3.5 Maintenance
This section describes the following maintenance operations:
Replacing modules (refer to Section 3.5.1 on page 42)
Inserting additional modules (refer to Section 3.5.2 on page 43)
Replacing the Fan Tray unit (refer to Section 3.5.3 on page 43)
3.5.1 Replacing Modules
The Mediant 1000 I/O modules are hot-swappable (except for the OSN Server modules --
refer to Appendix H on page 425). The replacement of Mediant 1000 communication
modules (i.e., digital, FXS, and FXO) is performed using the Mediant 1000 embedded Web
server. Once you have 'removed' the module using the Web server, you need to physical
remove and then insert a new module. Once the new module is physically inserted, you
then need to 'insert' it using the Web server.
Warnings:
• Replacing of a damaged module can be performed only with the same
module and in the exact module slot (e.g., a module with two digital
spans in Slot 1 must be replaced with a module with two digital spans
in Slot 1).
• When only one module is available, removal of the module causes the
device to reset.
¾ To replace Mediant 1000 modules, take these 4 steps:
1. Remove the module using the embedded Web server (refer to Section 5.10.9 on page
205).
2. Physical remove the module from the Mediant 1000 front-panel slot, by performing the
following:
a. Using a flathead screwdriver, loosen the module's two mounting screws.
b. Gently extract the module from the slot.
3. Physical insert the new module into the same slot from where the module that you are
replacing resided, by performing the following:
a. Insert the module into the empty slot, with the plain side of the Printed Circuit
Board (PCB) facing up. Make sure the PCB slides into the slot rails by aligning
the module with the rails in the slot.
b. Push the module into the slot and press on it firmly to ensure it has been fully
inserted.
c. Using a flathead screwdriver, tighten the module's mounting pins.
4. Insert the module using the embedded Web server (refer to Section 5.10.9 on page
205).
