Replacing the Stacking Module
The E3800 Stacking Module is not hot swappable. The switch must be powered
off before replacing the module. When a stacking module fails, the Module
Status (Mdl) LED on the front of the switch and the Module Status LED on the
module will blink orange simultaneously with the switch Fault LED. In this
case, the stacking module needs to be replaced.
To replace a stacking module:
1. Power off the switch for which the stacking module needs to be replaced.
1. Remove the new stacking module from it’s packaging, being careful to
not touch any of the circuitry on the board.
2. Disconnect the stacking cables from the failed module. You do not need
to disconnect the cables from the switches at the other ends of the cables.
3. Unscrew the two retaining screws on the module.
2. Pull the two extractor handles toward you and outward until they stop
and then pull the module straight out.
3. Insert the new stacking module fully into the slot as shown in Figure 2-5
on page 2-8. The face plate of the module will be flush with the back face
of the switch.
4. Close the two extractor handles all the way until they stop.
5. Engage the retaining screws and tighten them. Be sure to not over tighten
the screws.
6. Power on the switch and make sure the module passes its self test. See
Table 2-1 on page 2-9 for the module LED behavior that indicates correct
installation.
