Inserting a media card into the SP Switch Router
Note:
To operate properly, the 16-card SP Switch Router requires that at least two media cards be
installed. The 4-card router requires one card be installed. In both models, a face plate cover
must be installed in any unused chassis slot to maintain router cooling flows.
Media cards are actually two logic boards joined to make a single component. As shown in
Figure 1-3, the smaller board on the right is the serial interface, also called the serial daughter
card. The larger one on the left is the media board and has the network ports. Together they
comprise an SP Switch Router media card.
Figure 1-3. Media card components
The two logic boards are joined by a pair of 100-pin connectors and reinforcing plates. Even
so, this joint retains some flex and must be carefully supported, especially when inserting the
media card into the chassis.
Warning: The backplane of the SP Switch Router contains hazardous energy levels. When
replacing a media card, remove only one card at a time. Removing more than one card will
expose the operator to this energy hazard.
Warnung: An den Rückwandplatinen der SP Switch Router liegen gefährliche
Hochspannungen ab. Zum Auswechseln der Medienkarte jeweils nur eine Karte entfernen. Bei
zwei gleichzeitig entfernten Karten ist der Bediener gefährlichen Spannungen ausgesetzt.
