4.10 Interface Cards
The NetPerformer interface cards add optional hardware interfaces to the SDM-9XXX
Series. They provide a physical interface to external devices and networks, scalable to the
needs of your application.
• The SDM-9120 can be installed with a maximum of 2 low-profile interface
cards.
• The SDM-9220 can be installed with a maximum of 2 interface cards.
• The SDM-9230 can be installed with a maximum of 3 interface cards.
The interface cards slide into slots located at the rear of the unit (see
Figure 4-2 on “Rear
View of the SDM-9230 UAC” on page 4-3). To install an interface card in the SDM-9220/
9230 chassis, follow the procedure in “Installing an Interface Card” on page 3-17.
4.10.1 SDM-9120 versus SDM-9220/9230
All three units use the same interface boards; however, the SDM-9120 has a low profile
chassis requiring only 1 Rack Unit of space. Consequently, the SDM-9120 interface cards
must also be low profile using different faceplate than the SDM-92x0. See Figure 4-9
below.
