PPC/PMC-8260/DS1 xxv
Operation
While operating the module ensure that the power and environmental
requirements as given in the “Requirements” section on page 2-4 are met.
When operating the carrier board and the PMC module in areas of electro-
magnetic radiation ensure that the carrier board is bolted on the VME or
CompactPCI system and is shielded by enclosure.
Make sure that contacts and cables of the module cannot be touched while it is
operating. Touching contacts can cause contact oxidation and reduces conduc-
tivity and touching power pins is dangerous.
Do not operate the product outside the specified environmental limits. High
humidity and condensation may cause short circuits. Make sure the product is
completely dry and there is no condensation of water on any parts of the
board’s surface before applying power. Do not operate the product below 0°C.
RJ-45 Connector
Connecting a telephone or Ethernet to the RJ-45 connector of the PMC-
8260/DS1-H110-F and SC-F variants causes damage to the telephone, the
PMC module and to attached devices. Therefore, only connect E1/T1/J1 lines
to the RJ-45 connector using a Digital Service Unit / Control Service Unit
(DSU/CSU).
Environment
Always dispose of old modules according to your country’s legislation, if possi-
ble in an environmentally acceptable way.
