● One MicroUSB-B console port
● One RJ45 serial console port
● One serial management USB Type-A port for more file storage
● Onboard Rangeley central processing unit (CPU) system with 8 GB DDR III RAM, 16 GB iSLC mSATA SSD
● One 10/100/1000BaseT Ethernet management port
● Two hot-swappable redundant power supply units (PSUs)
● Four hot-swappable fan modules
● Standard 1U chassis
The following lists the individual Dell PowerSwitch S5048–ON hardware components that are available for ordering:
● Fan with airflow from I/O side to PSU side—red indicator is normal air flow direction.
● Fan with airflow from PSU side to I/O side—blue indicator is reversed air flow direction.
● AC Power supply with airflow from I/O side to PSU side
● AC Power supply with airflow from PSU side to I/O side
NOTE: Fan modules and power supplies are field replaceable units.
NOTE: All fans and PSUs MUST have the same airflow direction. If you mix the airflow direction, to avoid heat damage to
the switch components, you must correct the mixed airflow direction.
