Installing The Control Panel; Removing And Installing The Midplane - Dell PowerVault MD1120 Hardware Owner's Manual

Installing the Control Panel

1 Align the top and bottom channels on the control panel with the insert
slots on the edge of the chassis (see Figure 3-7).
2 Slide the control panel into the slot, pulling the release plunger toward the
inside of the enclosure. Once the control panel is halfway into the slot,
release the release plunger and push the panel fully into the enclosure. The
release plunger will snap into place when it seats securely into the
backplane connector.
3 Re-install any physical disks you removed (see "Removing and Installing
Physical Disks" on page 28).
4 Reconnect power cables to the enclosure and power it back on.
5 Power on the host server.
