Dell PowerEdge 1655MC - Manual (Page 5)

Table 1 -1 provides information about the status indicators.
Table 1-1. Server Module Status Features
Using the USB Diskette or USB CD Drives
Each server module has a USB port on the front of the server module, which allows you to connect a USB diskette drive or USB CD drive. The drives are used
to configure the server module.
1. Attach the drive shelf to the front of the system (see Figure 1 -3 ).
Ensure that the drive shelf rests on the center handles of the server modules. If it is placed in the center, you can attach one of the USB drives to any
server module.

other USB device.
