Channel 2 Expansion
The MegaRAID controller has three channels available for cabinet connection. Two of the
channels (0 and 1) are available on the back of the controller. The third channel (2) is
accessible via the Channel 2 port to the left of the I/O panel. If the Channel 2 access cable is
not installed in the base unit, you must install the cable to use Channel 2 of the controller.
To determine if the cable is installed, see if the Channel 2 port has a connector or a metal
plate over the port. If a connector is present, the cable is installed. If the metal plate is
present, install the access cable if it is included with the disk array cabinet.
NOTE
The disk array cabinet attached to the Channel 2 port must be a single-channel cabinet. The
following instructions describe how to install the Channel 2 access cables in the base unit.
These steps assume the required secondary controllers have been installed and the unit is
open.
To install the Channel 2 access cable:
1. Connect the Channel 2 access cables to the Channel 2 connector of the secondary
MegaRAID controllers.
2. Connect the other end of the access cables to the Channel 2 ports as follows. See the
following figure.
−
Attach the cable from the controller in PCI slot 5 to the top Channel 2 port.
−
Attach the cable from the controller in PCI slot 6 to the middle Channel 2 port.
−
Attach the cable from the controller in PCI slot 7 to the lower Channel 2 port.
