Figure 139: TX Matrix Router 240-A DC Power Supply
Each power supply has either an active circuit breaker or an active current limiter for each
output voltage it provides. There are no passive fuses in the TX Matrix router that must
be replaced.
Each power supply is cooled by its own internal cooling system.
The TX Matrix router supports the DC power supplies in Table 69 on page 290.
NOTE: Mixing a two-input 160-A power supply and a three-input 240-A power
supply in the same chassis is not supported during normal operations.
