Operation USB Ports The VL-EPMs-M1 includes four USB channels. There are two USB ports with standard USB Type A connectors, located on the baseboard at locations J4 and J5 (models A and C). The 10- pin header at location J6 provides two USB channels.
Operation SATA Ports The VL-EPMs-M1 provides one or two serial ATA (SATA) ports, which communicate at a rate of up to 3.0 gigabits per second. The SATA connectors at location J3 and J8 are standard 7-pin SATA friction latching connectors (with cable VL-CBR-0701) or mechanical latching (VL-CBR- 0702).
SATA RAID S ONFIGURING A To configure a SATA RAID set for two drives, perform the following steps. This procedure assumes that you have installed the VL-EPMs-M1 on a VersaLogic SBC and attached power and data cables to two SATA drives. Warning! Performing these steps will delete any existing data on the drives.
The VL-F29 series of mSATA modules provide flash storage of 8 GB, 16 GB, or 32 GB. To secure a Mini Card or mSATA module to the VL-EPMs-M1 use two screws (M2 x 5 mm, Philips, pan head, 4 mm, stainless) and two washers (M2, split lock, OD 4.4 mm, stainless).
