Host port LEDs
Figure 1–4 Host Port LEDs
The four HOST ports are used for IB or
The IB LEDs (the Infiniband LEDs) located between the host ports, when solid green, indicate that there is physical connectivity with the host; when steady amber, they indicate that the subnet manager is communicating with the host.

The DISK CHANNEL ports ( jackscrew style connectors) are for disk connections. The ten ports are labeled by data channels (ABCDEFGHPS). Flashing LEDs indicate activity.
The
The TELNET port provides remote monitoring and configuration capabilities. The ACT (Activity) LED flashes green when there is Ethernet activity. It is unlit when there is no Ethernet link. The LINK LED turns green when the link speed is 1000MB/s, amber when the link speed is 100MB/s, and is unlit when the link speed is 10 MB/s.
The LINK port is used to connect single controller units in order to form a couplet via a
The COM port is an
The Controller ID Selection Switch (labeled as 1/2) allows the user to configure the units as Unit 1 or Unit 2. Each unit has an activity LED. It is green for the selected unit. The switch is comprised of two DIP switches. The first DIP switch (indicated by the 1/2 label ) is used to select the unit configuration. Flip the switch up for Unit
