SERVICE COMPONENTS |
Power
All sites are designed to provide sufficient power supplies
to service all equipment within each facility. All power is
backed up by specifically designed back up facility such as
generator and UPS.
Direct Current (-48V DC)
All facilities are equipped with state of
art Direct Current (DC) equipment. The equipment generally
consists of rectifier(s), batteries and distribution equipment/boxes.
4-hour batteries are installed at all sites. All batteries
are charged from mains (AC) supply. Custom designed, installed
and methodically maintained emergency diesel generator automatically
backs this up. Loss of power is immediately visible at NOC
from all sites. NOC manned 24x7x365 to respond immediately
to any loss of power.
Alternate Current (240V AC)
AC power can be supplied between 10 to 32
Amp single phase. 3-phase supply can be accommodated up to
32 Amps 3 phase.
UPS
All AC power is protected by UPS backup.
Generator Back-Up
AC power supply is backed up at all sites by generator and
ancillary equipment. All generator systems are supplied with
fuel tanks with fuel capacity of minimum 3 days, 24 hours
per day at maximum loads. Generators are appropriately maintained
and test run on a monthly basis. The service and test runs
do not require shut-down. Operations and Customer Care will
coordinate with customers to ensure they are aware of impending
tests. These shutdowns do NOT cause any loss of power to customer
equipment.
Floor coverings
All floors are covered by antistatic vinyl.
Grounding
All sites have dual grounding protection: Building earth -
all racks, cable trays and non-communication equipment is
bonded to it Technical (Communications) earth and all communication
equipment is bonded to it via communications earth bars located
within the racks.
Fire Protection
Fire protection is provided in the following form: VESDA smoke
detection and alarm system Pre-action fire protection FM 200
gaseous system Connection to house fire control system. Alarms
are visible by NOC from all sites.
Air Conditioning
All sites have minimum 20% redundant capacity
of cooling. Air conditioning is specifically designed to site-specific
conditions to deliver constant environmental climate of 22°C
and humidity level of 49%. Air conditioning units are state
of art design. Units are either water or air-cooled. Where water
coolers are employed minimum of 20% redundancy is designed in.
Alarms are visible by NOC from all sites. |
