Grounding And Power Requirements - Tekelec T1000 Hardware Manual

Pre-Installation Site Requirements
Floor Loading
Tekelec products installed in heavy-duty frames are designed for installation on
raised or solid floors, which are recommended to have a distributed load capacity
of no less than 100 pounds per square foot (504 kg/m2). Following are the
maximum weights of Tekelec frames:
• Maximum weight of EAGLE 5 ISS Control or Extension frames: 850 lbs
(386 kg).
• Maximum weight of a two T1000/T1100 server frame (for example, the
MPS frame), including AC and DC LSMS frames: 600 lbs (273 kg).
• Maximum weight of the EOAP frame: 450 lbs (205 kg).
• Maximum weight of an application frame with up to six T1000/T1100
servers: 925 lbs (421 kg).
Use the following equation to calculate the floor loading:
Distributed floor capacity = Total equipment weight/floor area

Grounding and Power Requirements

Before installing a T1000 AS hardware system, refer to the application
documentation to determine whether it is to be installed in an Alternating
Current (AC) or Direct Current (DC) environment. Then, ensure that the
grounding and power requirements in the appropriate following sections have
been met.
• "Grounding Requirements" on page 2-8 (this section describes
requirements both for AC and DC environments)
• "Power Requirements in a DC Environment" on page 2-10
• "Power Requirements in an AC Environment" on page 2-11
Grounding Requirements
Tekelec systems operate as digital isolated ground plane systems in a central
office environment and require a single connection to the central office ground
window. The system's ground cables must provide the sole grounding connection
between the entire system and the central office grounding.
WARNING: Always install an isolator pad between the frame and ground.
Tekelec frames are shipped with isolator pads to completely isolate the frames
from ground. If a non-Tekelec frame is used, an isolator pad must be provided.
