The internal power supply in each module provides DC power for the MSDL
and other cards. Power consumption and heat dissipation for the MSDL is
listed in Table 153.
Installation
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

Table 154 on page 405 shows the switch positions for the DCE and the DTE
interface configurations on the MSDL card. Figure 85 on page 406 shows the
MSDL and the location of configuration switches on the MSDL. The switch
