Clear-Com HX System Frames - Manual (Page 30)

Danger of explosion if battery is incorrectly replaced. Replace only with
the same or equivalent type.
Lithium batteries can overheat or explode if they are shorted. When handling
the CPU card or a loose battery, do not touch any external electrical
conductors to the battery’s terminals or circuits to which the terminals are
connected.
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-Median
The following overview gives a summary of the steps required to install an Eclipse HX-
Median matrix. More detailed information on each step is provided in the sections that follow.
To install an Eclipse HX-Median:
1. Remove the Eclipse HX-Median matrix chassis from its shipping carton.
2. Install the Eclipse HX-Median 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.
3. 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.
4. Apply AC power to the unit. The unit has two separate AC power entry connectors for
the two separate power supplies in the system.
