Connecting to the Network
Step 3 Connect the asynchronous breakout cable to one of the 68-pin ports, and then use
the RJ-45-to-DB-25 adapters to connect the breakout cable and your
asynchronous devices. (See Figure 3-12.)
For additional instructions on connecting asynchronous devices to the breakout
cable, refer to the appendix “Cable Specifications.”
Figure 3-12 Connecting Asynchronous Serial Cables
Caution
Make sure that the 68-pin connector on the breakout cable is securely connected
to the access server. A short could occur which might damage the access server if the
connection is disconnected.
Step 4 Using an M 3.5 thread-forming screw (not included), attach a ground wire to the
protective grounding terminal on the rear panel of the chassis, as required by your
installation.
Step 5 Connect the power cable between the access server and the AC source.
