Radio Frequency Testing

Network switches deployed in data center, enterprise, and carrier infrastructure in Canada must comply with ISED (Innovation, Science and Economic Development Canada) regulations for both unintentional emissions (ICES-003) and, for managed switches with wireless management interfaces, intentional radiator requirements (RSS-247 for Wi-Fi/BT). For switch manufacturers accustomed to FCC Part 15B (US) and CE-EMC (EU), the ISED compliance pathway introduces a unique structure: a 1-2 year ISED Interim certification that transitions to permanent ISED Terminal Equipment registration, combined with Canada-specific labeling (French/English bilingual) and a mandatory ISED Company Number (CN) registration. This article maps the ISED compliance pathway for enterprise switches and the data-reuse opportunities from existing FCC and CE certifications.

ISED Regulatory Framework for Switches — ICES-003 and RSS-247

Switches fall under two ISED regulatory documents:

ICES-003 Issue 7 — Unintentional Emissions　Canada's equivalent of FCC Part 15B for Information Technology Equipment (ITE). Radiated emission limits for Class A (industrial/commercial): 30-88 MHz = 90 μV/m @ 10 m, 88-216 MHz = 150 μV/m, 216-960 MHz = 210 μV/m, >960 MHz = 300 μV/m. For Class B (residential), the limits are approximately 10 dB stricter across all bands. Switches deployed in data centers and enterprise wiring closets default to Class A, but the product's marketing language determines classification — if the switch is sold through retail channels, ISED may require Class B.

RSS-247 — Intentional Radiators (Wi-Fi/BT)　Applicable if the switch has an embedded wireless management module (common in enterprise AP-managed switches). RSS-247 maps closely to FCC Part 15C §15.247 for 2.4 GHz DTS operation. Test data generated per ANSI C63.10 is accepted by ISED without re-measurement — the key ISED-specific item is the French-language compliance statement on the label and in the user manual.

ISED Certification Process — Company Number + Interim to Permanent Path

1. ①Register ISED Company Number (CN) — Before any product certification, the manufacturer or Canadian representative must register with ISED to obtain a unique Company Number. This is a one-time registration per legal entity.
2. ②Submit test report to an ISED-recognized CB (Certification Body) — FCC Part 15B/15C test reports from an ISED-recognized lab are accepted through the US-Canada MRA. The CB reviews and issues the ISED certificate (IC: XXXXX-YYYYYYYY).
3. ③Labeling: The switch must display "IC: XXXXX-YYYYYYYY" on the product label, along with the required French/English compliance statement. The statement must read in both languages: "This device complies with ISED's licence-exempt RSS(s)" / "Le présent appareil est conforme aux CNR d'ISDE Canada..."

For switches that already hold FCC certification, the ISED process is primarily a document review rather than re-testing — the FCC test data is accepted wholesale, reducing the incremental effort to ISED filing and labelling compliance. switch FCC ISED certification data sharing pathway documentation.

Switch-Specific EMC Considerations — High-Density Port Emissions

A 24/48-port enterprise switch presents unique EMC challenges under ICES-003: the 24 or 48 Ethernet ports, when active simultaneously, create a composite emission field from the combined cable radiation. ISED's EMC test configuration requires all ports to be connected and active (per ICES-003 §6.2), with representative traffic (typically 30% line rate minimum) flowing through each port. The switch's internal power supply (usually a hot-swappable PSU module) must also be certified — either as a UL/CSA Recognized component or with its own ISED certification.
