6. Reconnect all the devices, power cords, and cables that you disconnected;
then, turn on the server and all attached devices.
Connecting an external device
You can attach additional external options to the input/output (I/O) connectors on
the front and rear of your server. (See “Input/output connectors” on page 108 for
more information.)
Complete the following steps to attach an external device:
1. Review the information in “Installation guidelines” on page 45, “Handling
static-sensitive devices” on page 46, and “Safety information” on page 169.
2. Turn off the server and all attached devices.
3. Follow the instructions that come with the option to prepare it for installation and
to connect it to the server.
Cabling the server
Notes:
1. You must turn off the server before connecting any cables to or disconnecting
any cables from the server.
2. See the documentation that comes with your options for additional cabling
instructions. It might be easier for you to route cables before you install certain
options.
3. Cable identifiers are printed on the cables that come with your server and
options. Use these identifiers to connect the cables to the correct connectors.
For example, the hard disk drive cables are labeled “HDD option.”
Two cable-restraint brackets are on the rear of the tower model servers. After you
connect the cables to the selected devices, you can use these cable-restraint
brackets to manage the cable routing. Route the power cords through the
power-cord restraint bracket on the bottom. Route the remaining cables (for
example, the cables that are connected to the I/O ports) through the I/O
cable-restraint bracket on the top.
See the following illustrations for the locations of the input and output connectors on
your server.
Note: The USB 3 connector is on the front of the server.
