N20-PAC5-2500W is a 2500W AC internal power supply for UCS 5108 blade server chassis, with hot-swap service in redundant chassis power modes. The module fits the UCS 5108 AC chassis and shares the front power supply bays with the other 5108 supply options. A Cisco UCS 5108 power supply bay can take up to four hot-swappable units. The chassis supports nonredundant, N+1 redundant and N+N grid redundant power. Grid redundancy uses slots 1 and 2 for grid 1 and slots 3 and 4 for grid 2. Before the PO, confirm the AC chassis version, the fabric interconnect and the bay count. UCSB-PSU-2500ACPL is the Platinum AC sibling for the same chassis bay.

2500W output at 200 to 240V AC sets the circuit class for this UCS 5108 2500W power supply. 180 to 264V AC input range and 47 to 63 Hz frequency require a 200 to 240V rack feed. 15.5A at 200V AC sizes the branch circuit. 12V DC output feeds the chassis power distribution. 12 ms hold-up time gives the power train its ride-through figure. 8525 BTU/hr output belongs in the rack thermal plan. Gold efficiency separates N20-PAC5-2500W from Platinum 5108 AC supplies. IEC320 C20 input and a 16A, 250V AC C19 cord match the chassis PDU. 10°C to 35°C operating temperature follows the UCS 5108 rack limit. A 3.2 kg module changes service handling more than rack load.
N20-PAC5-2500W ships as new sealed or certified refurbished for UCS 5108 AC chassis sparing. Certified refurbished units are inspected and bench-tested in a compatible host or on a load tester; hot insertion and removal are verified in a live host. Order the matching AC UCS 5108 bay module and a 16A, 250V C19 cord for each populated bay. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and returns are 30 days on every condition; terms apply. UK, EU, US and MEA stock support RMA with advance replacement, PO accepted and Net-30 for government.

A failed UCS 5108 AC chassis bay needs the same power family and the same input class. Match N20-PAC5-2500W to a 200 to 240V AC UCS 5108 chassis and keep the empty bay covered with N20-CBLKP if the replacement is not installed immediately.
A grid-redundant UCS 5108 build splits power supplies across two feeds. Place equal counts on both grids, with slots 1 and 2 on grid 1 and slots 3 and 4 on grid 2. For two redundant supplies, specify slots 1 and 3 before the PO.
A UCS 5108 sparing pool needs the base module and the spare ordering form. Keep N20-PAC5-2500W for installed modules and N20-PAC5-2500W= for spare replacement stock. Confirm 200 to 240V AC rack power and a C19 cord for each spare.
UCS 6324 Fabric Interconnect builds
UCS 6324 configurations take UCSB-PSU-2500ACDV or UCSB-PSU-2500DC48 only. Use UCSB-PSU-2500ACDV for a dual-voltage AC UCS 5108 build.
100 to 120V AC circuits
N20-PAC5-2500W is a 200 to 240V AC supply. Use UCSB-PSU-2500ACDV where the UCS 5108 chassis must run from low-line AC.
-48V DC sites
N20-PAC5-2500W is an AC power supply for the AC chassis version. Use UCSB-PSU-2500DC48 for -48V DC UCS 5108 power.

N20-PAC5-2500W is the 2500W AC power supply unit for UCS 5108. The base PID is the installed ordering form, and N20-PAC5-2500W= is the spare form. The supply is a Gold AC hot-swap module for UCS 5108 AC chassis power bays.
N20-PAC5-2500W fits the UCS 5108 AC blade server chassis. The supply does not fit UCS 6324 Fabric Interconnect configurations; those builds take UCSB-PSU-2500ACDV or UCSB-PSU-2500DC48. Before the PO, confirm the chassis version and fabric interconnect on the system label.
A UCS 5108 uses N20-PAC5-2500W, UCSB-PSU-2500ACPL or UCSB-PSU-2500DC48 in standard AC or DC chassis versions. UCS 6324 configurations use UCSB-PSU-2500ACDV or UCSB-PSU-2500DC48 only. The correct choice follows the chassis power distribution system and input feed.
N20-PAC5-2500W is rated for 2500W output at 200 to 240V AC. The supply takes 180 to 264V AC at 47 to 63 Hz, draws 15.5A at 200V AC and outputs 12V DC. Hold-up time is 12 ms, and weight is 3.2 kg.
Yes, N20-PAC5-2500W is hot-swappable in a UCS 5108 chassis. A chassis with more than two sufficient supplies can keep servers operating while one unit is removed. A one-supply chassis shuts down when that supply is removed.
No, N20-PAC5-2500W is a 200 to 240V AC supply with a 180 to 264V AC range. The 15.5A input figure is rated at 200V AC. Use UCSB-PSU-2500ACDV for UCS 5108 low-line AC requirements.
N20-PAC5-2500W uses the UCS 5108 AC PDU cord set. The chassis PDU uses an IEC320 C20 socket, and the cord uses an IEC 60320 C19 connector at the chassis end. CAB-AC-2500W-US1 is the non-locking North America 200 to 240V cord.
No, AC and DC UCS 5108 power supplies must not be mixed in the same chassis. The power supplies are keyed to the matching power distribution system. Use N20-PAC5-2500W in the AC chassis and UCSB-PSU-2500DC48 in the DC chassis.
N20-PAC5-2500W is the Gold AC supply, and UCSB-PSU-2500ACPL is the Platinum AC supply for UCS 5108. Both fit the same chassis bay. Choose N20-PAC5-2500W for like-for-like Gold replacement and UCSB-PSU-2500ACPL for Platinum AC sparing.
N20-PAC5-2500W is an AC supply, and UCSB-PSU-2500DC48 is the -48V DC supply for UCS 5108. The AC and DC modules match different chassis power distribution systems. Choose the PID that matches the feed and the chassis power version.
Cisco stopped selling N20-PAC5-2500W on April 10, 2026. The UCS 5108 chassis stopped selling on December 31, 2025, and service for the UCS 5108 chassis ends on December 31, 2030. No migration PID replaces this supply.
ORM Systems offers N20-PAC5-2500W 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. Certified refurbished units are inspected and bench-tested, with 30-day returns on every condition; terms apply.
