5 Operation
5.1 Initial Startup—Vertiv™ Services
Startup services are available from Vertiv Services Services. If startup services are included with your unit, Vertiv personnel
will start the Vertiv™ VRC-S and make all settings required for proper operation.
5.2 Initial Startup—User
Once installation is complete, including all cabling and power connections and installation of the rack equipment, the Vertiv
VRC-S is ready for startup.
NOTE: Vertiv recommends installing and preparing rack equipment before starting the Vertiv VRC-S so
that the cooling unit will have a heat load to operate with. Starting up the Vertiv™ VRC with the
maximum heat load can cause erratic operation and may damage the cooling unit.
Refer to the Vertiv VRC user manual, which shipped with the Vertiv VRC-S, for instructions on starting the unit.
5.2.1 Recommended Startup Sequence
Vertiv recommends starting the Vertiv VRC then starting the equipment in the rack. Starting the IT equipment first may
lead to heat spikes in the enclosure before the system cooling stabilizes.
5.3 Operational Settings
The Vertiv VRC-S may be monitored and managed either remotely, over your network through the Geist™ rPDU, or locally
through the attached LCD or with a computer connected to the Geist rPDU or to the Vertiv VRC. Connection through the
Geist rPDU will be made using Vertiv™ Intelligence Director, which is embedded in the Geist rPDU.
5.3.1 Changing Settings with the Geist rPDU
Using the Geist rPDU to monitor and manage the Vertiv VRC-S requires connecting the rPDU to the cooling unit with the
FTDI cable, shipped in the Vertiv VRC kit. See
Connect the Vertiv™ VRC to the Geist™ rPDU on page 28 for more
information on connecting the rPDU to the cooling unit. The Geist rPDU must also be connected to your Ethernet network.
Refer to the Geist rPDU user manual, which shipped with your unit, for details on connecting to your network.
After connecting the rPDU to your network, log in as detailed in the rPDU user manual. You must create an account and
password. Open the
Sensors page and scroll to the Vertiv VRC panel at the bottom of the page.
NOTE: Low temperature alarm is shown under standard conditions.
Check the settings for the cooling unit and adjust as required. The Vertiv VRC must be operated as specified in
Specifications on page 41 .
The Geist rPDU interface, shown in Figure 5.1 on the next page , permits monitoring and managing the Vertiv VRC-S. The
interface recognizes the Vertiv VRC as a sensor. The Sensors page shows the status of the component or function, a wrench
symbol permits changing the configuration if logged in with proper access, the name of the component or function, current
readings and an arrow reveals additional information in a drop-down menu.
For details on changing the settings, refer to the Geist rPDU manual that shipped with the unit.
