!Verify that the access lamp on the diskette drive is unlit before turning off the server or ejecting the floppy disk. Turning off the server or ejecting the floppy disk while the access lamp is lit may damage data being stored on the floppy disk.

!After turning off the server, wait at least 40 seconds before turning it on again. Cycling the power immediately may cause malfunction or failures of the server.

!Before relocating the server, turn off the power and unplug the power cord from the outlet. Moving the server when it is powered may cause malfunction or failures of the server.

!Some software includes a command to eject the CD-ROM tray or a media in a device mounted in the 5.25-inch device bay. Make sure that the front door of the tower-based cabinet is open before running the command.

Running this command with the front door closed may cause the CD- ROM tray or the media to hit against the front door, resulting in a possible failure of the CD-ROM.

!Clean the server regularly. Regular cleaning prevents failures of the server and its components.

!Lightning may cause a momentary voltage drop. To prevent this problem, an uninterruptible power supply unit is recommended.

!Only use options qualified for the server. A non-qualified option may be mounted or connected to the server, but it may fail to operate normally or even cause failures. These types of failures are not covered under warranty.

Opening the Front Door of the Tower Cabinet

You must open the front door of the tower cabinet to turn the server power on or off, place the server in sleep mode, mount or dismount a floppy disk, mount or dismount a hard disk drive, or mount or dismount 5 1/4-inch removable media devices.

Note: The standard CD-ROM drive and some options for the 5 1/4-inch devices such as a CD-ROM drive have a function to eject a tray or media using a software command. Before issuing a software command to eject a tray or media, confirm that the front door is open. If the command is executed while the front door is closed a tray or media may run into the front door resulting in an error or may cause the unit to fail.
