E1/T1 PCI card installation guide
10
To install modules:
1. Fit the first module to its connectors, ensuring correct orientation and mating of the
connectors. (see the above diagram and the documentation supplied with the expansion kit)
2. Secure the module to the card using 8mm spacers and appropriate screws and washers.
(Supplied with the module when purchased as an expansion kit.)
3. Repeat steps 1 and 2 for any additional modules.
2.4.4
Installing a card into a host:
1. Remove power and disconnect any mains leads
2. Remove the host computer covers.
3. Locate a vacant full-length PCI slot and if required, remove the blanking plate.
4. Fit the card to the PCI slot and screw the bracket to the chassis.
5. Fit the H.100 ribbon cables between the E1/T1 PCI card connectors and any other cards that
are required.
6. Replace the covers on the host computer.
7. Attach the mains leads and apply power.
Following installation, the device driver will automatically detect the presence of the additional
modules.

firmware only or by firmware and links on the PM module:

Pre revision 2 E1 variant modules, require the following hardware links to be fitted for 75ohm
working:
Pre revision 1.5
Revision 1.5
Port 0 2 x J16, J6 & J10
Port 0
2 x J6
Port 1 2 x J15, J5 & J9
Port 1
2 x J5
Port 2 2 x J17, J4 & J8
Port 2
2 x J4
Port 3 2 x J18, J3 & J7
Port 3
2 x J3
•
When the jumpers associated with the E1 port are fitted. The impedance of the interface is
75 ohms
•
When the jumpers associated with the E1 port are NOT fitted. The impedance of the
interface is 120 ohms
Note
Different impedance can be supported on the same E1 variant module;
Note
The revision 2 modules can simultaneously support both E1 and T1 ports. Earlier revisions could only support either E1 or T1 as they
required different E1 or T1 variant modules.
