director 2/64 service manual 3–41
Repair Information
NOTE: When powering on the director after removing and replacing a faulty FRU, the
amber system error LED may remain illuminated. Clear the system error LED as part of the
replacement procedure.
Power-Off Procedure
Powering the director off and on (performing a power cycle) resets all logic cards and
executes POSTs. When performing a power cycle, wait approximately 30 seconds
before switching power on.
NOTE: When the director is powered off, the operation of attached Fibre Channel devices is
disrupted. Do not power off the director unless directed to do so by a procedural step or the next
level of support.
To power-off the director:
1. Notify the customer the director will be powered off. Ensure the customer’s
system administrator quiesces Fibre Channel frame traffic through the director
and sets attached devices offline.
2. Set the director offline (Set Offline State on page 3–44).
3. At the bottom rear of the director, set the power switch (circuit breaker) to the
down position. The director powers off.
4. If servicing the director, disconnect power cords from the input power module at
the bottom rear of the director. This step is not required when performing a power
cycle.
IPL the Director
A director IPL should only be performed if failure of a CTP2 card is indicated. Do not
IPL the director unless directed to do so by a procedural step or the next level of
support. A director IPL performs the following functions:
• Resets the functional logic for the active CTP2 card only. An IPL does not reset
the backup CTP2 card, SBAR cards, or UPM cards. All director switching
operations continue unaffected.
NOTE: An initial machine load (IML) performs essentially the same functions, but resets
both CTP2 cards. A director IML is initiated by pressing and holding the white IML button
(on the faceplate of either CTP2 card) for three seconds.
• Loads firmware from the CTP2 card FLASH memory without cycling director
power.
