It is assumed that you have already installed the HotWire Model 7900 Nest and
associated power supply in a standard equipment rack, and that all network
connections have been made. Installation of the optional HotWire 7900 Basic
Maintenance Processor (HTU-M or HTU-S) is described in a separate user's
guide. Refer to Product-Related Documents
Procedure
To install the nest card:
1. Use electrostatic discharge (ESD) protection when handling the electronic
components. Remove the card from any protective packaging.
2. Align the circuit board with the top and bottom card guides of the next
available card slot:
— Slot 1 if no maintenance processor option is installed
— Slot 2 if an HTU-S is installed in Slot 1
— Slot 3 if an HTU-M is installed in Slots 1 and 2
3. Slide the nest card into the slot until the backplane connector plug is seated
firmly into the backplane.
4. Tighten retaining screws at the top and bottom of the nest card front panel.
