Chapter 1: Introduction
Unlike previous Fibre-to-Fibre models, I/O modules do not provide
configuration jumpers.
All drive channels come with loop switch circuits to maintain loop
integrity in the event of cable link of drive failure. The loop switch
circuits ensure loop integrity and also allow you to configure
redundant data paths for maximum protection.
Two (2) LEDs per FC port indicate each port’s connection status.
These modules are hot-swappable.
1.3 System
Monitoring
The F16F subsystem comes with a number of different monitoring methods
that provide you with continual updates on system status and individual
components. The following monitoring features are included in the
subsystem.
1.3.1 I
2
C bus
The following F16F subsystem elements are interfaced to the RAID
controller over a non-user-serviceable I
2
C bus:
PSUs
Cooling modules
Temperature sensors and presence detection circuitries
1.3.2 LED
Indicators
The following components come with LEDs to indicate the statuses of
individual components. Please refer to
Chapter 3
for more information on
System Monitoring.
LCD panel (3 LEDs)
Drive tray (2 LEDs on each tray)
RAID controller (6 controller status LEDs, 1 restore default LED,
and 2 Ethernet port status LEDs on each module)
BBU (1 LED on each module)
