Device number

Before installing MSDL cards, determine which of the devices in the system are available. If
all 16 devices are assigned, remove one or more installed cards to replace them with MSDL
cards.
Make sure that the device number assigned to the MSDL card is not used by an installed card,
even if one is not configured. Use the MSDL planning form, at the end of this section, to assist
in configuring MSDL cards.

MSDL interfaces

Before installing the cards, select the switch settings that apply to your system, the interfaces,
and card addresses.
