C9K-PWR-650WAC-R Description

The C9K-PWR-650WAC-R is a Cisco Catalyst 9500 Series 650W AC power supply module for High Performance switches in wiring rooms and data center racks. The module accepts 90 to 264 VAC at 47 to 63 Hz, draws up to 6.8A at 115 VAC and delivers 12V main at 54A plus 12V standby at 3A at 94 percent typical efficiency. The module is listed for the C9500-32QC, C9500-48Y4C and C9500-24Y4C, and the 1600W supplies of the C9500-32C do not fit these switches.

Not published

C9K-PWR-650WAC-R and C9K-PWR-650WACL-R are both 650W AC supplies with 90 to 264 VAC input and the same three Catalyst 9500 hosts, but C9K-PWR-650WAC-R is rated for 4KV CM and 2KV DM surge, at least 20 ms of AC line hold-up at 90 percent load and 130 percent over-power protection, against 2.5KV CM, 1KV DM, 12 ms at 100 percent load and 140 percent for C9K-PWR-650WACL-R. Where Cisco’s European dual-supply rule applies, the chassis needs C9K-PWR-650WACL-R in both bays. A site with a -48 VDC feed, or one that wants 930W, moves to C9K-PWR-930WDC-R, which takes -40 to -72 VDC and up to 23A at -48 VDC.

Ordering Checklist

  • Catalyst 9500 hosts: Order for C9500-32QC, C9500-48Y4C and C9500-24Y4C. This 650W AC supply is listed for these three High Performance models only.

    Five-star experience all around. Would recommend without hesitation. Took a little longer to clear customs than expected, otherwise excellent.

Questions & Answers

  • Which PID orders the redundant second C9K-PWR-650WAC-R?

    Order C9K-PWR-650WAC-R/2 for the redundant second supply. Cisco uses the /2 suffix for the second power supply, per the Catalyst 9500 ordering guide. Use that PID when a Catalyst 9500 High Performance switch needs two supplies and you want the second unit on the same bill of materials.
  • Is a second C9K-PWR-650WAC-R preselected when I configure a Catalyst 9500?

    Yes, the ordering guide preselects the second power supply, and the switch includes a single AC supply by default. To remove the second supply you must select C9500-SPS-NONE explicitly. Check the bill of materials for that line before you approve a single-supply build.
  • Does a Catalyst 9500 using C9K-PWR-650WAC-R accept PWR-C4-950WAC-R or PWR-C4-950WDC-R?

    No, PWR-C4-950WAC-R and PWR-C4-950WDC-R are not supported in the High Performance models listed for C9K-PWR-650WAC-R. Those 950W supplies belong to a different Catalyst 9500 host group. The Table 14 support matrix lists the 1600W AC and DC supplies as unsupported too.
  • What heat load should I plan for a C9500-24Y4C-A or C9500-24Y4C-E fitted with C9K-PWR-650WAC-R?

    A C9500-24Y4C-A or C9500-24Y4C-E fitted with C9K-PWR-650WAC-R is rated at 1,454 BTU/hr in Table 13 of the Catalyst 9500 datasheet. Use that value for the rack cooling load, because the figure depends on the host model.
