Installation Requirements
- Ensure unobstructed chassis airflow; a minimum of 10 CFM and 490 LFM per slot is recommended.
- Connect front-panel RJ-45 serial cables correctly.
Usage Precautions
- In high EMI environments, add ferrite core filters to interfaces if serial data packet loss occurs.
- Do not use alcohol-based solvents for cleaning; use a mixture of isopropyl alcohol and deionized water.
