Grass Valley PFR 500/E Dec 10 2001 - Manual (Page 43)

Monitoring PFC500/E status
November 17, 2000 PFC 500/E Instruction Manual 43
Status lights visible at the back of the PFC500/E
If the RC Check light is on, you should look at the other Check lights to determine
which CRU is faulty. If a check light on a CRU remains on, you should replace that
CRU as soon as possible.
If a non-redundant CRU fails in a PFC 500, the system may be inoperable while you
replace the CRU. If a redundant CRU fails, high availability will be compromised
until you replace the faulty CRU.
