Teledyne Lecroy PCI Express Gen4 x16 EDSFF User manual

Introduction
Use this document for quick installation and setup.
Teledyne LeCroy's PCIe Express Gen4 x16 EDSFF Host Adapter provides a quick and simple means for test and debug of
EDSFF form factor Solid State Drives (SSDs) based on PCI Express (PCIe) protocols. They support data rates of 2.5 GT/s,
5.0 GT/s, 8.0 GT/s and 16.0 GT/s. Each host adapter also supports side band signals such as PERST#, CLKREQ# and
SMBus (SMBCLK, SMBDAT).
Two host adapters with identical functionality support the different mechanical form factors E1.L (PE-1002-2-X16Host-X)
with a long bracket and E1.S (PE-1002-2-X16Host2-X) with a short bracket.

Assembly Steps
Before using the adapter make sure the device bracket is installed as instructed.
Attach the bracket to the EDSFF Interposer using four (4) supplied screws (PN: 42A0000001238), using a Phillips-head
screw driver. See figure below.

An optional adapter is provided for cases when testing a caseless EDSFF device. The device needs to be secure to the
adapter before it can slide in to the host adapter bracket. Attach the caseless EDSFF Device to the adapter using four (4)
supplied screws.

Connections
Perform to the following steps to connect each Gen4 x16 EDSFF Host Adapter (see the sample image below):
1. Slide the EDSFF memory device into the device bracket and carefully push it into it’s mating connector on the EDSFF
Host Adapter.
2. Make sure the power for the DUT is sourced correctly using switches SW12 (3.3V Source), SW11 (12V Source) and
SW15 (12V Power to DUT).
3. The factory default positions for SW5 (Lane Width Configuration): SW5.1 OFF, SW5.2 ON, SW5.3 OFF, SW5.4 OFF.
4. SW4 shunt 1 -> 2 for single port operation or shunt 2 -> 3 for dual port operation.
5. SW7 is ON for Activity LED.
6. SW10 is ON for DUT Power Status LED.
7. The PERST#/CLKREQ# control function is set by SW 6.
8. Plug the adapter with the device under test in any PCI Express slot.
9. Connect the power supply to the external power jack (J15) if needed.

Table 1: SW4
Note: Controls DUALPORTEN# sideband signal for single vs. dual
port operation.
Table 2: SW5
Note: Configure the PCIe Host Connector for the selected link width.
Table 3: SW6
Note: PERST#/CLKREQ# is multiplexed in EDSFF connector. In
Single Port mode (SW4), this signal acts as CLKREQ# signal. In
Dual Port mode(SW4) this sideband signal acts as PERST#.
Table 4: SW7
Note: Control for the LED/ACTIVITY sideband signal on EDSSF
connector. ACTIVITY is an input signal to the Host and is reserved
for future use. LED is active high output signal, used to drive Amber
LED from the Host. The header provides ability to drive this signal
high.

Table 5: SW10
Note: The switch provides the ability toisolate these status indication
LEDs on this adapter and restrict the LEDs from power drawing.
SW10 ON means LEDs connected to the DUT power will be ON,
SW10 OFF means that the LEDS are disabled and drawing no
current.
Table 6: SW11
Note: Switch used to select the 12V power source for the EDSFF
Connector.
Table 7: SW12
Note: This switch is used to select the 3.3V power source for on
board circuitry in host adapter. 3.3V source could be either regulated
supply or from the PCIe slot (3P3V_Host).
Table 8: SW15
Note: Jumper closed for PWRDIS signal is enabled, which indicates
the device to shut off 12V and related circuitry. Open for normal
operation.
