APC UPS Network Management Card 2 AP9630 - Manual (Page 10)

6 Installation Manual
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 Network Management Card in the chassis, the Network
Management Card 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 Network
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.
Note: A Smart-UPS or Symmetra UPS can provide up to
200 mA.
For information about the current requirements for APC
management products, see “How to Install Multiple
Management Cards” on page 18.
Step 1: Disconnect the chassis from all power
Make sure that the Expansion Chassis or Triple Expansion Chassis is
disconnected from any power source:
1. Disconnect the chassis cable from the UPS.
2. If the chassis uses an AC adapter (AP9505), disconnect that adapter from
the chassis.
Step 2: Install the Network Management Card
If the UPS uses multiple APC management products, you must install them in
the correct order for them to operate properly.
