Logout
The Logout selection ends the terminal session and logs out of the system. A valid username and password 
are required before a new session can begin. The unit will also log out of a terminal session automatically 
if the session remains inactive for a certain period of time. For more information, see the section 
Privilege Level
The privilege level of the currently active terminal session is displayed in this field.
ACO Buttons
The 
ACO
 (alarm cut off) buttons turn off an active audible alarm. Since the buttons are recessed, use a pen 
or other pointed instrument to press them. Once an 
ACO
 button deactivates an alarm, the alarm remains 
disabled until the condition has cleared. 
Alarms can also be turned off remotely by using a selection found in the 
Status
 menu. For more 
information, refer to 
LED Descriptions
The MX2800 has LED status indicators for the power supplies, the DS3 state, the controller cards, and the 
individual T1s/E1s. These LEDs are identified below:
Power Supply A/B Status LEDs
The 
PWR
 LED is active when the unit is on and receiving full power. The 
CHK
 LED is active when the 
power supply is failing or is providing low power and needs to be checked.
Controller Cards Status LEDs
The 
STATUS
 LEDs apply to the two controller cards. The LEDs provided are 
ACT
 (active), 
DS3
ALM
 
(alarm), and 
PRF
 (performance). Various conditions are indicated by the state of the LED (its color and 
whether it blinks, alternates color, or is on solid). The condition descriptions vary depending on whether 
the LED represents the active controller card or the controller card on standby. The following tables 
provide LED definitions for the active cards (see 
on page 2-16) and T1/E1 cards (see
