Symmetricom XLi IEEE 1588 manual Rack Mounting the XLi

SSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSSS

Note: The IEEE 1588 card configured as a PTP slave relies on TAI as the time scale of the PTP master. Distributing non-TAI time over PTP while the PTP slave is a reference source will have a predict- able effect on the XLi’s system time.

Note: Later on, when reconfiguring the IEEE 1588 card as a PTP master, use F119 to set the GPS receiver as the PRIMARY reference source. (In F119: Set GPS TIME REFERENCE, BAY 1 to PRIMARY.)

Note: For XLi IEEE 1588 Clocks with the second IEEE 1588 card in Option Bay 2 (preconfigured a PTP slave, configure the network settings, PTP SYNC INTERVAL, PTP BURST MODE, and PTP SUBDOMAIN. The factory settings are the same as for the PTP master, except the static IP Address is 010.048.000.105 and Clock Configuration is Slave Primary.

Rack Mounting the XLi

The XLi comes with the following parts needed to mount the XLi securely in any EIA standard 19-inch

(48.26-cm) rack:

•2 mounting brackets

•4 flat-head, Phillips screws

Have the following items ready and available:

•The appropriate AC source to connect to the XLi’s power supply.

•A #2 size Phillips bit screwdriver

To rack mount the XLi:

•Unscrew the four phillips-head screws from the front end of the side panels.

•Use the same screws to attach the rack mount brackets, as shown.

•Tighten the screws using a #2 size Phillips screwdriver.

•Position the XLi in any EIA Standard 19-inch (48.26 cm) rack system, and line up holes in the brackets with the holes in the rack.
