Juniper Networks J4350 사용자 설명서

PIMs are field-replaceable. Each PIM has a unique serial number. The serial number
label is located on the right side of the PIM, when the PIM is horizontally oriented
(as it would be installed in the router). The exact location might be slightly different
on different PIMs, depending on the placement of components on the PIM board.

The power supplies installed in the J6350 Services Router are field-replaceable. Each
power supply has a unique serial number. The serial number label is located on the
top of the power supply.
