Primary management
ports:
Out-of-band management using mini-USB 2.0 console port
Memory: DDR4 with ECC. VEP1425 has 8 GB onboard, with one SO-DIMM available for expansion. VEP1445
has 16 GB on board with one SO-DIMM available for expansion. VEP1485 has one system with 32 GB
total (16 GB onboard and 16 GB using SO-DIMM), and another system offering with 64 GB total (32
GB onboard and 32 GB using SO-DIMM).
USB ports:
● Two USB type-A receptacle (female) ports supporting a mass storage device (USB flash drive) or
external LTE modem. The port supports USB 3.0 with maximum data rates of 640 Mbps.
● Micro-USB port (receptacle) used as a console port for management. A typical scenario would be
to connect a laptop personal computer to this port using a standard male USB Type-A plug to
micro-USB cable.
