Servicing
While the unit is mounted in the rack and fully cabled, you can swap out the power supplies, front panel,
or the primary electronics assembly (main board).
Note:
Except for replacing the power supply in a 170-101403Q0x frame with hot swappable power
supplies, all these tasks must be completed with the unit off and power cords disconnected from the
frame.
Procedures for switching main PCB assembly and front panel and fan bracket assemblies are the same
for both 170-101715Q0x and 170-101403Q0x frames.
Customer-replaceable parts:
•
SNP-FNPL-ASSY:

(on page
) for SNP-GW-3GX32 frames
•
SNP-FNPL-HS-QF:
Front Panel Assembly
(on page 138) for SNP-GW-3GX32-HS-QF frames
•
SNP-MAIN-PCB-ASSY
Main PCB Assembly (170-101712Q0x)
(on page 145) for both SNP-GW-3GX32
and SNP-GW-3GX32-HS-QF frames
•
SNP-350W-ACPS-ASSY:

To remove and replace any of these hardware components, you will need a Phillips screwdriver with #2
bit.
Front Panel Assembly
The front panel unit (SNP-FPNL-ASSY for SNP-GW-3GX32 frames or SNP-FPNL-HS-QF for SNP-GW-3GX32-
HS-QF frames) includes the display, metalwork, and all six cooling fans. Individual parts of the front
panel are not field-serviceable, but you can remove and replace the entire front panel.
In SNP-GW-3GX32 frames, to replace either the Main PCB Assembly (170-101712Q0x) (on page 145) or
the Power Supply Assembly (170-101715Q0x) you must first power down the unit before removing the
front panel assembly.
In SNP-GW-3GX32-HS-QF frames, you only need to remove the front panel when replacing the Main PCB
Assembly (170-101712Q0x) (on page 145). The hot swappable power supplies can be accessed
separately. See Hot-Swappable Power Supply (170-101403Q00) for more information.
