Which Catalyst 9600 chassis accept C9600-PWR-2KWDC?

C9600-PWR-2KWDC installs in the Catalyst 9606R chassis, which has four power supply bays and needs a minimum of two supplies. It fits only the C9606R power supply bays, and no other Catalyst 9600 host is listed in the datasheet.

Can C9600-PWR-2KWDC be mixed with AC modules in one C9606R?

Yes, but only when every module has equal wattage and the AC input is 220V. The rule applies in combined mode and in N+1 redundant mode, where one supply is reserved for redundancy.

Can C9600-PWR-2KWDC share a C9606R with AC modules on 110V feeds?

No. Mixing AC and DC modules requires the AC input to be 220V, and AC supplies cannot mix 110V and 220V inputs in the same chassis. A site with only 110V AC feeds cannot install AC modules next to C9600-PWR-2KWDC, so wire the AC side for 220V first.

How much does each added C9600-PWR-2KWDC contribute in Combined mode?

Each additional C9600-PWR-2KWDC adds about 90 percent of its capacity in Combined mode, which is the default. In N+1 mode one module is held as spare, so the loss of one DC module is tolerated. Choose the mode before you size the PoE budget for the chassis.

Does C9600-PWR-2KWDC have its own on/off switch in the C9606R?

Yes, each power supply has its own on/off switch. The Catalyst 9606R has four power supply slots, and Combined is the default redundancy mode. Switch the module off before you remove it, so the chassis can rebalance the load across the remaining modules without a surprise.

What DC hold-up time does C9600-PWR-2KWDC provide?

C9600-PWR-2KWDC provides 5 ms of DC output hold-up, per Table 4 of the Catalyst 9600 datasheet. Check that figure against the DC plant switchover time and the cable run before you approve the design, because a longer interruption drops the module output.

C9600-PWR-2KWDC Description

The C9600-PWR-2KWDC is a Cisco Catalyst 9600 Series 2000W DC power supply module for the Catalyst 9606R chassis. The module takes -40 to -72 VDC input at up to 60A per input, delivers 2000W of 12V output at 167A and cools front to rear. DC and AC modules can share a chassis only when every module has the same wattage and the AC input is 220V.

Application Scenarios

DC-Fed Equipment Room

In a facility with a DC power plant in the -40 to -72 VDC range, the module powers a Catalyst 9606R from DC input and carries a 70A-rated cord.

N+1 DC Redundancy

A Catalyst 9606R with two or more of these modules can run in N+1 redundant mode, with one module held in reserve while the others carry the chassis load.

C9600-PWR-2KWDC is the only DC module in this group, taking -40 to -72 VDC at up to 60A per input and delivering 2000W, while C9600-PWR-2KWAC and C9600-PWR-3KWAC are AC modules for 90 to 140 VAC or 180 to 264 VAC feeds. A site on AC power orders C9600-PWR-2KWAC for 2000W at 180 to 264 VAC, or C9600-PWR-3KWAC when each module must supply 3000W. AC and DC modules can share a chassis only when the AC input is 220V and every module has the same wattage, which rules out C9600-PWR-3KWAC beside C9600-PWR-2KWDC.

Ordering Checklist

Catalyst 9600 hosts: Install the module in a Catalyst 9600 Series C9606R chassis, which supports 3000W AC, 2000W AC and 2000W DC power supplies. It fits only the C9606R power-supply bays, and no other Catalyst 9600 host is listed in the datasheet.

We’re protective of who we trust with our procurement. Layer23 made the list. Shipping took a couple extra days, but product itself is perfect.
