Lift the top and bottom card ejectors simultaneously to remove the module from the unit.
Lift both ejectors simultaneously to avoid damage to the module.
5
Carefully slide the LPM out of the unit and place it into an antistatic container.
6
Align the new or replacement LPM with the card guides and carefully slide the module
into the unit. Press firmly to be sure it has engaged the midplane connectors.

Depress the ejectors simultaneously.

Using a number 2 Phillips screwdriver, secure the module into the unit by tightening the
thumbscrews on the LPM.

Reconnect the cables, as described in “Connecting cables to a Stinger unit” on page 2-4.
Replacing the fan tray
Stinger FS+ chassis manufactured since late 2005 have a fan tray that can be easily
replaced from the front of the chassis. See Figure 1-3 on page 1-5.
Before replacing the fan tray, all power must be removed from the unit. At a
minimum, replacement of the power filter also requires the removal of the
ventilation screen and air filter from the front of the chassis. You may also decide
remove other modules during this process to provide greater access or visibility.
Replacement of a power filter in a Stinger FS or Stinger FS+ chassis should only be
performed by a qualified Lucent technician.
!
Caution
The fan tray contains moving parts that can cause injury. Wait until the
fans have stopped moving before completely removing the fan tray.
