Safety, Installation, and Use Precautions
Provide power to the switch enclosures only with a 3-wire, IEC line cord from an outlet that
includes a safety ground. The input power is 100–127 V~ or 200–240 V~, 50Hz or 60Hz. All
switch enclosures are shipped with a power cord appropriate to the unit and to the shipping
destination. The power cord should be rated for 10A except for 100–127V~ power cords for the
M3-E128, which are rated for 15A.
An M3-E128 switch enclosure fully populated with line cards weighs approximately 31 kg (68
pounds). Two people are required to mount this unit in a rack. One person should not attempt to
install an M3-E128 switch unit in a rack. The rack mounting holes conform to the EIA-310
standard for 19-inch racks.
Line cards and the fan tray may be “hot swapped” (inserted or removed with the power on).
However,
•
Insert and remove line cards gently, according to the instructions that start on page 4.
•
Do not operate a switch for extended periods with missing line cards. Use M3-BLANK
panels to fill in any empty line-card slots. The front of the enclosure needs to be closed
both for the efficiency of the fan cooling and to avoid electromagnetic interference
(EMI).
•
Each line card includes thermal sensors. Operating the switch without a fan tray for more
than one minute may result in line cards turning themselves off.
Configurations with optical-fiber Myrinet ports are
Class I Laser Products
. Optical-fiber
components with this classification pose no threat of biological damage.
