To install the HLU-200 List 1E into a Litespan-2000 channel bank:
1 Slide the HLU-200 List 1E into the card guides for the desired slot, then
push the unit in until it touches the channel-bank backplane card-edge
connector.
2 Carefully push the unit in until it is entirely within the card guide and the
retaining latch closes.
3 Install the HLU-200 List 1E into the 2000 channel bank.
4 Ensure that the following LEDs illuminate:
• The FAIL LED lights red until the handshake between the bank and
the HLU-200 List 1E is complete.
• The HDSL LED flashes GREEN until an HDSL link is established
between the HLU-200 List 1E and an HRU (when an HRU is
installed).
5 Once the HDSL link has been established, the LEDs return to a normal
operational state as described in
Table 1 on page 3 .
If the HLU-200 List 1E is removed from a slot, it must not be
reinserted for at least 15 seconds. Reinserting it sooner may
temporarily lock the HLU-200 List 1E into an unstable state.
