Lock
The protective grid can also be removed, but you will have to use a little
force. Since the filter is replaced while the PC is operating, the protective grid protects you from injuring yourself on the sharp edges of the fan and
prevents the filter pad from being sucked into the fan.
Caution
!
When the fans are operating, particles can be drawn into the system unit. The protective grid may only be removed with the PC switched off.

1.3.2 Removing the Protective Sliding Cover

Notes
Please note the following if the protective cover has to be removed:
When the fan cover is in place, the protective cover can only be moved to
the left as far as it will go. In this position, in case you forgot to move the protective sliding cover back, a limited amount of air can still be drawn in.
If you first removed the fan cover you can slide the cover completely off its
guides.
If the protective sliding cover is completely closed (all the way to the right),
access to drives can be prevented.

1.3.13 Connecting the Multipoint Interface (MPI/DP)

System Unit
Connecting a PROFIBUS-DP Network via MPI /DP Interface
!
You can connect youR IPC to a PROFIBUS-DP network via the optically isolated* MPI/DP interface. The connection is established via any stationary connecting PROFIBUS components or via an MPI connecting cable (5 m) (Order No.: 6ES7001-0BF00-0AA0). The PROFIBUS components and MPI connecting cable are not included with the IPC and have to be ordered separately. The MPI connecting cable (5 m) can only be employed for data transfer rates up to 187.5 Kbps.
You connect your IPC to a PROFIBUS-DP network as follows:
1. Switch off your IPC.
2. Plug the connecting cable (of the PROFIBUS components or MPI connecting cable) into the MPI/DP socket of your IPC and tighten the connector by means of screw-type locking.
3. Switch on your IPC.
Caution
Risk of damage to the unit! Before plugging in the connecting cables, you must discharge the
electrostatic charge of the cables and of your body by briefly touching a grounded object (ESD guidelines).
PROFIBUS-DP Network
You can network up to 32 devices (PC, programming device, programmable logic controller, or DP components) via the MPI/DP interface in one seg­ment. The interconnection to the PROFIBUS-DP segments is established via an optically isolated* RS 458 port, which is part of the interface.
You can interconnect several PROFIBUS-DP segments via a repeater. The entire PROFIBUS-DP network has a maximum capacity of 127 stations.
The data transfer rate of the MPI network is 187.5 Kbps. The data transfer rate that can be achieved via the MPI/DP interface in the PROFIBUS-DP network ranges from 9.6 Kbps up to 1.5 Mbps.
Note
For further information on configuring a PROFIBUS-DP network, please refer to the “S7-300 Programmable Controller, Hardware and Installation” manual, Order No.: 6ES7030-0AA00-8BA0.
*Optically isolated within safety extra-low voltage circuit (SELV)
