C9K-PWR-CAB-AC-IS=: What Power Cable Is Needed for Catalyst 9000 Switches? Compatibility, Safety, and Availability

Defining the C9K-PWR-CAB-AC-IS=

The ​​C9K-PWR-CAB-AC-IS=​​ is a ​​regionalized AC power cable​​ designed for Cisco Catalyst 9400 and 9500 Series switches. It connects the switch’s power supply unit (PSU) to local AC outlets, ensuring compliance with ​​safety and electrical standards​​ in specific geographic markets.

Technical Specifications and Regional Variations

• ​​Voltage Rating​​: 100–240V AC, 10A, compatible with global power grids.
• ​​Plug Type​​: ​​Type IS (Israeli Standard SI 32)​​ 3-pin plug for use in Israel and Palestine.
• ​​Cable Length​​: 2 meters (6.56 ft) with shielded connectors for EMI reduction.
• ​​Certifications​​: UL/CSA/IEC/CE safety compliance and RoHS environmental standards.

Why Use Cisco’s OEM Power Cables?

Third-party cables may lack ​​proper shielding or certifications​​, risking:

• ​​Electrical Hazards​​: Overheating due to undersized conductors.
• ​​Compliance Violations​​: Fines for using non-certified cables in regulated industries.
• ​​Voided Warranties​​: Cisco may deny support if non-OEM cables damage the PSU.

Installation Guidelines

1. ​​Verify Voltage Compatibility​​: Ensure local AC voltage matches the PSU’s input range (e.g., C9K-PWR-3KWAC-R=).
2. ​​Secure Connection​​: Plug the C9K-PWR-CAB-AC-IS= into the PSU’s C19 inlet and tighten the retention clip.
3. ​​Grounding Check​​: Confirm the outlet’s grounding pin is functional to prevent electrostatic damage.

Use Cases Requiring Regional Cables

1. ​​Global Deployments​​: Data centers or offices in Israel needing ​​localized power connectors​​.
2. ​​High-EMI Environments​​: Industrial sites where shielded cables prevent signal interference.
3. ​​Regulated Industries​​: Healthcare or finance sectors requiring strict compliance with safety standards.

Where to Source the C9K-PWR-CAB-AC-IS=

While Cisco.com lists regional cable variants, suppliers like “itmall.sale” offer ​​cost-effective surplus or refurbished cables​​ with verified certifications. Prioritize sellers who provide authenticity guarantees and batch testing reports.

The Hidden Risks of Overlooking Power Cables

The C9K-PWR-CAB-AC-IS= exemplifies how ​​seemingly mundane components​​ can impact network reliability. While enterprises often prioritize switches and licenses, subpar cables remain a silent threat. For multinational deployments, investing in region-specific accessories isn’t optional—it’s foundational to operational integrity and safety.
