VGA Header
Connect an IDC 16-pin VGA extension cable to JVGA1 for a VGA connection (PN: CBL-
CDAT-0850).
EDSFF Short Header
EDSFF Short is a new form factor designed to overcome thermal and capacity shortcomings
of previous PCI-E storage technologies. When used with a right-angle connector, the EDSFF
Short device allows better airflow in a 1U server set-up. JEDSFF1/JEDSFF2 each offers
PCI-E3.0 x4 lanes for the latest low latency NVMe storage module. Please note that JEDSFF1/
JEDSFF2 are not hot pluggable and are shared with JMD3/JMD4 (M.2 M-Keys), so usage
are restricted to one device at a time.
JSIM1
The JSIM1 slot supports a Nano SIM card.
JSLOT1 - JSLOT4
Supermicro introduces the Advanced I/O Module (AIOM), the latest expansion card feature
offering PCI-E3.0 x8 lanes in each slot which can be utilized to offer additional LAN ports, VPU,
storage devices, etc. on the motherboard. Please visit the Supermicro website for all available
module options. Please also keep in mind that it is mandatory that power be unplugged prior
to removing or installing an AIOM module card to any of these four expansion slots.
