HP DC SAN Backbone Director Switch Hardware Reference Guide

At 120 VAC, four power supplies are required when using the FR4-18i blade.
◦ Two redundant WWN cards on the non-port side, to maintain chassis-specific information
such as WWNs, IP addresses, and summary status information for each Director blade
and power supply through LEDs
◦ 4-Gb and 8-Gb SFP optical transceivers (4-Gb SFPs operate at 1 Gb, 2 Gb, or 4 Gb.
8-Gb SFPs operate at 2 Gb, 4 Gb, or 8 Gb.)
◦ XFP optical transceivers (10-Gb/s)
◦ 10-Gb SFP optical transceivers
• All blades are serviced from the port side of the DC SAN Director. Blowers, power supplies,
and power cables are serviced from the non-port side.
• Improved cable management using a re-designed cable management comb and chassis door.
• Constant intake and FRU temperature monitoring.
• Redundant AC primary power connections to ensure high availability. Each power supply has
its own connector. Therefore, the number of primary power connections varies from two to
four.
