Guidelines for handling SFP and SFP+ modules
36 EMC VNX7500 Parts Location Guide
Small form-factor (SFP) modules are compact, hot-pluggable transceivers inserted into
the SFP or SFP+ slot of an I/O module in a VNX7500 platform. This transceiver module
provides uplink optical interfaces, laser send or transmit (TX) and laser receive (RX). An
SFP or SFP+ transceiver module is hot-swappable. You can replace an SFP or SFP+ from
the rear of the SP or Data Mover while the platform is powered up.
Note: The SFP or SFP+ part number is visible only when the SFP or SFP+ is removed from an
I/O module port.
Before you install SFP or SFP+ modules in a Block and File VNX7500 platform or attempt to
operate or service a Block and File VNX7500 platform equipped with SFP modules, you
must read and observe the important safety information in this section of the document.
The Block and File VNX7500 platform SFP or SFP+ modules are equipped with a Class 1
Laser, which emits invisible radiation. Do not stare into open optical ports. The following
warnings apply to the all SFP and SFP+ modules.
Class 1 laser product.
Because invisible laser radiation can be emitted from the aperture of the port when no
fiber is connected, avoid exposure to laser radiation and do not stare into open
apertures.
Laser radiation is present when the system is open and interlocks bypassed.
Only trained and qualified personnel should be allowed to install, replace, or service this
equipment.
Use these guidelines when you work with SFP and SFP+ modules:
SFP and SFP+ modules are static sensitive. Wear an ESD-preventive wrist strap that is
◆
connected to the rack in order to prevent ESD damage.
SFP and SFP+ modules are dust sensitive. Always store the devices with dust plugs
◆
installed in the optical bores.
Do not remove and insert an SFP or SFP+ module more often than is necessary.
◆
Repeated removals and insertions of an SFP or SFP+ module can shorten its useful
life.
