Verilink Access System 2000: The Basics 4-5
Quint-line Shelf
Grounding
The QLS 2500 is ordered with an internal AC or DC power supply.
If the shelf is ordered with the AC power supply, the system ground
is internal, and no further grounding is required. If the system is
ordered with the internal DC power supply, there is one grounding
point (CGND) on the rear terminal block. Connect the chassis
ground to this connector.
AC Power Connections
The following section addresses the AC power connections to the
Multi-line, Quint-line, and Dual-line shelves.
NOTE: If your site has UPS power, Verilink recommends connecting
one AC power supply to the UPS and the other power supply
directly to local commercial power. If there is a failure of the
UPS, service will continue.
Multi-line and
Quint-Line
Shelves
Plug one end of each power cord into the associated receptacle at
the back of the power supply. Insert the other end of the cord into
your electrical outlet.
Dual-line Shelf For the PWR 2940 or PWR 2950 power supply, connect the 5.5 VDC
power supply outputs to the J1 receptacle (and J2 for redundant
power supplies) at the back of the Dual-line shelf. Refer to
