Setting Up and Testing the MAX Hardware
Connecting to input power
MAX 4000 Series Hardware Installation Guide Preliminary November 4, 1998 2-7
Connecting to input power
Your power sources can be ac or dc, or a combination of both. You plug the ac source into an
outlet. (A dc source receives its power from either an ac outlet or a battery). If your unit uses ac
power, attach the power cable to the connector at the back of the unit.
(For power requirements, see Appendix B, “MAX Technical Specifications.”)
Figure 2-7. DC power source
As shown in Figure 2-7, the power source on the MAX 6000 or the Redundant MAX 6000 has
a terminal block with two separate input sources. (For an expanded view, see Figure 1-3.) The
input power is identical for both terminal columns. Connect to two different sources if you
want source redundancy. (If one source dies, the other backs up the power and the MAX unit
sees no interruption in functioning.) Following are descriptions of the terminal block
connectors:
Connecting to the LAN
To connect the MAX to the LAN, connect your Ethernet LAN cable to the Ethernet interface
on the MAX. The MAX 6000 has a 10/100Base-T Ethernet port. You will need an adapter if
you have a different type of Ethernet LAN.
