How to Recover from a Lost Password
Overview
If the
User Name
or
Password
becomes unknown, you can use
a local computer to restore access to a Management Card that
uses the APC AOS module, version 3.0 (or later). The latest
AOS version is available at the APC web site (www.apcc.com).
Recovery
procedure
1. Select a serial port at the computer to be used for a terminal-
emulation connection with the Management Card.
2. Disable any service that currently uses that serial port, such
as PowerChute
plus
or UNIX Respond.
3. Connect the smart-signaling cable (940-0024) that came
with the Management Card to a serial port on the computer
and to the serial port on the UPS or chassis.
Note:
If the computer uses smart-signaling PowerChute
plus
, you do not need to perform step 3: A smart-
signaling cable (940-0024 or 940-1524) is already
installed. For simple-signaling, temporarily replace
the PowerChute
plus
cable.
4. Run a terminal program (such as HyperTerminal).
5. Configure the serial port for 2400 bps, 8 data bits, no parity,
1 stop bit, and no flow control, and save the changes.
6. Press
E
NTER
to display the
User Name
prompt (you may
need to press
E
NTER
two or three times).
7. Press the reset button on the Management Card.
8. Press
E
NTER
to redisplay the
User Name
prompt.
9. Use
apc
for both the
User Name
and
Password
to log in.
Note:
If you take longer than 30 seconds to log in, you will
need to repeat steps 6 through 8.
10. Select
System
from the
Control Console
menu.
11. Select
User Manager
from the
System
menu.
12. Select
Administrator
from the
User Manager
menu and
follow the on-screen instructions to change the
User Name
and
Password
settings to the new values.
13. Press
C
TRL
-C
to exit to the
Control Console
menu.
14. Log out to save the changes.
15. If necessary, reconnect the simple-signaling PowerChute
plus
cable replaced in Step 3.
16. Restart any service disabled in Step 1.
