opens, ensure that no cable is snagged or pinched. Also as the drawer
opens, half-spools at the sides of the drawer will move with it towards the
front. If a half-spool does not reach the front of the drawer, move it
manually. The rear half-spools are fixed. Refer to the figure "Locating a
fiber cable in a fiber management unit NTHW50" (page 794).
5 Locate the tray inside the drawer that contains the fiber cable being
replaced. Access a lower tray by lifting the stack above it from the center
edge up towards the nearest side.
6 Use the label information to confirm that you found the correct cable.
7 Unravel the fiber cable from the tray and loosely place it aside temporarily.
8 Ravel the replacement cable onto the tray in and out the rear corner, and
route it along the same path as the other fiber cables on that side of the
drawer.
9 After ravelling and routing, ensure that the tape on the cable resides
outside the drawer close to the fiber unit and with the same amount of
cable slack as the other cables in the curlie ties. Adjust as required.
10 Slowly close the drawer to test the slackness of the replaced cable.
Closure is indicated by a click sound and the faceplate is flush with the
other drawer's faceplate. Adjust the slackness if the cable shows tension.
11 Route the cable up to the other end connection. Follow a parallel path to
the cable being replaced. Leave the cable unconnected.
12 Fasten the replacement cable in place. Ensure that no portion of the cable
is stressed by a bend or a tie-wrap.
13 Carefully remove the temporary electrical tape from the cable. Avoid
cutting or nicking the cable sheath. Avoid crimping or pinching the cable
during its removal.
