1 PPS signal at the top of each second
Caution
The clock module is not hot swappable. You must power down the switch before installing
any VIM modules.
Note
The TM-CLK module has no inputs for timing signals, and it cannot act as a 1588v2
grandmaster clock. The module provides no RJ45 Building Integrated Timing System (BITS)
output, and in particular does not provide the serial time of day output.
Note
The X460-G2 TM-CLK clock module does not accept both 10MHz and 1PPS signals at the
same time, so it can take 10 to 20 minutes or more to lock onto a 1588v2 1PPS signal from the
Apollo2 chip in addition to the usual 15 minutes or more for the 1588v2 servo to lock onto the
remote grandmaster clock.
