ACT_LED# LAN 0 (Management) activity indicator signal for LED (active low).
LINK_LED# LAN 0 (Management) LINK indicator signal for LED (active low).
PCI_CFG PCI Express bus configuration signal. It shall be grounded on RTMs that use a single x8
PCI Express bus and pulled up on the ATCA with 10Kohm resistor to management
power. On RTMs that expect two x4 PCI-Express busses this pin will float (not be
connected). Two x4 PCI-Express busses are intended for RTM implementations that
desire to avoid PCI-Express switch in order to reduce latency.
ARTM# ARTM# signal shall be grounded on ARTMs that implement MMC controller as defined
by AMC.0 specification. This signal shall be pulled up with 10Kohm resistor to
management power on the ATCA node blade server.
SLAN_TX GBEthernet SerDes transmit differential pair signals.
SLAN_RX GBEthernet SerDes receive differential pair signals.
PETx PCI-Express transmit differential pair signals.
PERx PCI-Express receive differential pair signals.
PCI_RST# PCI-Express reset signal. Logic low shall reset downstream PCI-Express devices on
ARTM.
TCLKA PCI-Telecom clock A 19.44MHz, differential pair into RTM (ATCA CLK2) as defined in
AMC.0 specification.
TCLKB PCI-Telecom clock B 19.44MHz, differential pair out from RTM (ATCA CLK3) as defined
in AMC.0 specification.
TCLKC PCI-Telecom clock C 8kHz, differential pair into RTM (ATCA CLK1) as defined in AMC.0
specification.
TCLKD PCI-Telecom clock D 8kHz, differential pair out from RTM as defined in AMC.0
specification.
FCLKA Fabric clock, as defined in AMC.0 specification. Intended to be used for PCI-Express 100
MHz spread spectrum clock.
TCK, TMS, TRST#,
TDO, TDI JTAG signals. Signal direction shall follow AMC.0 specification.
