Installing SIMMs 5. Install the SIMMs into the memory sockets. First identify the sockets you will install the SIMMs into. There are four sockets, divided into two banks. The two sockets for bank 1 are labeled 1, and the two sockets for bank 2 are labeled 2. Bank 1 must be filled first, and then if necessary you can proceed to fill bank 2. (The labels 1 and 2 are located at the left side of the slot when viewed from the front panel.) 1 2 NOTE: Although the above illustration does not show the SCSI board mounted in the A3000, please note that there is no need to remove the SCSI board when installing SIMMs. If you are using different SIMM sizes in the two banks, the larger size must be installed into the Bank 1 sockets to ensure that the A3000 handles the memory correctly. For example, if you are adding one pair of 32MB SIMMs and one pair of 8MB SIMMs, you must install the 32MB SIMMs into Bank 1. If you already have SIMMs installed in Bank 1 and are now adding a larger pair, you will need to move the original pair into Bank 2 and insert the new pair into Bank 1. When inserting SIMMs, always begin with the free socket furthest from the A3000 front side. (SIMMs will not fit into the sockets if you reverse this order.) Hold the SIMM with its cutout part facing to the left (as viewed from the front panel), and set it into the socket at an angle as shown in Figure 1. Then push in direction shown in Figure 2 so that it becomes upright and the hook snaps into place. (1) 314 Appendix
