Brocade DCX 8510-4 Backbone Hardware Reference Manual 9
53-1002177-06
Serviceability
1
• Dual control processors that enable hot, nondisruptive fast firmware upgrades.
• One serial port and two Ethernet ports (on each control processor) for management and for
service. Offline control processor diagnostics and remote diagnostics simplify troubleshooting.
The standby control processor monitors diagnostics to ensure the system is operational should
a failover be necessary.
• Bus monitoring and control of blades and other field-replaceable units (FRUs).
Serviceability
The Brocade DCX 8510-4 provides the following features to enhance and ensure serviceability:
• Modular design with hot-swappable components.
• Flash memory that stores two firmware images per control processor.
• USB port on control processor blades for most tasks that formerly required an FTP/SCP server,
including software and firmware upgrades.
• Nonvolatile random-access memory (NVRAM), containing the OEM serial number, Brocade
serial number, revision information, and part number information.
• Background health-check daemon.
• Memory scrubber, self test, and bus ping to determine if a bus is not functioning.
• RASlog messages.
• SMI-S compliant.
• Hardware and software watchdog timers.
• Status LEDs.
• Predictive diagnostics analysis through Fabric Watch.
• SNMP (including version 3) integration with higher-layer managers.
• Cable management using vertical finger assemblies to accommodate the horizontal
orientation of the blades.
Software features
The Fabric OS allows any Fibre Channel-compliant device to attach to the switches as long as it
conforms to the device login, name service, and related Fibre Channel standards. Each operating
environment requires that a Fibre Channel host bus adapter (HBA) be available with a
standards-compliant driver for correct interface to the fabric.
Fabric OS consists of a set of embedded applications running on top of an embedded Linux
operating system kernel. Some of these applications include:
• Name server
• Alias server
• Zone server
• Simple Network Management Protocol (SNMP) agent
• SMI-S compliant API
• Syslog auditing
