TABLE B-9Zone 3 Signal Descriptions (Continued)

Signal Name	Description
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#,	JTAG signals. Signal direction shall follow AMC.0 specification.
