Cabling and Configuration

Setting First/Second Shelf

This switch enables a shelf to be set as the “First” or “Second” shelf. In Single

shelf configurations this switch should always be set at First. In Dual shelf (daisy-

chained) configurations, one shelf must be set as First and the second shelf must

be set as Second. The switch is located at the rear of the shelf (see Figure 3-1). To

set the shelf to First, the switch should be set to “First”. To set the shelf to Sec-

ond, the switch should be set to “Second”.

Setting Single/Dual Host

This switch enables a shelf to be set up for single or dual host. A single shelf may

be either single or dual host. In dual shelf configurations both shelves can be set

to single host or dual host, but they must both be the same. The switch is located

at the rear of the shelf (see Figure 3-2). To set a shelf to single host, the switch

should be set to “1”. To set a shelf to dual host the switch should be set to “2”.
