C9400-PWR-2100AC is the Cisco Catalyst 9400 Series Platinum-rated 2100W AC power supply. It powers the C9404R, C9407R and C9410R chassis and carries integrated PoE. The spare number is C9400-PWR-2100AC=.
The input range is 100 to 240 VAC (plus or minus 10 percent over the full range) at a rated input current of 10.4 A at both 100 VAC and 200 VAC. Data output is 55 V at 38.21 A on the 230 VAC range or 17.09 A on the 115 VAC range, plus a 3.3 V standby output at 3.0 A. Heat dissipation is 460 BTU/hr per supply, and holdup time is 20 ms.
Output power in N+N redundant mode is (2102 W x N)/2 + 10 W standby on the 230 VAC range and (940 W x N)/2 + 10 W on the 115 VAC range, with N the number of power supplies. N+1 mode is (2102 W x (N-1)) + 10 W on 230 VAC and (940 W x (N-1)) + 10 W on 115 VAC. In combined mode the total is (2102 W x N) + 10 W on 230 VAC and (940 W x N) + 10 W on 115 VAC.
Each supply is hot swappable and has an MTBF of 300,000 hours. Status LEDs indicate output fail (red), input okay (green) and ID (blue). The minimum software is Cisco IOS XE 16.8.1.
The larger C9400-PWR-3200AC is the 3200 W AC supply for the same chassis, with 16 A of rated input current at 100 VAC and 200 VAC.
