T1600 Routing Node Upgrade Guide T1600 Routing Node Environmental Specifications Table 5 on page 44 specifies the environmental specifications required for normal T1600 routing node operation.
T1600 Routing Node DC Power Specifications Table 6: Power System Electrical Specifications Item Specification DC input voltage Operating range: –40.0 to –72 VDC NOTE: If the input voltage from the DC power source drops below –37.5 to –39.5 VDC, the routing platform automatically shuts down. During automatic shutdown, the circuit remains active. When the input voltage returns to –43.0 to –44.0 VDC, the router automatically starts up again and the system returns to normal operation within 30 minutes.
T1600 Routing Node Upgrade Guide NOTE: If you plan to operate a maximally configured T1600 routing node, we recommend that you provision at least 64 A @ –48 VDC for each power supply input in the system. Although Input 0 requires less power, we recommend provisioning the same amount of power for each input to avoid the possibility of connecting the lower-powered DC cable to Input 1 or Input 2. Use a facility circuit breaker rated for 80 A (–48 VDC) minimum for each power supply input.
Preventing Electrostatic Discharge Damage Preventing Electrostatic Discharge Damage Many T1600 routing node hardware components are sensitive to damage from static electricity. Some components can be impaired by voltages as low as 30 V. You can easily generate potentially damaging static voltages whenever you handle plastic or foam packing material or if you move components across plastic or carpets.
