66 ETEP Installation Guide
Obtaining a License for Replacement Units
When replacing the ETEP with a spare, the replacement ETEP will run at full throughput for a grace
period. During the grace period, contact customer support to report the RMA unit and to receive a new
license for the replacement. Licenses are linked to the serial number of the ETEP on which they are
installed. You cannot install a license intended for one ETEP on a different ETEP.
Upon receipt of the new license, install it on the ETEP as described in “Entering a Throughput License”
on page 80.
Replacing a Power Supply
The ET1000A and ET10000A come with dual internal power supplies. In the event of a failure, the
power supplies can be removed and replaced in the field.
Replacing the ET1000A Power Supply

To replace a power supply in the ET1000A:
1 Unplug both power supplies at the power source.
2 On the rear panel, lift the power cord clip on the affected power supply, and then remove the power
cord from the receptacle (Figure 43).
