Operating Features of the Power Supply
The ACPS-17HS and DCPS-17HS load-sharing power supplies are designed for AC and DC power sources, respectively. Both power supplies are field-replaceable.
When two power supplies are installed in a Metrobility 17slot chassis, they operate in tandem and share the load. If the
power source to one of the supplies fails or is removed, the
other power supply automatically provides the entire power
load to the chassis. This setup provides both the chassis and
the network with uninterrupted service. It also decreases the
demand placed upon an individual power supply, thus prolonging its life.
When the power (PWR) LED on the front panel of the power
supply is lit, it indicates that the power supply is turned on,
connected to an active power source, and providing power to
the chassis’s backplane. Because they are load-sharing, when
two power supplies are installed and active in a single chassis, the LEDs on both supplies are lit simultaneously.
An optional display card is available for visible verification of operating status from the
front of the chassis. The 7500-D, which
must be installed in slot 16 or 17, provides
two LEDs labeled A and B. When lit, these
LEDs indicate that their corresponding
power supplies are installed properly, connected to an active power source, turned on,
and providing power to the chassis’s
backplane. When two power supplies are installed and active in a single chassis, both
LEDs are lit simultaneously.

Installation and User Guide
Models: ACPS-17HS / DCPS-17HS
Installing the Power Supply
Follow the steps outlined below to install the ACPS-17HS or
DCPS-17HS power supply in any 17-slot Metrobility chassis.
IMPORTANT
• Disconnect all power sources before
installing or removing the power supply.
• A blank panel must remain installed in
any empty power supply slot.
• Do not apply power to the power supply
while it is out of the chassis.
1. Remove the blank panel from the back of the chassis.
2. Insert the power supply into the slot. Do not force it into the
chassis unnecessarily. It should slide in easily and evenly.
3. Push gently until the face panel is flush with the chassis.
4. Turn the thumb screws clockwise and tighten to secure the
power supply into the chassis.
Applying Power
DC Power Supply (DCPS-17HS)
IMPORTANT
• For installation in a restricted access location only.
• A readily accessible disconnect device must be
incorporated in the building installation wiring.
For DC power supply connections, follow these guidelines:
• Make sure the power switch is in the OFF position (O).
• Remove the plastic safety cover to expose the terminals.
• Connect the wire leads to the appropriate terminals. There
is one each for a positive, a negative and a chassis ground.
To make a connection, loosen the terminal screw, insert
the exposed wire, then tighten the screw. If two power
supplies have been installed, connect each power supply to
a separate power source.
• Replace the plastic safety cover over the terminal block.
• Set the power switch to the ON position (I).
• Verify proper connection and operation via the power
(PWR) LED on the power supply front panel. The LED is
lit when the power supply is functioning correctly.
Important: The terminal block safety cover must be installed
when power is present to prevent burn or energy hazards.
Caution: A fully loaded chassis is rated for 4.9A DC
maximum current. Make sure that the power supply current
available is sufficient to power the chassis. Refer to front
panel text for voltage/current ratings. The center terminal
connector provides grounding for the chassis and must be
maintained. Particular attention should be given to power
supply connections other than direct connections to the
branch circuit (e.g. use of power strips).
Note: The DCPS-17HS is designed to protect against
overheating. The power supply will go into thermal shut-down
mode if it is operated above the specified temperature of 50°C.
Normal operation can be reestablished once the temperature
drops to the specified range by power cycling the unit.

AC Power Supply (ACPS-17HS)
The ACPS-17HS includes a standard North American 3-pin
power cord which is UL (USA), CSA or CUL (Canada) listed
or approved. For installation in regions outside North
America, replace the power cord with a cord approved by appropriate safety agencies. The cord must have a CEE-22 standard V female connector on one end and meet IEC 320-030
specifications. European power cords must be harmonized
and designated with a HAR marking on the outside of the
cord jacket to comply with the CENELEC Harmonized
Document HD-21.
WARNING
The default voltage setting on the ACPS-17HS is
115V AC. Before applying power, make sure the
voltage switch is set appropriately for the voltage
source in your region.
For AC power supply connections, follow these guidelines:
• Make sure the power switch is in the OFF position (O).
• Plug the AC cord into the connector on the power supply,
then insert the other end of the cord into the AC power
source. If two power supplies have been installed, connect
each power supply to a separate power source.
• Set the power switch to the ON position (I).
• Verify proper connection and operation via the power
(PWR) LED on the power supply front panel. The LED is
lit when the power supply is functioning correctly.
Caution: A fully loaded chassis is rated for 2A AC maximum
current. Make sure that the power supply current is sufficient
to power the chassis. Refer to the front panel text for voltage/
current ratings. Reliable grounding of rackmount equipment
must be maintained. Particular attention should be given to
power supply connections other than direct connections to
the branch circuit (e.g. use of power strips).
