Using the Enclosure Manager physical interface
The primary interface to the Enclosure Manager is the Ethernet LAN port, which is intended for
remote management of the enclosure. AC power is applied to the enclosure so that auxiliary power
is available to the EMU. The enclosure may or may not be powered on. Solution software may or
may not be installed.
Manual button functions
IMPORTANT: Use the following manual button functions only with the assistance of HP Technical
Support.
The two manual buttons and a two-digit LED display on the EM provide basic management functions
when the EM is not connected to the network. Figure 150 (page 161) illustrates the physical
(touch/visual) interaction elements.

Activate Button Menu
You cannot manage the EM using a remote management interface because the system is not
connected to the LAN, the LAN interface is not functioning properly, or management software is
not installed or available.
To activate the button menu:
1. Press and hold the UP (right) button until the two digits display “- -“.
2. Release the UP button. System displays two underscores “_ _”:
This display indicates context is at the bottom of the menu range and is awaiting menu selection,
which requires pressing the UP button one or more times.
Reboot EM (bE)
The EM LAN interface is not responding to the remote management software but is configured to
do so, or the EM has just been reconfigured and needs to be rebooted for the configuration to
take effect.
To reboot the EM:
1. Enter the menu mode using the Activate Button Menu” (page 161).
2. Press the UP button one time.
The EM changes the display from “_ _“ to “bE” to indicate that menu choice 0 (Reboot) is
selected.
3. Press and hold the UP button for three seconds.
The system blinks (or flashes) the two “bE” for one second to acknowledge the selection.
4. Release the UP button.
The system then reboots the EM. This event is logged in the system log. The display shows “-
-” during the reboot. The module fault LED flashes. When the reboot is complete, the EM green
health LED is lit steady, and the enclosure ID is displayed on the two digits.
