Clear-Com
Eclipse Omega Instruction Manual 7 - 9
E-Que cards and E-Fib cards normally use a different port allocation
and do not use any of the audio port allocation. E-Que cards have 60
ports in E1 mode or 48 ports in T1 mode, while E-Fib cards can be
configured to use between 16 and 192 ports. If E-Que, LMC-64 or
E-Fib cards are incorrectly installed to the left of MVX-A16 or IVC-32
cards they will be allocated ports from the audio port count, thereby
reducing the number of audio ports available to be allocated to
MVX-A16 or IVC-32 cards.
Comfort tones also use 3 ports which normally default to using the top
of the physical port range. If required the comfort tones can be
redirected to ports above 240 in System Preferences (see the Eclipse
Configuration Software manual part 810299Z).
To install an expansion card
1. Carefully place the card in the appropriate slot. Make sure the card
is aligned with the top and bottom precision guides.
2. Push the card toward the backplane connectors.
3. When the card has almost reached the backplane connectors, open
the two ejector tabs, allowing them to clear the edges of the matrix.
Gently insert the card further until it touches the backplane
connector guides.
4. Gently close both ejector tabs at the same time, which will propel the
card into the backplane connectors.
To remove an analog port or expansion card from the matrix
1. The two card ejector tabs, located at the top and bottom of the card,
hold the card in place in the matrix. To remove a card, open the two
ejector tabs at the same time until the card unseats from its
backplane connectors.
2. Pull the card out of the matrix.
STATIC SENSITIVITY
A circuit card’s components include CMOS chips that are sensitive to
static electricity. Before touching a card first touch a grounded metal
object, such as any unpainted surface on the matrix, to dissipate static
electricity.When handling a card, be careful not to bend any of the
card’s connector pins or component leads.
Store spare cards in electrically insulated packaging such as anti-static
heavy duty plastic bags or in unused port card slots in the matrix.
HOT PATCHING
Analog port and expansion circuit cards are “hot patchable” and “self
initializing”, meaning that a faulty card can be removed and replaced
while the system is powered, having no effect on any part of the
system operation, except to the analog port card’s assigned sixteen
ports.
NOTE: If the ECS computer
does not have a serial port,
and only offers USB,
adapters are generally
available from computer
parts suppliers.
