Brocade Communications Systems DCX Backbone Hardware Installation Manual page 16

Hardware components
• Two slots for control processor blades (CP8):
– A single active CP8 blade can control all 512 ports in the chassis.
– The standby CP8 blade assumes control of the Brocade DCX if the active CP fails.
NOTE
Device control processors and management modules contain batteries for RTC/NVRAM backup. Do not attempt to
replace these batteries. Dispose of hardware components containing these batteries as required by local ordinances
and regulations.
• Two slots for core switch blades (CR8):
– CR8 blade interconnects all port blades.
– Two inter-chassis link (ICL) connectors per blade to connect to another chassis.
– Both CR8 blades are active.
• Modular hot-swappable port blades:
– 16-port, 8-Gbps blades (FC8-16)
– 32-port, 8-Gbps blades (FC8-32)
– 48-port, 8-Gbps blades (FC8-48)
– 64-port, 8-Gbps blades (FC8-64)
• Modular hot-swappable application blades:
– FX8-24: 24-port (12 FC, 10 GbE, 2 10GbE) FCIP extension blade enabling long distance communication over existing
IP infrastructure.
– FCOE10-24: 24-port (24 10GbE) CEE-based FCoE blade enabling enhanced connectivity using existing Ethernet
infrastructure. This blade cannot be used in the same chassis as the high density port blade FC8-64 or any of the other
application blades (FX8-24 or FS8-18).
• Modular hot-swappable encryption blades:
– FS8-18: 16-port, up to 4 blades per chassis, supporting data cryptographic (encryption/decryption) and data-
compression capabilities.
• Modular hot-swappable field-replaceable units (FRUs):
– Three blower assemblies.
– Up to four power supplies (100-240 VAC auto-sensing).
› At 240 VAC: A minimum of two power supplies is required, regardless of the number of port or application blades.
240 VAC is recommended for efficiency and high availability.
› At 120 VAC: Four power supplies are required when using the FS8-18, FX8-24, or FCOE10-24 blades.
› Redundant AC primary power connections to ensure high availability. Each power supply has its own connector, so the
number of primary power connections varies from two (recommended minimum) to four (optimum efficiency and
redundancy).
– Two WWN cards.
– Small Form-factor Pluggable (SFP, SFP+, and mSFP) optical transceivers. SFP transceivers support speeds of 1, 2, and 4
Gbps. SFP+ and mSFP transceivers support speeds of 2, 4, and 8 Gbps.
– Extended Form-factor Pluggable (XFP) optical transceivers (10 Gbps).
NOTE
The 8-Gbps SFPs and mSFPs auto-negotiate at 2, 4, and 8 Gbps. The 4-Gbps SFPs auto-negotiate at 1, 2, and 4 Gbps.
• Blades that are serviced from the port side of the Brocade DCX. Blowers, power supplies, and power cables that are serviced
from the nonport side.
