MSL6000 series pass-through mechanism reference guide 31
Installing the Extended PTM
To install the extended PTM:
1. Use the handle while supporting the PTM base unit from the bottom (see Figure 9 on page 20).
2. Carefully insert the extended PTM into the top library making sure the top pins are fully
engaged.
3. Using the PTM extension thumbscrews, secure the extended PTM to the top (master) library.
NOTE: If the lower pins are difficult to align to the bottom (slave) libraries, push the slave libraries
slightly forward. Afterwards, engage each one by pulling them (one at a time) toward the extended
PTM and then tighten the appropriate thumbscrews.
NOTE: On 10U libraries, the middle holes on the unit are not threaded and are not intended to
engage the thumbscrews. The top and bottom thumbscrews secure the PTM extension to the library.
4. Using the PTM extension thumbscrews, secure the extended PTM to the remaining libraries (in
sequence) for the multi-unit library configuration.
NOTE: If you still cannot align a bottom (slave) library to the extended PTM, slightly loosen the rear
rail bracket screws for that library, reposition it, and then secure it to the extended PTM. Afterwards,
re-tighten all rear rail bracket screws.
5. If required, install any previously removed drive assemblies and covers.
6. If necessary, tighten the thumbscrews at the front of the unit.
7. You can now attach the data cables to the extended PTM. See the section on ”Cabling the PTM
and LAN Hub” on page 31.
Cabling the PTM and LAN Hub
This section describes how to connect the data cables to the PTM and LAN hub in a multi-unit library
configuration (single master and slave).
CAUTION: Do not apply power to any library until cabling is complete. Attempting to connect or
disconnect a PTM to a library that has power applied can damage the library and the PTM PCB.
After connecting all the appropriate data cables, see ”Configuring the PTM” on page 35 for
detailed information about configuring the PTM using the GUI touch screen.
