Inserting A New I/O Module Into An Empty Slot; Replacing A Plug-In Port On The Cpu Module; Replacing A Plug-In Sram Memory Card In The Cpu Module - Motorola ACE3600 RTU Owner's Manual

Inserting a New I/O Module into an Empty Slot

When the RTU is shipped, a protective rubber cover is inserted into any empty module slots,
on the mother board connectors. The procedure below describes how to remove this cover from
the slot and insert a new I/O module onto the RTU frame.
Procedure 29-5 How to Replace an I/O Module
1. Grip the protective rubber cover (p/n 1571435Y04) firmly with your thumb and index
finger. Gradually ease the cover out of the desired module slot.
2. Insert the desired I/O module into the empty slot.

Replacing a Plug-in Port on the CPU Module

Procedure 29-6 How to Replace a Plug-in Port on the CPU Module
1. To replace a plug-in port on the CPU module, remove the CPU module from the RTU.
2. Unscrew the two supporting pins on the other side of the CPU board. Save the screws.
3. Unscrew the two supporting pins on the plug-in port. Save the screws.
4. Connect the two supporting pins with screws to the new plug-in port.
5. Replace the plug-in board with the RJ-45 connector facing the panel. Carefully insert the
plug-in board connector into the appropriate connector on the CPU board.
For Ethernet 10/100 MB, use the J14 connector on the CPU (Plug-in 1 only.)
For all other plug-in ports, use the J5 (Plug-in 1) or J6 (plug-in 2) connector.
6. Connect the two supporting pins with screws to the other side of the CPU board.
7. Replace the CPU module in the slot.

Replacing a Plug-in SRAM Memory Card in the CPU Module

Procedure 29-7 How to Replace a Plug-in SRAM Memory Card in the CPU Module
1. To replace an SRAM memory card on the CPU module, remove the CPU module from the
RTU.
2. Remove the old plug-in SRAM memory card from the board.
3. Place the new plug-in SRAM memory card with the connector facing the panel. Carefully
insert the plug-in board connector into the connector marked P12 on the CPU board.
4. Secure the memory card to the CPU board with the supplied screw.
5. Replace the CPU module in the slot.
