connection type and connects to the Fabric Interconnect through a Fabric Extender or directly through the UCS 6324 Fabric Connector in a UCS 5108 chassis. UCSB-MLOM-40G-04 is the VIC 1440 mLOM option for the same B200 M5 configuration, while this VIC 1340 keeps 1300 Series firmware behavior and 10/40G blade fabric modes.
UCSB-MLOM-40G-03 price for new stock is $55.59, a 14.6% saving from the Cisco list price of $65.12. UCSB-MLOM-40G-03 refurb price is $30.45. UCSB-MLOM-40G-03 is in stock and available for free next-day delivery. (terms applied)

Over 256 virtual interfaces present as NICs or HBAs, with about 8 reserved for internal use and OS or hypervisor limits reducing the usable count. PCIe Gen3 x16 host interface bandwidth feeds the mLOM mezzanine path. UCSB-MLOM-40G-03 takes UCS Manager Release 2.2(3) as its card management floor, while B200 M5 uses UCSM 3.2(2) as the recommended release. UCS Manager and Intersight manage the card. RoCE, VM-FEX, SR-IOV, VMQ, DPDK, usNIC, Cisco NetFlow, iSCSI Boot, VXLAN and NVGRE offloads are present. 12W typical power rises to 15W with the port expander card. 10°C to 35°C inlet temperature, 184 mm depth and 93 mm width set the blade thermal and mechanical match.
UCSB-MLOM-40G-03 is offered new sealed and certified refurbished. Certified refurbished units are inspected and bench-tested in a compatible host; board, connector and housing are inspected, recognized by a compatible host, and every port links at rated speed. Order UCSB-MLOM-PT-01 when the blade needs dual native 40G or dual 4 x 10GbE port-channeled mode. New sealed carries up to 3-year extended warranty, certified refurbished carries up to 1 year, and returns are 30 days on every condition; terms apply. Regional stock and RMA with advance replacement cover UK, EU, US and MEA buyers, with PO accepted and Net-30 for government.

A blade owner has a failed mLOM card in a B200 M5, B200 M3, or UCS B-Series M4 blade and must keep the same service profile design. The replacement line item should name UCSB-MLOM-40G-03 and the chassis fabric path before the PO.
A server expansion adds B200 M5 blades that need the same 10/40G unified I/O behavior as an existing VIC 1340 pool. The mLOM connection type is the required match, and UCSB-MLOM-40G-03 keeps the blade adapter family consistent.
A fabric refresh moves B200 M5 blades through Fabric Extenders or a UCS 6324 Fabric Connector in a UCS 5108 chassis. The buyer should match the Fabric Interconnect family, UCSM release, and port expander choice before ordering the adapter.
B200 M5 VIC 1480 pairing
B200 M5 cannot mix VIC 1340 with UCSB-VIC-M84-4P; select UCSB-MLOM-40G-04 for a B200 M5 build that needs the VIC 1480 rear mezzanine adapter.
Rear mezzanine VIC replacement
UCSB-MLOM-40G-03 is an mLOM adapter, not the rear mezzanine VIC; B200 M5 rear mezzanine replacement uses UCSB-VIC-M83-8P.

UCSB-MLOM-40G-03 is the Cisco UCS VIC 1340 modular LOM for blade servers and the Cisco UCS VIC 1340 model name. UCSB marks UCS B-Series, MLOM marks modular LOM, 40G marks the 40G class, and 03 separates the VIC 1340. UCSB-MLOM-40G-03= is the spare-order form.
UCSB-MLOM-40G-03 fits B200 M3, UCS B-Series M4 blade servers, and B200 M5. B200 M5 uses the mLOM connection type, and B200 M3 uses the dedicated VIC 1340/1240 slot. Before the PO, confirm the blade generation and mLOM slot on the chassis label.
A B200 M5 uses UCSB-MLOM-40G-03 as the Cisco UCS VIC 1340 mLOM option, or UCSB-MLOM-40G-04 as the VIC 1440 mLOM option. The same B200 M5 configuration also offers rear mezzanine VIC choices, with CPU and mix rules controlling those add-on cards.
UCSB-MLOM-40G-03 has two internal 40G unified I/O ports, 10/40G operating modes, an mLOM form factor, a PCIe Gen3 x16 host interface, 12W typical power, 15W with the port expander, 184 mm depth, and 93 mm width. The adapter runs in blade-server airflow.
UCSB-MLOM-40G-03 provides two internal 40G Ethernet unified I/O ports and dual 4 x 10GbE port-channeled operation. The far end must match the UCS blade fabric path through Fabric Extenders or the UCS 6324 Fabric Connector, not an external QSFP optic cage.
UCSB-MLOM-40G-03 needs UCSB-MLOM-PT-01 in the B200 M5 rear mezzanine connector for dual native 40G capability or dual 4 x 10GbE port-channeled mode. Without that port expander, the mLOM-only B200 M5 entries remain in the lower aggregate bandwidth configuration.
UCSB-MLOM-40G-03 uses the mLOM connection type in B200 M5 and the dedicated VIC 1340/1240 slot in B200 M3. Use one adapter per blade. The B200 M5 rear mezzanine connector remains separate and takes UCSB-MLOM-PT-01, UCSB-VIC-M83-8P, or UCSB-VIC-M84-4P.
UCSB-MLOM-40G-03 has a Cisco UCS Manager Release 2.2(3) card management floor. B200 M5 has UCSM 3.2(2) as the recommended release. UCS 6536 Fabric Interconnect use with 1300 Series VICs needs UCS 4.2(3). Management is through UCS Manager and Intersight.
UCSB-MLOM-40G-03 supports FCoE, RoCE, iSCSI Boot, VM-FEX, SR-IOV, VMQ, DPDK, usNIC, Cisco NetFlow, VXLAN, and NVGRE. Ethernet and FCoE share the same unified I/O fabric, so the service profile defines NIC and HBA personalities at boot time.
UCSB-MLOM-40G-03 is the base adapter part number. UCSB-MLOM-40G-03= is the spare-order form. Certified refurbished is an ORM condition, not the Cisco remanufactured form. Keep the exact supplied PID on the PO so the mLOM blade adapter is not replaced by a platform-coded part.
UCSB-MLOM-40G-03 is the VIC 1340 mLOM adapter, while UCSB-MLOM-40G-04 is the VIC 1440 mLOM adapter in the B200 M5 mLOM choices. Choose the VIC 1340 for 1300 Series continuity and choose the VIC 1440 when a B200 M5 build requires that newer mLOM option.
UCSB-MLOM-40G-03 fills the blade mLOM position, while UCSB-VIC-M83-8P is a rear mezzanine VIC 1380 adapter. The mLOM adapter is the base fabric connection. The rear mezzanine adapter adds another VIC position where the host configuration permits that slot and CPU rule.
Cisco stopped selling UCSB-MLOM-40G-03 on 30 October 2023. Cisco has not announced a last date of support for UCSB-MLOM-40G-03. B200 M5 server sales ended 30 October 2023, and Cisco service for the B200 M5 ends 31 October 2028.
ORM offers UCSB-MLOM-40G-03 new sealed with up to 3-year extended warranty and certified refurbished with up to 1 year. Returns are 30 days on every condition; terms apply. PO accepted, Net-30 for government, and RMA with advance replacement apply to this adapter.
