Preparing a rack model Before you begin Read the documentation that comes with the rack enclosure for additional safety and operating information. The hard disk drives in the Netfinity 5000 are hot-swappable. If you are installing only a hard disk drive (bays 1 through 5), go directly to "Internal drives installation or removing" on page 113. Otherwise, continue with the following steps. 1. If you have a modem or fax machine attached to the server, disconnect the telephone line from the wall outlet and the server. Note If you are in the United Kingdom, you must perform this step before disconnecting the power cord. Caution The Power-on switch on the front of the server does not turn off the electrical current supplied to the server. The server also might have more than one power cord. To remove all electrical current from the server, ensure that all power cords are disconnected from the power source. 2. Unplug all power cords (cables) from electrical outlets, and then disconnect all other cables from the back of the server. 3. Remove the screws from the brackets on either side of the server, and set them aside. 128 Netfinity Server HMM
