Jumper Setting Description
PWRD_EN The password reset feature is enabled (pins 2–4).
The password reset feature is disabled (pins 4–6). The iDRAC
local access is unlocked at the next AC power cycle.

boot (pins 3–5).

Disabling forgotten password
The software security features of the system include a system password and a setup password. The password jumper enables or
disables password features and clears any password(s) currently in use.
Steps
1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
2. Remove the system cover.
3. Move the jumper on the system board jumper from pins 4 and 6 to pins 2 and 4.
4. Install the system cover.
The existing passwords are not disabled (erased) until the system boots with the jumper on pins 2 and 4. However, before
you assign a new system and/or setup password, you must move the jumper back to pins 4 and 6.
NOTE:
If you assign a new system and/or setup password with the jumper on pins 2 and 4, the system disables the new
password(s) the next time it boots.
5. Reconnect the system to its electrical outlet and turn on the system, including any attached peripherals.
6. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet.
7. Remove the system cover.
