once the server is secured in the rack, you can connect the cables and power cord to its back and front panels.
follow these steps to connect cables for network connections and peripheral devices.
1 assemble the cables and devices you will connect to the server’s back panel. make certain that each cable has the proper connector and that it is designed for use in a high-capacity server. (check the documentation for each peripheral device or cable to determine that it can be used with the server.)
2 attach an identifying label to each cable you are connecting.
the labels allow you to locate a specific cable quickly and avoid errors when disconnecting cables.
3 beginning at one side of the server’s back panel, connect each cable to its respective port.
do not attach the power cord yet.
important if you use the cable-management arm, your cables must be approximately 3 feet longer than the distance between the server and its peripheral devices. this extra length may not be feasible for some cables, such as scsi cables. in this instance, you can bypass the cable-management arm with a shorter cable. but you must disconnect that cable when you open the server.

4 arrange all the cables on the back panel in the cable-management arm and secure them with the straps provided with the cable-management arm.
the cable-management arm can only be used with a four-post rack or cabinet.
if you are not using the cable-management arm, skip this procedure. it’s a good idea to group the cables and arrange them so that they don’t cause any hazard and are easy to handle should you need to detach them when opening the server.

a group the cables together loosely and “fold” them to the right side of the back panel, until they are near the short (inner) end of the cable-management arm.
b reverse the direction of the cables and lay them along the edge of the cable-management arm closest to the server’s back panel.
c attach the cables to the arm with the straps provided. wrap the cables so that the sides of facing straps do not stick to each other.
d reverse the direction of the cables again and lay them along the edge of the cablemanagement arm furthest from the back panel.
e attach the cables to the arm with the straps provided.
5 connect the power cord to the back panel.
6 attach the power cord’s retainer clip to the back panel to keep the power cord in place when you open the server.
the ends of the clip fit into the small openings at either side of the power socket. be sure that the rounded part of the clip goes under the cord, so that the cord is supported.

if more than one power cord came with your server, use the appropriate cord for the electrical service available at your location.
you can use the long power cord supplied with the server, or another cord, such as one already installed in the rack.
7 if you will be using the firewire port on the front panel of the server, connect a cable to it.
8 when all cables are in place, connect each one to its intended device.
important when connecting peripheral devices, be sure to allow adequate space at the front and back of the server for proper airflow and access to the rack for servicing.
9 after all connections are complete, plug the power cord into a power source.
with the server in the rack and the cables in place, you can prepare to set up the mac os x server software.
warning this equipment is intended to be electrically grounded. your server is equipped with a three-wire grounding plug—a plug that has a third (grounding) pin.
this plug will fit only a grounded ac outlet. this is a safety feature. if you are unable to insert the plug into the outlet because the outlet is not grounded, contact a licensed electrician to replace the outlet with a properly grounded outlet. do not defeat the purpose of the grounding plug!
because you are installing the server in a rack with other equipment, be certain that the power outlet and any other equipment, such as a power strip, used with the rack is designed to carry the electrical load of multiple devices. check the documentation for your rack for any special instructions.
