Replacing or Upgrading Memory
The appliance has four dual inline memory-module (DIMM) sockets that are double data rate
(DDR2), which perform at high speed. This section describes how to upgrade or replace the
memory by using a Nokia-approved memory upgrade kit.
The IP561 comes with 1 GB of RAM in two 512 MB DIMMs and can be upgraded to 2 GB of
RAM by the addition of a pair of 512 MB DIMMs.
Note
You must upgrade the memory in pairs of 512 MB DIMMs.
Nokia products support only memory kits purchased from Nokia or Nokia-approved resellers.
For further information, contact the appropriate Nokia customer support site listed in
“Nokia
Contact Information” on page 3.
The DIMM sockets are located on the left rear of the IP561 appliance motherboard, as you look
at the appliance from the front, as
Figure 22 shows.

slots J1/J2 and/or J3/J4, otherwise the DIMMS do not work. You can also use all four slots at
one time.
