Note: When servicing the battery, make sure that the jumper on CON9 is connecting
pin 2 (common) to either pin 1 (on) or to pin 2 (off). If the common is left
floating, the CPU may behave unpredictably. For example, the microprocessor
may reset itself intermittently.
4.2 Installing the Eclipse HX-Delta
The following overview gives a summary of the steps required to install an
Eclipse HX-Delta matrix. More detailed information on each step is provided in
the sections that follow.
To install an Eclipse HX-Delta:
• Remove the Eclipse HX-Delta matrix chassis from its shipping carton.
• Install the Eclipse HX-Delta to the standard 19 inch rack.
Environmental note: Leave clearance on all sides of the matrix chassis
to ensure proper airflow. Do not block ventilation vents.
• Check the position of CPU cards and interface cards, power supplies, and
rear connector panels. Later sections in this chapter give more
information on these items.
• Apply power to the unit using the two external power supplies.
4.2.1 Installing the external power supplies
The Eclipse HX-Delta's power is provided by two external 12V power supply units
(for redundancy). The power supplies have separate connections to the rear of
the matrix (see 4.4.3 Combining interface cards in the matrix).
Each of the power supplies must be connected to a dedicated branch of AC
mains power. The matrix will continue to operate even if one of the power
supply units fails.
When the matrix is installed to the rack, connect the power cables from the
external power supplies to the power connectors on the rear of the matrix.
The power cables connecting the supplies to the matrix can be up to 1.5m in
length, and are capable of sustaining a pull test of 10 Newton’s. The power
cables are secured to the matrix by latching connectors.
When the matrix is connected to the power supplies, connect the power supplies
to AC mains power.
A fully equipped Eclipse HX-Delta matrix (2 CPU cards, 4 interface cards and 3
interface modules) requires 100 - 240 VAC at 50 - 60 Hz with a maximum
dissipation of 175W.
