Description of the Upgrade
Installation Procedure for the Upgrade
4. Follow the eleven instructions shown in
Graphics in this document such as
where to connect a cable. For example, text that reads "N5242-60018
IFMUX P201 - BRK1 B" means to connect the N5242-60018 gray flexible
cable at the A20 IF MUX board connector P201 and at A23 Mixer Brick 1
connector B.
Figure 3
A23 and A24 Mixer Brick Assembly (cont.) – (0960-0055, 5087-7139
N5242-60019, N5242-60020, N5242-60021, N5242-60022, N5242-60023,
and N5242-60024)
1. The A22 splitter (5087-7139) and N5222-20007, N5222-20008, and N5222-20009 cables are only used with
a legacy HMA26.5 p/n: 5087-7765. If your PNA has a new N5240-60101 assembly installed, then set aside
these parts as spares for use in other PNAs with the older HMA26.5 installed or discard. If you are unclear
which HMA26.5 assembly your PNA has installed, refer to
22
Option 029A, omit instruction 2 and the unnumbered instruction to install
a splitter - it is already installed. New parts are listed in
page 13
of this document.
