Removing Modules from the Chassis
The modules installed in the PSAX 2300 system can be replaced, or “hot swapped”,
while the power is applied and without disrupting service on the other modules in the
system. These procedures assume redundant common equipment modules are
installed.
Note:
If a replacement module is not being immediately inserted into the empty
slot, insert a blank faceplate module into the slot to maintain optimum
EMI shielding and proper ventilation for the chassis. Ordering information
on the blank faceplate modules can be found in Appendix B.
WARNING:
!
Blank faceplates must be installed in empty slots to minimize EMI and maintain
proper air flow through the chassis.
