CISCO C9K-PWR-930WDC-R/2 Catalyst 9500 Series Switches

C9K-PWR-930WDC-R/2 Ordering Identity

Cisco's Catalyst 9500 ordering guide lists C9K-PWR-930WDC-R/2 as the 930W DC Power Supply, Redundant option. The exact suffix matters: the guide lists C9K-PWR-930WDC-R separately as the 930W DC power-supply module, so the two product identifiers should not be substituted without checking the requested redundancy configuration.

Supported Platform Context

Cisco's Catalyst 9500 hardware guide documents the underlying C9K-PWR-930WDC-R module for C9500-32QC, C9500-48Y4C and C9500-24Y4C High Performance switches. These chassis provide two power-supply slots and support hot-swappable field-replaceable power modules. The precise bill of materials for an order should still be confirmed in Cisco Commerce Workspace or the supplier quotation.

Redundancy and Site Readiness

A redundant power configuration does not remove the need to validate both DC feeds, grounding, conductor preparation and polarity. Cisco's installation procedure requires DC power isolation before connection work and LED verification after power is applied. Confirm whether the site design uses independent DC sources and whether the existing chassis already contains a compatible module.

• Quote the full /2 SKU rather than truncating it to the single-module part number.
• Verify the target Catalyst 9500 chassis PID and installed PSU inventory.
• Confirm redundancy topology, DC feeds, grounding and conductor requirements.
• Record the ordered bill of materials instead of inferring package quantity from the suffix alone.
