Reinstalling feature licenses Feature licenses (or keys) must be reinstalled after performing a factory reset on an Edge Switch or Director to regain use of the licensed features (for example, SANtegrity Binding). CTP controls port lights Port lights on the Edge Switches and Directors are controlled by the CTP. Certain activities such as firmware updates, IPLing the CTP, or switching over to the backup CTP (Director) can cause these port lights to extinguish momentarily until control is reasserted by the CTP. The actual Fibre Channel traffic is not affected during these times. Full-fabric capability for Edge Switch 2/12 Unlike other Edge Switch and Director products, a PFE key controls Edge Switch 2/12 E_Port-to-E_Port connections. After purchasing and installing the feature key, you can configure for E_Port connections on any of the active ports. The feature key includes distance support. With firmware 06.00.00 and later, the Edge Switch 2/12 ships with five BB_credits allocated to each port. After activation of the Full Fabric feature on a switch, each port has 12 BB_Credits allocated to support up to 12-km links at 2-Gb/s speed. Support for speed Auto-Negotiate Auto-negotiate is supported. However, HP recommends that the port speed for E_Ports (for Interswitch links, or ISLs) be set to a specific port speed (1Gb/sec, 2Gb/sec, or 4Gb/sec as appropriate for the speed of the Directors or Edge Switches being connected) instead of to Negotiate. Using a specific port speed decreases the time for a fabric build in response to some perturbation event in the fabric. Similarly, setting a specific port speed for N_Ports also decreases fabric build time. However, setting a specific port speed for N_Ports is not required. There are a few older HBA devices that do not always succeed in logging in to a switch port when the port speed is set for auto-negotiate. Workaround If an older HBA has difficulty logging into a switch port that has its port speed configured as Negotiate, configure that port speed to 1Gb/sec, 2Gb/sec, or 4Gb/sec according to the operation speed of the HBA connected to that port.

Reinstalling feature licenses
Feature licenses (or keys) must be reinstalled after performing a factory reset on an Edge Switch or
Director to regain use of the licensed features (for example, SANtegrity Binding).
CTP controls port lights
Port lights on the Edge Switches and Directors are controlled by the CTP. Certain activities such as
fi
rmware updates, IPLing the CTP, or switching over to the backup CTP (Director) can cause these port
lights to extinguish momentarily until control is reasserted by the CTP. The actual Fibre Channel traf
fi
c is
not affected during these times.
Full-fabric capability for Edge Switch 2/12
Unlike other Edge Switch and Director products, a PFE key controls Edge Switch 2/12 E_Port-to-E_Port
connections. After purchasing and installing the feature key, you can con
fi
gure for E_Port connections on
any of the active ports.
The feature key includes distance support. With
fi
rmware 06.00.00 and later, the Edge Switch 2/12
ships with
fi
ve BB_credits allocated to each port. After activation of the Full Fabric feature on a switch,
each port has 12 BB_Credits allocated to support up to 12-km links at 2-Gb/s speed.
Support for speed Auto-Negotiate
Auto-negotiate is supported. However, HP recommends that the port speed for E_Ports (for Interswitch
links, or ISLs) be set to a speci
fi
c port speed (
1Gb/sec
,
2Gb/sec
, or
4Gb/sec
as appropriate for the
speed of the Directors or Edge Switches being connected) instead of to
Negotiate
. Using a speci
fi
c
port speed decreases the time for a fabric build in response to some perturbation event in the fabric.
Similarly, setting a speci
fi
c port speed for N_Ports also decreases fabric build time. However, setting a
speci
fi
c port speed for N_Ports is not required.
There are a few older HBA devices that do not always succeed in logging in to a switch port when the
port speed is set for auto-negotiate.
Workaround
If an older HBA has dif
fi
culty logging into a switch port that has its port speed con
fi
gured as
Negotiate
,
con
fi
gure that port speed to
1Gb/sec
,
2Gb/sec
, or
4Gb/sec
according to the operation speed of the
HBA connected to that port.

Issue
Workaround
For the Director 2/64 in a FICON environment,
when a QPM is swapped for an XPM, or an
XPM is swapped for a QPM, the PDCMs of the
affected ports are not cleared. PDCMs cannot be
con
fi
gured via HAFM after this happens.
Do not immediately replace a QPM port card with an
XPM port card, or an XPM port card with a QPM port
card. To make this change, remove the
fi
rst port card
(QPM or XPM), install a UPM port card temporarily (for
two minutes), and then remove the UPM and install the
desired port card (QPM or XPM).
For Edge Switches, the alias database persists after
a con
fi
guration reset, where it should be cleared.
Alias Database can be successfully cleared through CLI
and EFCM basic.
Attempts to activate a large zone set through OSMS
when CT authentication is enabled occasionally
may not be successful.
Temporarily disable CT authentication, and then
activate the zone set.
