Arista DCS-7388-LCVR | 7388 Blank Line Card Slot Cover, Modular Switch

Q: Why do I need a blank cover for empty line card slots?
A: Blank covers are essential for maintaining proper airflow within the modular chassis. They ensure optimal cooling performance, prevent dust and debris from entering the system, and maintain the structural integrity required for EMI compliance and thermal management in high-performance data center environments.

Q: Which Arista switches is the DCS-7388-LCVR compatible with?
A: The DCS-7388-LCVR is specifically designed for Arista 7388 and 7388X5 series modular data center switches. These are 4RU high-density modular switches with 8 interface module slots supporting 100G, 200G, and 400G interfaces.

Q: Can I install this cover without shutting down my switch?
A: Yes, blank covers are typically hot-swappable components that can be installed or removed from vacant slots without powering down the chassis. However, always follow proper handling procedures to avoid disrupting adjacent active line cards.

Q: How many blank covers do I need for my 7388 chassis?
A: The number depends on your configuration. The 7388X5 chassis has 8 line card slots. You will need one DCS-7388-LCVR blank cover for each empty slot not occupied by an active line card to maintain proper airflow and thermal performance.

Q: Is this the same as the DCS-7500-LCVR or DCS-7800-LCVR?
A: No, each Arista modular switch series has its own specific blank covers. The DCS-7388-LCVR is designed exclusively for the 7388 series. Do not interchange blank covers between different switch series as they have different dimensions and mounting requirements.
