Why Choose This Product?

• Purpose-built for EL1000 – Provides the HPE-specific mounting solution for organizations deploying an Edgeline EL1000 in a 4-post rack.
• Supports standard 19-inch rack infrastructure – Works with HPE and third-party 4-post 19-inch racks, making it suitable for established enterprise rack environments. 
• Designed around front-to-back airflow – Helps align the EL1000 installation with conventional rack cooling layouts. 
• Enables in-rack serviceability – Provides a mounting approach designed for service access while the system remains rack installed
• Clear depth requirement – The documented 34-inch mounting solution depth, including CMA, gives facilities and infrastructure teams a concrete clearance figure for rack planning. 
• Reduces configuration uncertainty – The exact HPE SKU makes it easier to identify the intended rack-mount option rather than relying on an unverified universal bracket.
• Supports structured edge deployments – Makes the EL1000 easier to incorporate into rack-based data-center, telecom, industrial, and remote-edge infrastructure.
• Procurement-friendly HPE identifier – 878576-B21 provides an exact option number for BOMs, quotations, asset records, and replacement sourcing.
