SAN Switch 4/32 Description
SWL and LWL SFP
modules release
mechanism
The SAN Switch 4/32 uses an octal-style SFP cage that places SFPs in
close proximity. As a result of the physical space limitation between the
SFPs, HP requires the use of approved SFP modules only.
Using an approved SFP module eliminates issues associated with the fit and
removal of the module. Specifically, SFPs with wide bail latch mechanisms
that are not flush with the body of the SFP or SFPs with “push-tab” removal
mechanisms might prevent the proper insertion or removal of the SFP
module.
At the time of release, the following SFPs were certified for use with the
SAN Switch 4/32:
• HP StorageWorks 4Gb
SW 4PK SFP Transceiver, A7448A
• HP StorageWorks 4Gb SW SnglePK SFP Transceiver, A7446A
• Short wavelength SFP, A6515A* or 300834-B21**
• Long wavelength SFP, 10 km, A6516A* or 300835-B21**
• Long wavelength SFP, 35 km, 300836-B21**
* premerger HP part number
** premerger Compaq part number
LED, system status
The system status LED blink behavior in the SAN Switch 4/32 is different
from that of legacy HP StorageWorks switches. Legacy products blink
system status with amber/off, amber/off. The SAN Switch 4/32 blinks
amber/green, amber/green.
