Replacing or inserting an MP20 or MP80 VoIP module
The G450 has four slots for media resources modules. Each slot can accommodate either an
MP20 or an MP80 DSP daughterboard, each providing 20 or 80 VoIP channels, respectively.
The basic configuration includes one MP20 or MP80 daughterboard in one of the four slots. You
can replace an MP20 or MP80 daughterboard or insert one into an empty slot.
The slots are located on the G450 main board. You must pull out the main board to remove or
insert a media resources module. The G450 supports hot insertion and removal of the main
board without power drop. However, all services are suspended while the G450 main board is
out, and all calls are disconnected. Any translation and other data that is in the running
configuration but has not been saved to the startup configuration is lost.
This procedure requires the following steps:
1. Removing the main board
2. Removing an MP20 or MP80 module — Skip this step if you are inserting a daughterboard
into an empty slot.
3. Inserting an MP20 or MP80 module
4. Reinserting the main board
Removing the main board
ELECTROSTATIC ALERT:
ELECTROSTATIC ALERT: Hold the module only by the edges to avoid damage from static electricity. Do not
touch the top or bottom of the circuit board. If possible, wear a wrist-strap and use
an anti-static bag.
!CAUTION:
CAUTION: The connector pins can be bent or damaged if the module is handled roughly, or if
misaligned and then forced into position.
To remove the main board:
1. Unscrew the two captive screws, one at each side of the main board front panel (see
Figure 1).
2. Open the latches on both sides of the main board.
3. Grasp the latches and pull out the main board from its slot.
4. Place the main board carefully on a table.

2. Push the module in all the way. Do not use too much force.
3. Flatten the module so it is flush with the main board. The latches at both sides click shut.
Reinserting the main board
To insert the main board:
1. Open the latches on both sides of the slot.
2. Insert the main board vertically into the slot.
3. Push the main board in until the latches begin to close.
4. Close the latches.
5. Close and tighten the two captive screws on the front panel.

6. Use the show platform mainboard CLI command to make sure everything is OK. For
example, when the main board is successfully installed, the output includes:
When a VoIP module is successfully installed in a given VoIP module slot, the output for the

Replacing the fan tray
The fan system is field replaceable. It is mounted on a fan tray that can be replaced as one unit.
The G450 supports hot swap of the fan tray. There is no need to power down or reset the G450
when replacing a faulty fan tray unit.
Prepare the new fan tray for insertion before removing the current the fan tray: take the new fan
tray out of its package and place it nearby.
!Important:
Important: Replace the fan tray within one minute, to avoid overheating the G450. If the
G450 exceeds its allowed heat level, it shuts down.

Replacing a power supply unit
The G450 provides full redundant, load sharing power supply units (1 + 1). A single power
supply unit (PSU) provides sufficient power for any G450 configuration. If you choose to install
two PSUs, they operate in a load sharing mode.
The G450 supports hot swap of the PSU. Even if you have only one PSU installed, there is no
need to power down or reset the G450 when replacing a faulty PSU. You can install the
replacement PSU in the second PWR slot, and it will become the active PSU once you remove
the faulty PSU.
Figure 5: Replacing a power supply unit
To remove a PSU:
1. Disconnect the G450 power cable from the mains socket.
2. Disconnect the G450 power cable from the power connector, located on the front panel of
the PSU, at the rear of the G450.
3. Loosen the two captive screws, one on each side of the PSU.
4. Grasp the two side handles and pull the PSU out of its slot.
To insert a PSU:
1. Position the PSU before the opening and engage both sides of the unit in the interior
guides.
2. Slide the PSU slowly into the chassis, maintaining an even pressure to assure that the unit
does not become twisted or disengaged from the guides.
3. Close and tighten the two captive screws on the front panel.
4. Connect the power cable to the power connector on the PSU.
5. Plug the power cable into a mains socket. When the PSU is powered, the green LED on the
PSU panel lights.

6. After powering up, use the show platform power CLI command to make sure
everything is OK. The upper PSU is referred to as PSU #1, and the lower PSU is PSU #2.
For example:
G450-001(super)# show platform power
