Replacing a 10G Expansion Module
The HP 2920 10G Expansion Modules are not hot swappable. The switch must
be powered off before replacing the module. When a 10G Expansion 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 module needs to be replaced.
To replace a 10G Expansion Module:
1. Power off the switch.
2. Remove the new 10G Expansion Module from it’s packaging, being careful
to not touch any of the circuitry on the board.
3. Disconnect the networking cables from the failed module. You do not
need to disconnect the cables from the networking devices at the other
ends of the cables.
4. Unscrew the two retaining screws on the module.
5. Insert the new stacking module fully into the slot as shown in Figure 2-7
on page 2-10. The face plate of the module will be flush with the back face
of the switch.
6. Engage the retaining screws and tighten them. Be sure to not over tighten
the screws.
7. 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.
