1 5 Rack handles
If your server is installed in a rack cabinet, you can use the rack handles to help you slide the server out of
the rack cabinet. You also can use the rack handles and screws to secure the server in the rack cabinet so
that the server cannot slide out, especially in vibration-prone areas. For more information, refer to the Rack
Installation Instructions that comes with your server.
2 Front panel
For information about the controls, connectors, and status LEDs on the front panel, see "Front panel"
on page 21.
3 Pull-out information card
The machine type, model, and serial number label of the server is attached on the pull-out information card.
See "Machine type, model, and serial number label" on page 15.
4 2.5-inch-drive bays (0–23)
The EMI integrity and cooling of the server are protected by having all drive bays covered or occupied.
The number of the installed drives in your server varies by model. The vacant drive bays are occupied
by dummy trays.
When you install drives, follow the order of the drive bay numbers.
Depending on your server model, all or some of the drive-bay groups, such as bays 0–7, bays 8–15, and
bays 16–23, might be covered by EMI-protective panels as a whole.
