Installation
Upon receipt of the equipment, visually inspect it for signs of damage. If the
equipment has been damaged in transit, immediately report the extent of
damage to the transportation company and to PairGain Technologies (see
Technical Support on page 16).
HLU-231 Card-Edge Connectors
The HLU-231 card-edge connector pinouts are shown below. The following
rules apply to the HLU-231 card-edge connector:
•
If the shelf uses pin 23 remove resistor R39 from the HLU-231 board.
This removes the burn-in circuit from pin 23.
•
The HLU-231 uses pins 20 and 21 as alarm-relay output. The Kentrox
220 T-Term shelf uses the same pins for external equalizer output. If the
HLU-231 is installed into a Kentrox shelf, the HLU-231 ALM option
must be disabled (see Provisioning on page 6 for further information).
