Host Port LEDs
The four 
HOST
 ports are used for IB or FC-8 host connections. You can connect your host servers IB 
HCA port(s) or FC HCA port(s)directly to these ports. Additionally, you can connect these ports to your 
IB or FC switches and hubs. 
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.
On FC-8 models, the 
FC LEDs
 are located next to each FC host port. There are 3 LEDs for each host 
port, which indicate if the connection is running at 8 GB (left LED), 4 GB (middle LED), or 2 GB (right 
LED). The respective LED will be a solid green to show that there is a physical connection. If the 
respective LED is flashing, this indicates data transfer. If the connector is taken from the host port, all 3 
LEDs for that port will flash.
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 
RS-232
 connector provides local system monitoring and configuration capabilities and uses a 
standard DB-9 null modem female-to-male cable. 
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/samber 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 cross-over 
Ethernet cable. The  
ACT
 (Activity) LED flashes green when there is Ethernet activity. The LED 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 
COM
 port is an RS-232 Interface that uses an RJ-45 cable and connects controller units. The 
COM
 
port has two(2) LEDs associated with it:  
HDD ACT
 (Activity) and 
 LINK ACT.
 
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 1---down for Unit 2.  When two controller controllers are 
paired together to form a couplet,  one controller must be configured as unit 1 and its partner must be 
configured as unit 2.
