Connecting external devices Note: The ServeRAID-4H, -4L and -4M controllers do not support configurations that use both the internal and external connectors on the same channel concurrently. For example, you cannot use both external Channel 1 and internal Channel 1. To attach SCSI devices to an external channel connector on the ServeRAID controller: 1. Connect one end of a 68-pin very high density connector interface (VHDCI) SCSI cable to an external channel connector on the ServeRAID controller. Notes: a. See "Features and connector locations of ServeRAID-4H controller" on page 139 for the channel connector locations of the 4H controller, "Features and connector locations of ServeRAID-4L controller" on page 141 for the channel connector locations of the 4L controller, and "Features and connector locations of ServeRAID-4M controller" on page 143 for the channel connector locations of the 4M controller. b. The following illustration depicts the ServeRAID-4H controller. The ServeRAID-4L and -4M controllers will have a slightly different appearance. Figure 6. Connecting a ServeRAID-4H controller external channel connector 2. Connect the other end of the SCSI cable to the external SCSI device. 150 Hardware Maintenance Manual: Netfinity 7600 - Type 8665 Models 1RY, 2RY
