Caution
The control module should not be replaced while the Stinger MS+ unit is in
operation. Hot-swap replacement of an active control module causes a Stinger unit to
crash.
Removing a control module
To remove a control module:
1
Put on the antistatic wrist strap, as recommended in “Preventing static discharge
damage” on page 1-4, and plug it into the ESD grounding jack located on the
front of the Stinger unit. (See Figure 1-5 on page 1-7.)
2
If the unit does not contain a redundant control module, or if both the primary
control module and the secondary control module are being replaced
simultaneously, notify all users that the unit is being shut down.
3
Turn off power to the unit.
4
Using a number 2 Phillips screwdriver, loosen the thumbscrews located on each
side of the control module, as shown in Figure 6-1. Other screwdrivers might
damage the screw heads.
5
Slide the ejector lock on the left side of the control module to the right to access
the card ejector. This puts the module into a reset state.
