Dual 7-segment display board
The dual 7-segment display board displays the host controller-assigned port and box ID number for the
MSA60 to which it is connected.
The host controller has two external ports. Each port supports up to two MSA60 enclosures, for a total of up to four MSA60 enclosures per host controller. See "Choosing a configuration (on page 20 )."
When connected to multiple MSA60 enclosures, the host controller assigns the box ID number according to connection order.
The following table shows MSA60 enclosures and their associated port and box ID assignments:
Storage enclosure Port Box ID
MSA60 1
MSA60 2
MSA60 3
MSA60 4
