IMPORTANT! Each IP address and Group ID must be unique on the same network. Do not duplicate addresses unless
the units are on different networks (utilizing the Liebert® iCOM™-S Gateway).
3.1.2 Dimensions and Clearance
For the panel appliance, the dimensions of the assembled panel mount universal mounting bracket are:
•Width = 26.4 in. (671 mm)
•Height = 25.75 in. (635 mm)
•Footprint = 26.5 in. (664.2 m) wide x 16 in. (407 mm) deep
For the panel appliance, both wall- and desk-mount configurations, the following clearances apply:
•Up to 24 in. (610 mm) on the left side to accommodate the DIN rail (because it may be extended to mount
ancillary equipment).
•27 in. (660 mm) in front of the system to open the front door.
•6 in. clearance required for cable management.
Refer to submittal DPN003318 in Submittal Drawings on page129 for more details on size.
In wireless configurations consider:
•In open space with clear line-of-sight, the wireless gateway has a receiving range of more than 1,000 ft. (305m).
In traditional data center applications with dense/metal obstructions however, it is recommended to maintain a
radius of 200 ft. (61m) or less between the wireless gateway and communicating wireless sensors to increase
sensor strength, decrease signal to noise ratio and to increase battery life.
•Use best practices for optimal results in locating wireless gateways: do not install directly behind obstructions, on
other side of walls or at a right angle to the floor, inside metal enclosures. It is also recommended to position the
antenna at a right angle to the data center floor.
3.1.3 Cabling and Power Requirements
•Install Vertiv™ Liebert® iCOM™-S within 328 ft (100 m) of the furthest unit/device to be connected via Ethernet
cable, including wireless gateways and iCOMâ„¢-S displays on the cooling units. Greater distances require signal
amplifiers or powered repeating/network switches.
•Provide duplex 110-120V, 60Hz input power protected by a dedicated circuit breaker. Vertiv recommends a 120-
VAC source within 5 ft (2 m) of the Liebert® iCOM™-S. A 3 ft (0.9 m) and 6 ft (1.8 m) power cable ships with
iCOMâ„¢-S.
•Vertiv also recommends installing a UPS/battery backup power feed.
•The Liebert® iCOM™-S panel appliance includes a single power feed that needs to have branch circuit protection
upstream. The Liebert® iCOM™-S 1U workstation appliance can be ordered with an optional second power supply
pre-installed where two independent power feeds can be connected to the appliance directly.
3.1.4 Metric and System Configuration Considerations
•Agreement with the end user on desired system calculations to perform at the Unit, Group, Room and Site levels.
Refer to Metrics Configurations on page19 for available calculations at the various levels.
•BMS points to be mapped (as metrics/calculations have to be enabled for the results to be available for
communication).
•Known site altitude as this set value impacts calculation results.
•Agreed upon list of unit data points to include in the initial Room Report view.
