Installing the Craft Interface
To install the craft interface, follow this procedure (see Figure 23 on page 42):
1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and
connect the strap to one of the ESD points on the chassis. See “Preventing
Electrostatic Discharge Damage” on page 47.
2. Grasping the craft interface by the top and bottom edges, press it into place.
3. Tighten the screws at the corners of the craft interface.
NOTE: When you install the craft interface in an operating T1600 routing node, allow
several minutes for the LEDs on the craft interface to reflect the current state of the
T1600 routing node.
After you install the replacement craft interface, immediately reinstall the upper front
fan tray.
