C9400-PWR-2100AC Description

The C9400-PWR-2100AC is a Cisco Catalyst 9400 Series Platinum-rated 2100W AC power supply for the C9404R, C9407R and C9410R modular chassis. The module outputs 950W at 100-120 VAC and 2112W at 200-240 VAC, drawing 10.4 A through an IEC60320/C19 appliance connector, with 55 VDC output capacity of 940W at 115 VAC and 2102W at 230 VAC. Installed supplies must share one capacity in N+1 or combined mode, so the module does not mix with 3200W supplies in those modes.

Application Scenarios

Mid-Power Chassis In A Server Room

In a server-room closet fed from 200-240 VAC circuits, the module supplies up to 2112W to a Catalyst 9400 chassis whose line cards and supervisor draw less than the 3200W class.

Redundant Power In A Wiring Closet

A closet on 100-120 VAC feeds can run several modules in N+1 redundant mode, with each module contributing 940W at 55 VDC toward the chassis budget.

C9400-PWR-2100AC is the smallest AC supply in this group, delivering 950W on 100-120 VAC and 2112W on 200-240 VAC, against 1570W and 3200W for C9400-PWR-3200AC and C9400-PWR-3200ACT, and drawing 10.4 A instead of 16 A. Racks that need 3200W of output at high-line input move to C9400-PWR-3200AC, which has the same 7 CFM minimum airflow, or to C9400-PWR-3200ACT, the Titanium-rated module with a 19.87 CFM minimum airflow. Sites fed from a DC plant need C9400-PWR-3200DC, which takes -40 to -72 VDC on DC input terminals, while all three AC modules use an IEC60320/C19 appliance connector.

PoE Power Planning

Planning Item

Cisco-Confirmed Value

Procurement Impact

Low-line AC output

940W at 55 VDC plus 10W standby output at 115 VAC

Sets the lower chassis power budget when the site feed is 100-120 VAC

High-line AC output

2102W at 55 VDC plus 10W standby output at 230 VAC

Supports the higher 2112W total output class for 200-240 VAC racks

N+1 redundant mode formula

2102W x (N-1) plus 10W standby at 230 VAC; 940W x (N-1) plus 10W standby at 115 VAC

Determines how many supplies remain available after reserving one module for redundancy

Combined mode formula

2102W x N plus 10W standby at 230 VAC; 940W x N plus 10W standby at 115 VAC

Shows the combined power pool when the design is not reserving an equivalent standby module

Power budget validation

Cisco directs users to calculate or estimate system power budget and PoE requirements with Cisco Power Calculator

Prevents PSU quantity from being approved without checking supervisors, line cards, and PoE load

Ordering Checklist

  • Catalyst 9400 chassis: Use a C9404R, C9407R or C9410R, which support 3200W AC, 2100W AC and 3200W DC power supplies. The module fits Catalyst 9400 power supply bays only, not other Catalyst families.

    When we had a question after delivery, they responded the same day. Wish the lead time was a bit shorter, but product quality made up for it.

Questions & Answers

  • How many C9400-PWR-2100AC supplies can I install in a C9404R, C9407R or C9410R chassis?

    You can install up to 4 C9400-PWR-2100AC supplies in a C9404R and up to 8 in a C9407R or C9410R. The installed supplies load-share to feed the line cards and PoE. The bay count sets the largest redundancy pool a design can use, so check it before you order spares.
  • How many 15W PoE devices can one C9400-PWR-2100AC power at 240V?

    About 140 devices at 15W, or about 35 devices at 60W, per supply at 240V. This is an arithmetic estimate from the supply output, not a limit Cisco publishes for this module, so you must confirm the chassis budget with the Cisco Power Calculator. Do not reuse the 3.2kW supply counts for this module.
  • From which IOS XE release is C9400-PWR-2100AC supported, and what is its 55 V current at 240V?

    C9400-PWR-2100AC is supported from IOS XE 16.8.1. On a 240V feed it delivers 38.21 A at 55 V, which sets the backplane current the chassis can draw. Check the supervisor release before you install the module.
  • What does C9400-PWR-2100AC weigh when I plan the chassis bay load?

    C9400-PWR-2100AC weighs 5.0 lb (2.3 kg), per the Catalyst 9400 hardware installation guide. One person can lift a single module, so a failed supply can be hot-swapped from the chassis front without lifting gear, which keeps the maintenance window short.
