Replacing a T1E1 Module in the E4G-200 Router
You can replace a T1/E1 module without powering down the router; however, you must reboot the
router to initialize the newly installed T1/E1 module.
To replace a T1/E1 module:
1 Attach an ESD-preventive wrist strap to your wrist and connect the metal end to an appropriate
ground point on the rack.
2 Completely loosen the captive retaining screws and slide the installed T1/E1 module out of the
router
(Figure
55).
