2.2 Wirewrap Panels
2.2.1 Existing and New
If using an existing panel (e.g., 090-41902-01), leave the panel in the rack,
and remove the ribbon cables from the panel before mounting the shelf in
the rack.
For the master shelf, if installing a new panel, mount the panel in the rack
after mounting the shelf in the rack. Mount the panel just above or below
the shelf, leaving enough space (2 RU) for cable management above and
below the wirewrap panel.
If you are installing an expansion shelf, mount one wirewrap panel above
the expansion shelf and the other below the expansion shelf, leaving enough
space (2 RU) above and below each wirewrap panel.
2.3 Timing Output Guidelines
2.3.1 Output Connector Modules
On the master and remote shelf, up to seven output connector modules can
be installed per shelf. For DS1 outputs, use DS1 Output Connector
modules; for CC outputs, use CC Output Connector modules (refer to the
Ordering and Parts List section for part numbers).
Output connector module types can be distinguished by the handle on the
card. Each DS1 Output Connector module is labeled “DS1” and has a black
handle; each CC Output Connector module is labeled “CC” and has a blue
handle.
Output port designations are as shown in Figure 2-2. Each letter indicates a
group of 40 ports and each number indicates a port.
For the expansion system, up to 16 output connector modules can be
installed per shelf. For DS1 output signals, use DS1 output modules for the
expansion shelf. For CC output signals, use CC connector modules for the
expansion shelf (refer to Table in this section).
Output port designators are shown in Figure 2-3. Each letter indicates a
group of 40 ports and each number indicates a port.
