UCS-PSU-6248UP-AC is a 750W AC internal power supply for the UCS 6248 UP fabric interconnect, with hot-swap service in the two-bay chassis. The module takes 90-264V AC and supports redundant operation when a second matching AC unit is installed. A Cisco UCS 6248 UP power supply replacement starts with a failed front bay module; this part fits the UCS 6248 UP, not the UCS 6296 UP. A single supply runs the fabric interconnect, and two supplies provide redundancy across separate power sources. The AC fabric interconnect power supply uses port-side exhaust airflow, so fan modules and power supplies must match the same direction. UCS-PSU-6248UP-DC is the -48V DC version for DC sites.

750W maximum output at 12V DC sets the upper power rating for the front bay. 390W at 110V AC makes low-line circuits a sizing check before a replacement order. 90-264V AC input and 50 to 60 Hz service fit standard data center AC feeds, while North American installations require a 15A or 20A circuit. 2497 BTU/hr at 600W sets the rack cooling allowance for each installed module. UCS-PSU-6248UP-AC reports normal operation with a green power supply status LED and fault conditions with the fault LED. Each power supply has a separate power cord with an IEC C13 equipment connector. Use N10-S1BLKP= in an empty second power bay.
UCS-PSU-6248UP-AC is available as new sealed or certified refurbished. Certified refurbished units are inspected and bench-tested in a compatible host or on a load tester; housing, latch and connector pins are inspected, output holds rated voltage under load, status LEDs report normal, and hot insertion and removal are verified in a live host. Order new sealed for sealed spares and certified refurbished for post-support replacement. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and 30-day returns apply. UK, EU, US and MEA stock supports RMA with advance replacement; PO accepted and Net-30 for government.

The UCS 6248 UP fabric interconnect passed Cisco service on 31 May 2024, so AC spare pools need this exact PID. Specify UCS-PSU-6248UP-AC for AC bays, confirm port-side exhaust on the chassis label, and choose certified refurbished when Cisco support coverage is no longer active.
A front power bay with a failed AC module needs the same UCS 6248 UP power supply family. Specify UCS-PSU-6248UP-AC for 90-264V AC feeds, keep the second supply installed during hot-swap replacement, and check the status LED after insertion before the PO.
A single UCS 6248 UP power supply runs the fabric interconnect, and two power supplies provide redundancy. Order a second UCS-PSU-6248UP-AC only for an AC chassis, feed each power supply from a separate source, and keep N10-S1BLKP= in an empty power bay.
UCS 6296 UP fabric interconnects
UCS-PSU-6248UP-AC fits UCS 6248 UP only. UCS 6296 UP uses UCS-PSU-6296UP-AC for AC power in its own power bay family.
-48V DC sites
UCS-PSU-6248UP-AC is an AC unit for 90-264V AC feeds. -48V DC UCS 6248 UP sites use UCS-PSU-6248UP-DC instead.
200-380V DC feeds
UCS-PSU-6248UP-AC does not take 200-380V DC input. UCS 6248 UP high-voltage DC sites use UCS-PSU-6248-HVDC in the same host.

UCS-PSU-6248UP-AC is the UCS 6248UP Power Supply/100-240VAC. The base PID is used in configured systems, and the spare form is UCS-PSU-6248UP-AC=. The AC suffix marks the 90-264V AC internal module for the UCS 6248 UP fabric interconnect. It occupies a front power bay.
UCS-PSU-6248UP-AC fits the UCS 6248 UP fabric interconnect. It does not fit UCS 6296 UP; that chassis uses UCS-PSU-6296UP-AC for AC power. A UCS 6248 UP running -48V DC uses UCS-PSU-6248UP-DC instead, and high-voltage DC sites use UCS-PSU-6248-HVDC.
A UCS 6248 UP uses UCS-PSU-6248UP-AC for 90-264V AC, UCS-PSU-6248UP-DC for -40 to -72V DC, or UCS-PSU-6248-HVDC for high-voltage DC. The AC unit is the 750W hot-swappable power supply for standard AC feeds. A UCS 6296 UP uses a different power supply family.
UCS-PSU-6248UP-AC is rated for 750W maximum output at 12V DC. It takes 90-264V AC at 50 to 60 Hz and dissipates 2497 BTU/hr at 600W. It runs in a UCS 6248 UP chassis rated for 0°C to 40°C operation. The efficiency figure is 87 to 92% at 50 to 100% load.
Yes, UCS-PSU-6248UP-AC is hot-swappable in a UCS 6248 UP fabric interconnect. Keep the second power supply installed and operating before removing a failed module. A single supply runs the chassis, and two supplies provide redundancy across separate power sources.
UCS-PSU-6248UP-AC provides 750W maximum output, with a 390W value at 110V AC. Low-line AC circuits need a sizing check before the PO. North American installations require a 15A or 20A circuit, and 90-264V AC input is the accepted range.
UCS-PSU-6248UP-AC uses a separate AC power cord for each installed power supply. Standard cords have an IEC C13 connector at the power supply end. North America uses CAB-AC-250V/13A or CAB-N5K6A-NA, and cabinet PDU builds can use CAB-C13-C14-JMPR.
No, UCS-PSU-6248UP-AC does not fit UCS 6296 UP. UCS 6296 UP takes UCS-PSU-6296UP-AC for AC power and UCS-PSU-6296UP-DC for DC power. Order by the full chassis label, because 6248 UP and 6296 UP power bay families differ.
No, UCS-PSU-6248UP-AC does not mix with UCS-PSU-6248UP-DC in the same UCS 6248 UP chassis. Redundant UCS 6248 UP configurations use two identical power supplies, either two AC units or two DC units. Use the AC unit only with another matching AC unit.
UCS-PSU-6248UP-AC uses port-side exhaust airflow in the UCS 6248 UP. Fan modules and power supply modules must have the same airflow direction. A mixed-airflow chassis can overheat and shut down, so confirm the airflow color and label before the PO.
Yes, UCS-PSU-6248UP-AC= is the spare form of UCS-PSU-6248UP-AC. The equals suffix is an ordering form for a field replacement unit, not a different electrical rating. Use the base PID for normal ordering and match the suffix on the failed unit or quote.
The difference between UCS-PSU-6248UP-AC and UCS-PSU-6248UP-DC is input power. UCS-PSU-6248UP-AC takes 90-264V AC, while UCS-PSU-6248UP-DC takes -40 to -72V DC. AC data centers use the AC PID, and -48V DC sites use the DC PID.
The difference between UCS-PSU-6248UP-AC and UCS-PSU-6248-HVDC is input class. UCS-PSU-6248UP-AC is the 90-264V AC unit, while UCS-PSU-6248-HVDC is the 750W 200V-380V DC hot-plug unit for UCS 6248 UP. Standard AC feeds use UCS-PSU-6248UP-AC.
Cisco stopped selling UCS-PSU-6248UP-AC on 31 May 2019. Cisco service ended for UCS-PSU-6248UP-AC and the UCS 6248 UP host on 31 May 2024. UCS-PSU-6248UP-AC has no Cisco replacement PID.
ORM offers UCS-PSU-6248UP-AC as new sealed or certified refurbished. New units carry up to a 3-year extended warranty, and certified refurbished units carry up to 1 year. Cisco service ended on 31 May 2024, so ORM's warranty is the cover that applies. Returns are 30 days; terms apply.
