• Two blower assemblies.
• Two 100 to 240 VAC power supplies.
•Two WWN cards.
• Small Form-factor Pluggable (SFP and SFP+) optical
transceivers (1-, 2-, 4-, and 8-Gbps).
•Extended Form-factor Pluggable (XFP) optical transceivers
(10-Gbps).
Note: The 8-Gbps SFPs autonegotiate at 2, 4, and 8 Gbps. The 4-Gbps SFPs
autonegotiate at 1, 2, and 4 Gbps.
◆ Blades that are serviced from the port side of the ED-DCX-4S-B.
Blowers, power supplies, and power cables that are serviced from
the nonport side.
◆ World Wide Name (WWN) cards on the nonport side, with WWN
status LEDs located under the bezel.
◆ Improved cable management using two vertical cable
management fingers and a redesigned chassis door.
◆ Constant intake and FRU temperature monitoring.
◆ Redundant AC primary power connections to ensure high
availability. Each power supply has its own connector.
Port side of the ED-DCX-4S-B
Note: Airflow in the ED-DCX-4S-B is from the nonport side to the left side of
the chassis (viewed from the port side) and out the exhaust vent. If you use
the Port Side Exhaust Kit the air vents on the port side of the chassis (see
Figure 2 on page 20). The port side exhaust kit is required when mounting
the ED-DCX-4S-B in any closed side cabinet.
Figure 1 on page 19 displays a sample configuration of the port side
of the ED-DCX-4S-B.
