Note On an MGX 8880, you might find that some cables do not fit into the cable m anagement system. If the
cables are too thick (for example, the T1E1 cards have thick cables), remove the fins, which are attached
with two small Phillips-head screws.
Connect the Fan Tray Power Cables to the Cisco MGX 8850 or MGX 8850/B Switch
The fan trays receive power from the backplane through fan tray power cables. To reach the backplane
D-connector, the fan power cable D-connector passes through an opening at the bottom rear of the card
cage. There are four openings for cabling: two for system power and two for fan tray power. From left
to right, the sequence of the access openings in the card cage is as follows:
1. System power (source A)
2. Fan tray power (lower fan tray)
3. System power (source B)
4. Fan tray power (upper fan tray)
Caution Do not use a power screwdriver on captive screws.
Complete the following steps to connect the fan tray power cables to the switch:
Step1 Notice that the smaller side of the backplane D-conn ector faces down, and position the smaller side of
the cable D-connector so that it also faces down. Figure 5-19 shows the connectors for the fan tray
power cable.
