Dual Trunk Card Memory Upgrade
• If U17 is a 28-pin socket with a 28-pin RAM chip in it, then they must both be
replaced. While you might be able to do this in the field, Zetron recommend that
you contact the factory and arrange to return the card so that our technicians can do
the work here.
• If the socket in U17 is a 32-pin socket with only a 28-pin RAM chip installed, then
only the RAM needs to be replaced with a larger unit. This upgrade can reasonably
be accomplished in the field. Contact Zetron and inquire about dual trunk card
upgrade option, part number 950-0222.
• If U17 is a 32-pin socket and there is a 32-pin RAM installed, then no upgrade is
needed. The dual trunk card already has the larger capacity RAM installed.
