Filler Cards
2.7 Filler Cards
If a card slot is left empty, a filler card must be installed in the slot. The filler card serves three functions:
it prevents exposure to hazardous voltages and currents inside the chassis, it eliminates electromagnetic
interference (EMI) that might disrupt other equipment, and it directs the flow of cooling air through the
chassis.
Caution Do not operate the ONS 15310-MA SDH system unless a card is plugged into each card slot.
The blank card is a printed circuit board (PCB) with a blank faceplate and two rear connectors that plug
into receptacles at the back of the slot. CTC detects when a filler card is plugged in and displays it in
node view.
Figure 2-9 shows the filler card faceplate. This card is used in ONS 15310-MA SDH traffic card slots.
Figure 2-9 Filler Card
Caution Do not attempt to install the FILLER card in a 15310E-CTX-K9 card slot (Slots 3 and 4) on the
15310-MA SDH shelf assembly. Only a CTX FILLER card should be installed in the 15310E-CTX-K9
slot.
