Installation and Quick Start 9
Expansion/Triple Chassis Installation
When to use an
Expansion
Chassis
Use an Expansion Chassis or a Triple Expansion Chassis if the
UPS has no card slot available.
When you install the Management Card in the chassis, it
communicates with the UPS through the cable connection
between the chassis and the UPS.
When to use the
AC adapter
(AP9505)
Use the optional AC adapter with a chassis under the following
circumstances:
• To connect the chassis to an independent AC input so
that the Management Card can continue to operate if the
UPS is turned off or fails.
• To provide the APC management products mounted in a
Triple Expansion Chassis with more current than the
UPS can provide through the UPS-to-chassis cable.
– A Silcon UPS provides up to 500 mA.
– A Matrix-UPS, Smart-UPS, or Symmetra UPS
provide up to 200 mA.
Step 1:
Disconnect the
chassis from all
power
Make sure that the chassis is disconnected from any power
source:
• Disconnect the chassis cable from the UPS.
• If the UPS uses an AC adapter, disconnect that adapter
from the chassis.
Note
Use only a Silcon Triple Chassis Protocol
Converter (AP9604S) with a Silcon UPS or an
AIS 5000 UPS.
