BLADE OS 5.1 Release Notes
BMD00098, December 2009 5
The GbESM contains three 10 Gigabit Small Form-factor, Pluggable (SFP+) slots. The 10Gb SFP+
slots can accept 1Gb copper transceivers, 10Gb optical transceivers, or Direct Attach Cables
(DAC).
Note – If a DAC is not programmed to meet MSA specifications (including length identifier), the
switch disables the port and generates a syslog message indicating that the DAC is not approved.
The GbESM does not disable the SFP+ ports when using MSA-compliant DAC cables. For best
results, the following cables have been qualified to work with the switch:
